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.

How to get data from json api with c# using httpwebrequest?

I want to get all variables from https://api.coinmarketcap.com/v1/ticker/ in my c# console application.
How can I do this?
I started with getting the whole page as a stream. What to do now?
private static void start_get()
{
HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create
(string.Format("https://api.coinmarketcap.com/v1/ticker/"));
WebReq.Method = "GET";
HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
Console.WriteLine(WebResp.StatusCode);
Console.WriteLine(WebResp.Server);
Stream Answer = WebResp.GetResponseStream();
StreamReader _Answer = new StreamReader(Answer);
Console.WriteLine(_Answer.ReadToEnd());
}

First you need a custom class to use for deserialization:
public class Item
{
public string id { get; set; }
public string name { get; set; }
public string symbol { get; set; }
public string rank { get; set; }
public string price_usd { get; set; }
[JsonProperty(PropertyName = "24h_volume_usd")] //since in c# variable names cannot begin with a number, you will need to use an alternate name to deserialize
public string volume_usd_24h { get; set; }
public string market_cap_usd { get; set; }
public string available_supply { get; set; }
public string total_supply { get; set; }
public string percent_change_1h { get; set; }
public string percent_change_24h { get; set; }
public string percent_change_7d { get; set; }
public string last_updated { get; set; }
}
Next, you can use Newtonsoft Json, a free JSON serialization and deserialization framework in the following way to get your items (include the following using statements):
using System.Net;
using System.IO;
using Newtonsoft.Json;
private static void start_get()
{
HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(string.Format("https://api.coinmarketcap.com/v1/ticker/"));
WebReq.Method = "GET";
HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
Console.WriteLine(WebResp.StatusCode);
Console.WriteLine(WebResp.Server);
string jsonString;
using (Stream stream = WebResp.GetResponseStream()) //modified from your code since the using statement disposes the stream automatically when done
{
StreamReader reader = new StreamReader(stream, System.Text.Encoding.UTF8);
jsonString = reader.ReadToEnd();
}
List<Item> items = JsonConvert.DeserializeObject<List<Item>>(jsonString);
Console.WriteLine(items.Count); //returns 921, the number of items on that page
}
Finally, the list of elements is stored in items.

A simplified version of Keyur PATEL's work.
static void GetCoinValues()
{
string json = new WebClient().DownloadString("https://api.coinmarketcap.com/v1/ticker/");
List<Item> items = JsonConvert.DeserializeObject<List<Item>>(json);
foreach (var item in items)
{
Console.WriteLine("ID: " + item.id.ToUpper());
Console.WriteLine("Name: " + item.name.ToUpper());
Console.WriteLine("Symbol: " + item.symbol.ToUpper());
Console.WriteLine("Rank: " + item.rank.ToUpper());
Console.WriteLine("Price (USD): " + item.price_usd.ToUpper());
Console.WriteLine("\n");
}
}

While trying to upload video using daily motion API i got this error "The request was aborted: The request was canceled."

i am using daily motion API for uploading videos from my application but when try to upload more than 2 MB sized video i get this error "The request was aborted: The request was canceled." and this error invoked by this line of code var responseBytes = client.UploadFile(uploadUrl, fileToUpload);
and this is my code which i am using to upload video
public static void Main(MyVideo video)
{
var accessToken = GetAccessToken();
Authorize(accessToken);
var fileToUpload = video.Path;
var uploadUrl = GetFileUploadUrl(accessToken);
var response = GetFileUploadResponse(fileToