How to assign value to variable from a google API Json Response c#

I am trying to assign the value of a key from an async JSON response to a variable, the JSON key in question is the "threatType" Key. I am querying google's safebrowsing v4 API and I get a good response, the problem is when I try to assign a key to a variable nothing is assigned. Here's my code:
public static async Task<string> CheckUrl( string Api_Key, string MyUrl)
{
safeBrowsing_panel i = new safeBrowsing_panel();
var service = new SafebrowsingService(new BaseClientService.Initializer
{
ApplicationName = "Link-checker",
ApiKey = Api_Key
});
var request = service.ThreatMatches.Find(new FindThreatMatchesRequest()
{
Client = new ClientInfo
{
ClientId = "Link-checker",
ClientVersion = "1.5.2"
},
ThreatInfo = new ThreatInfo()
{
ThreatTypes = new List<string> { "SOCIAL_ENGINEERING", "MALWARE" },
PlatformTypes = new List<string> { "ANY_PLATFORM" },
ThreatEntryTypes = new List<string> { "URL" },
ThreatEntries = new List<ThreatEntry>
{
new ThreatEntry
{
Url = MyUrl
}
}
}
});
var response = await request.ExecuteAsync();
string json = JsonConvert.SerializeObject(await request.ExecuteAsync());
string jsonFormatted = JToken.Parse(json).ToString(Formatting.Indented);
Console.WriteLine(jsonFormatted);
return jsonFormatted;
}
I created classes to parse the json:
public class ThreatRes
{
public string threatType;
}
public class RootObjSB
{
public List<ThreatRes> matches;
}
And I call it with:
string SB_Result = await CheckUrl("MyAPIKey", "Bad_URL");
RootObjSB obj = JsonConvert.DeserializeObject<RootObjSB>(SB_Result);
The JSON response from google:
{
"matches": [
{
"cacheDuration": "300s",
"platformType": "ANY_PLATFORM",
"threat": {
"digest": null,
"hash": null,
"url": "http://badurl.com/",
"ETag": null
},
"threatEntryMetadata": null,
"threatEntryType": "URL",
"threatType": "SOCIAL_ENGINEERING",
"ETag": null
}
],
"ETag": null
}
I need help please.

So I tried using JavaScriptSerializer and it seemed to work just fine, I also reconstructed my classes to parse all the properties on the JSON response.
Reconstructed Classes:
public class Threat
{
public object digest { get; set; }
public object hash { get; set; }
public string url { get; set; }
public object ETag { get; set; }
}
public class Match
{
public string cacheDuration { get; set; }
public string platformType { get; set; }
public Threat threat { get; set; }
public object threatEntryMetadata { get; set; }
public string threatEntryType { get; set; }
public string threatType { get; set; }
public object ETag { get; set; }
}
public class RootObjSB
{
public List<Match> matches { get; set; }
public object ETag { get; set; }
}
and i deserialize it like this:
string SB_Result = await CheckUrl("MyAPIKey", "Bad_URL");
var obj = new JavaScriptSerializer().Deserialize<RootObjSB>(SB_Result);
string threat = obj.matches[0].threatType;
Console.WriteLine(threat);
I really don't know why the first option I tried didn't parse the data correctly but this was how I overcame that problem. Hope it helps anyone going through the same thing

How to encode text using File.WriteAllLines?

I was trying to make a txt file, then rename the extension to .json, I have the encoding step and the WriteAllLines step done, but how do I encode the text?(I have the string needed to write)
Here's the code
string[] lines = { "{", "\"version\": 1,", "\"schema_version\": 2,", "",
$"\"id\": \"{textBox14.Text}\",", "", $"\"title\": \"{textBox7.Text}\",",
$"\"title_localized\": \"{textBox18.Text}\",", "", $"\"artist\": \"{textBox6.Text}\",",
$"\"artist_localized\": \"{textBox8.Text}\",", $"\"artist_source\": \"{textBox9.Text}\",",
$"", $"\"illustrator\": \"{textBox10.Text}\",", $"\"illustrator_source\": \"{textBox11.Text}\",",
$"", $"\"charter\": \"{textBox13.Text}\",", $"", "\"music\": {",
$"\"path\": \"{textBox4.Text}\"", "}", "\"music_preview\": {", $"\"path\": \"{textBox5.Text}\"", "}",
"\"background\": {", $"\"path\": \"{open3.FileName}\"", "}",
"\"charts\": [", "{", "\"type\": \"easy\",", $"\"name\": \"{textBox15.Text}\",",
$"\"difficulty\": {numericUpDown1.Value},", $"\"path\": \"textBox1.Text\"", "},",
"{", "\"type\": \"hard\",", $"\"name\": \"{textBox16.Text}\",", $"\"difficulty\": {numericUpDown2.Value},",
$"\"path\": \"{textBox2.Text}\"", "},", $"]", $"", "}" };
Encoding utf8WithoutBom = new UTF8Encoding(true);
File.WriteAllLines($#"C:\Users\Public\Desktop\level files\{textBox14.Text}\level.json", lines);
It was supposed to be something like this:
https://cytoid.io/level.json

Short answer:
Change this:
File.WriteAllLines($#"C:\Users\Public\Desktop\level files\{textBox14.Text}\level.json", lines);
to this:
File.WriteAllLines($#"C:\Users\Public\Desktop\level files\{textBox14.Text}\level.json", lines, utf8WithoutBom);
Long answer:
You shouldn't be generating JSON like this; you should be using a dedicated serializer. With your current solution, if a user enters an invalid character, your JSON will immediately become invalid. So, as a solution you could use Newtonsoft's JSON.Net. Here is an example:
Class definitions
public class Item
{
public int Version { get; set; }
public int SchemaVersion { get; set; }
public string Id { get; set; }
public string Title { get; set; }
public string TitleLocalized { get; set; }
public string Artist { get; set; }
public string ArtistLocalized { get; set; }
public string ArtistSource { get; set; }
public string Illustrator { get; set; }
public string IllustratorSource { get; set; }
public string Charter { get; set; }
public ItemMusic Music { get; set; }
public ItemMusicPreview MusicPreview { get; set; }
public ItemBackground Background { get; set; }
public List<ItemChart> Charts { get; set; }
}
public class ItemMusic
{
public string Path { get; set; }
}
public class ItemMusicPreview
{
public string Path { get; set; }
}
public class ItemBackground
{
public string Path { get; set; }
}
public class ItemChart
{
public string Type { get; set; }
public string Name { get; set; }
public int Difficulty { get; set; }
public string Path { get; set; }
}
Object initialization and serialization
var item = new Item
{
Version = 1,
SchemaVersion = 2,
Id = textBox14.Text,
Title = textBox7.Text,
TitleLocalized = textBox18.Text,
Artist = textBox6.Text,
ArtistLocalized = textBox8.Text,
ArtistSource = textBox9.Text,
Illustrator = textBox10.Text,
IllustratorSource = textBox11.Text,
Charter = textBox13.Text,
Music = new ItemMusic
{
Path = textBox4.Text
},
MusicPreview = new ItemMusicPreview
{
Path = textBox5.Text
},
Background = new ItemBackground
{
Path = open3.FileName
},
Charts = new List<ItemChart>
{
new ItemChart
{
Type = "easy",
Name = textBox15.Text,
Difficulty = numericUpDown1.Value,
Path = textBox1.Text
},
new ItemChart
{
Type = "hard",
Name = textBox16.Text,
Difficulty = numericUpDown2.Value,
Path = textBox2.Text
}
}
};
var settings = new JsonSerializerSettings()
{
ContractResolver = new DefaultContractResolver
{
NamingStrategy = new SnakeCaseNamingStrategy()
}
};
var json = JsonConvert.SerializeObject(item, settings);
File.WriteAllText($#"C:\Users\Public\Desktop\level files\{textBox14.Text}\level.json", json, new UTF8Encoding(true));
You could also use an anonymous type instead of creating the full class definition, of course:
var item = new {
Version = 1,
SchemaVersion = 2,
Charts = new List<object>
{
new {
Type = "easy"
}
}
}
and then just serialize this.

How to assign Room to an Event for meeting using Microsoft Graph API in a UWP App

I am calling the API for creating a meeting on a fixed date & time. I am using Microsoft Graph API for this. Here is the URL
var url = "https://graph.microsoft.com/v1.0/me/events";
I have taken care of the Authentication part and my code does the following thing to send the JSON response to the API
private async void sendInvites_Click(object sender, RoutedEventArgs e)
{
var httpClient = new System.Net.Http.HttpClient();
System.Net.Http.HttpResponseMessage response;
var url = "https://graph.microsoft.com/v1.0/me/events";
CIBC.Models.SendMeetingInvites.RootObject obj = new CIBC.Models.SendMeetingInvites.RootObject();
CIBC.Models.SendMeetingInvites.Location loc = new CIBC.Models.SendMeetingInvites.Location();
loc.displayName = GlobalVariables.MeetingRoomName;
//loc.RoomEmailAddress = GlobalVariables.meetingRoomEmailID.ToString();
obj.subject = "Maths";
CIBC.Models.SendMeetingInvites.Body body = new CIBC.Models.SendMeetingInvites.Body();
body.content = "Its a booking for follow up meeting";
body.contentType = "HTML";
obj.body = body;
List<CIBC.Models.SendMeetingInvites.Attendee> attens = new List<Models.SendMeetingInvites.Attendee>();
for(int i=0;i<GlobalVariables.NumberOfParticipant.Count;i++)
{
CIBC.Models.SendMeetingInvites.EmailAddress email = new CIBC.Models.SendMeetingInvites.EmailAddress();
CIBC.Models.SendMeetingInvites.Attendee atten = new CIBC.Models.SendMeetingInvites.Attendee();
email.address = GlobalVariables.NumberOfParticipant[i].ParticipantADdress;
atten.emailAddress = email;
atten.type = "Required";
attens.Add(atten);
}
CIBC.Models.SendMeetingInvites.Start start = new CIBC.Models.SendMeetingInvites.Start();
start.dateTime = GlobalVariables.sendMeetingInviteStartDate;
start.timeZone = "UTC";
obj.start = start;
CIBC.Models.SendMeetingInvites.End end = new CIBC.Models.SendMeetingInvites.End();
end.dateTime = GlobalVariables.sendMeetingInviteEndTime;
end.timeZone = "UTC";
obj.end = end;
obj.attendees = attens;
obj.location = loc;
string postBody = Newtonsoft.Json.JsonConvert.SerializeObject(obj);
// var postBody1 = "{'Subject':'Testing Organizer - 12','Location':{'DisplayName':'Some place'}," +
//"'Start': {'DateTime': '2016-07-15T15:00:00.0000000', 'TimeZone':'UTC'}," +
//"'End': {'DateTime': '2016-07-15T15:30:00.0000000', 'TimeZone':'UTC'}," +
//"'Body':{'Content': 'This is a test of Grap API.', 'ContentType':'Text'}," +
//"'IsOrganizer':'False','Organizer':{'EmailAddress': " + "{'Address':'organizer#some.com'} }}";
// var requestString = #"{"subject":"My event","start":{"dateTime":"2017-09-25T07:44:27.448Z","timeZone":"UTC"},"end":{"dateTime":"2017-10-02T07:44:27.448Z","timeZone":"UTC"}}"";
var request = new System.Net.Http.HttpRequestMessage(System.Net.Http.HttpMethod.Post, url);
//Add the token in Authorization header
request.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer",GlobalVariables.Token);
request.Content = new StringContent(postBody, UTF8Encoding.UTF8, "application/json");
response = await httpClient.SendAsync(request);
if (response.IsSuccessStatusCode)
{ }
// return await response.Content.ReadAsStringAsync();
else
{
}
//return "";
}
Here is the class file that I am using to pass to the HTTPResponse Message
namespace CIBC.Models.SendMeetingInvites
{
public class Body
{
public string contentType { get; set; }
public string content { get; set; }
}
public class Start
{
public DateTime dateTime { get; set; }
public string timeZone { get; set; }
}
public class End
{
public DateTime dateTime { get; set; }
public string timeZone { get; set; }
}
public class Location
{
public string displayName { get; set; }
//public string RoomEmailAddress { get; set; }
}
public class EmailAddress
{
public string address { get; set; }
public string name { get; set; }
}
public class Attendee
{
public EmailAddress emailAddress { get; set; }
public string type { get; set; }
}
public class RootObject
{
public string subject { get; set; }
public Body body { get; set; }
public Start start { get; set; }
public End end { get; set; }
public Location location { get; set; }
public List<Attendee> attendees { get; set; }
}
}
My requirement is to send a meeting invite to all the users and also mentioning the Room Details like Name& Email ID of the room.
I tried adding a RoomEmail address in the Request as under The Location class
public string RoomEmailAddress { get; set; }
When I tested this using Microsoft Graph Explorer website , i got the error message
{
"error": {
"code": "RequestBodyRead",
"message": "The property 'RoomEmailAddress' does not exist on type 'Microsoft.OutlookServices.Location'. Make sure to only use
property names that are defined by the type or mark the type as open
type.",
"innerError": {
"request-id": "1883d87d-a5d6-4357-a699-7c112da0e56b",
"date": "2017-09-26T12:03:50"
}
} }
How do I make sure that whenever I create a meeting request , I can assign a room to it?
Currently I am just able to pass DisplayName while sending the Request to the URL.
Once I remove the Email Address property (I added myself ), the code returns Success.
Any workarounds so that I can send the room email address also so that the room also receives a copy of the meeting invite ?

Add the room as an attendee with "type": "Resource". Then add the room's display name in the location property.

Newtonsoft JSON deserialize using HttpWebResponse

I was searching in all the questions about deserialization with Newtonsfot Json Converter. But i wasn't able to find the problem in my code. So I put here, asking for help.
The message error from the visual studio:
No se controló Newtonsoft.Json.JsonSerializationException
HResult=-2146233088
Message=Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'APIEffilogics.Usuari+Client' because the type requires a
JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a
type that implements a collection interface (e.g. ICollection, IList)
like List that can be deserialized from a JSON array.
JsonArrayAttribute can also be added to the type to force it to
deserialize from a JSON array.
My JSON response is like this:
[ {
"id": 32,
"consultancy_id": 1,
"nif": "B61053922",
"contactname": "",
"email": "",
"phone": "",
"active": true,
"description": "Keylab" },
{
"id": 19,
"consultancy_id": 1,
"nif": "P0818300F",
"contactname": "Pau Lloret",
"email": "lloret#citcea.upc.edu",
"phone": "",
"active": true,
"description": "Rubi" } ]
And those are the classes:
namespace APIEffilogics
{
public class Usuari
{
public string access_token; //Encapsulat que conté la identificació de seguretat
public string token_type; //Tipus de token, "Bearer"
public string response; //Resposta de l'API

myReq.Headers.Set("Pragma", "no-cache");
myReq.Headers.Set("Authorization", usuari.token_type + " " + usuari.access_token);
if (metode.Equals("GET") || metode.Equals("POST"))
{
myReq.Method = metode; // Set the Method property of the request to POST or GET.
if (body == true)
{
// add request body with chat search filters
List<paramet> p = new List<paramet>();
paramet p1 = new paramet();
p1.value = "1";
string jsonBody = JsonConvert.SerializeObject(p1);
var requestBody = Encoding.UTF8.GetBytes(jsonBody);
myReq.ContentLength = requestBody.Length;
myReq.ContentType = "application/json";
using (var stream = myReq.GetRequestStream())
{
stream.Write(requestBody, 0, requestBody.Length);
}
body = false;
}
}
else throw new Exception("Invalid Method Type");
//Obtenim la resposta del servidor
HttpWebResponse myResponse = (HttpWebResponse)myReq.GetResponse();
Stream rebut = myResponse.GetResponseStream();
StreamReader readStream = new StreamReader(rebut, Encoding.UTF8); // Pipes the stream to a higher level stream reader with the required encoding format.
string info = readStream.ReadToEnd();
var jsondata = JsonConvert.DeserializeObject<Usuari.Client>(info);
myResponse.Close();
readStream.Close();*/
}
catch (WebException ex)
{
// same as normal response, get error response
var errorResponse = (HttpWebResponse)ex.Response;
string errorResponseJson;
var statusCode = errorResponse.StatusCode;
var errorIdFromHeader = errorResponse.GetResponseHeader("Error-Id");
using (var responseStream = new StreamReader(errorResponse.GetResponseStream()))
{
errorResponseJson = responseStream.ReadToEnd();
}
}
}
I don't know where is the problem, the response have the correct JSON scheme. Somebody can explain me where is the problem in my code, or if I'm not doing correctly.
I've solved the problem how you say, nut now I've a similar problem and the same message error. The JSON response now is this:
{
nodes: [
{
id: 5,
global_id: 5,
description: "Oven",
room_id: 2,
floor_id: 1,
building_id: 1,
client_id: 2,
nodemodel_id: 2,
nodetype_id: 1
},
{
id: 39,
global_id: 39,
description: "Fridge",
room_id: 2,
floor_id: 1,
building_id: 1,
client_id: 2,
nodemodel_id: 8,
nodetype_id: 1
}, ...
],
limit: 10,
offset: 0
}
And those are the classes:
public class Node : Usuari //Estructura nodes
{
[JsonProperty("limit")]
public int limit { get; set; }
[JsonProperty("offset")]
public int offset { get; set; }
[JsonProperty("nodes")]
public List<Node_sub> nodes_sub { get; set; }
}
public class Node_sub : Node
{
[JsonProperty("id")]
public string nid { get; set; }
[JsonProperty("global_id")]
public string gid { get; set; }
[JsonProperty("description")]
public string descrip { get; set; }
[JsonProperty("room_id")]
public string rid { get; set; }
[JsonProperty("floor_id")]
public string fid { get; set; }
[JsonProperty("client_id")]
public string cid { get; set; }
[JsonProperty("building_id")]
public string bid { get; set; }
[JsonProperty("nodemodel_id")]
public string model { get; set; }
[JsonProperty("nodetype_id")]
public string type { get; set; }
}
The code is the same as before, only I add this sentences:
jsonnode = JsonConvert.DeserializeObject<List<Usuari.Node>>(info);
Why I'm having the same error? List<Usuari.Node> is an array that contains all the items of JSON message.
Thanks

Try
var jsondata = JsonConvert.DeserializeObject<List<Usuari.Client>>(info);
This addresses the issue as the exception suggests:
To fix this error either change the JSON to a JSON object (e.g.
{"name":"value"}) or change the deserialized type to an array or a
type that implements a collection interface (e.g. ICollection, IList)
like List that can be deserialized from a JSON array
Emphasis added to highlight the salient point
The HTTP response you receive is an array of objects so you need to deserialise it in a way that can deal with an array of objects. By changing your code to deserialise into a List<Usari.Client> you do just that and it should resolve the error.

I am using JSON.Net and everything is working fine but in some of my data some element fields are missing for example i am getting Team element inside Competitors as
Teams = from JObject comps in value["Competitors"]["Competitors"]
select (string)comps["Team"]
But in some data Team element is missing and i want to grap Name Element so i am getting Object reference not set to an instance of an object. Error.
This is my code
var query =
from JProperty ev in obj.AsJEnumerable()
from JProperty evid in ev.Value.AsJEnumerable()
let value = (JObject)evid.Value
select new Person
{
EventID = (string)value["EventID"],
Description = (string)value["MainEvent"],
OutcomeDateTime = (string)value["OutcomeDateTime"],
EventStatus = (string)value["EventStatus"],
Teams = from JObject comps in value["Competitors"]["Competitors"]
select (string)comps["Team"]
};
foreach (var b in query)
{
string description = b.Description;
string OutcomeDateTime = b.OutcomeDateTime;
IEnumerable<string> _team = b.Teams;
foreach (var teams in _team)
{
string team = teams.ToString();
}
Console.WriteLine(description);
Console.WriteLine(OutcomeDateTime);
}
How can i get Name element value if Team element does not exist ?

You can deserialize your json to concrete classes
var obj = JsonConvert.DeserializeObject < Dictionary<string, Dictionary<string,RootObject>>>(json);
public class Competitor
{
public string Team { get; set; }
public string Win { get; set; }
}
public class CompetitorsClass
{
public int ActiveCompetitors { get; set; }
public List<Competitor> Competitors { get; set; }
public int TotalCompetitors { get; set; }
public bool HasWinOdds { get; set; }
}
public class RootObject
{
public int EventID { get; set; }
public int ParentEventID { get; set; }
public string MainEvent { get; set; }
public CompetitorsClass Competitors { get; set; }
public string EventStatus { get; set; }
public bool IsSuspended { get; set; }
public bool AllowBets { get; set; }
}
BTW: What is OutcomeDateTime? there is no such field in your json.

The following will work. Use the null-coalescing operator to grab "Name" if "Team" is null. http://msdn.microsoft.com/en-us/library/ms173224.aspx
Teams = from JObject comps in value["Competitors"]["Competitors"]
select (string)comps["Team"] ?? (string)comps["Name"]
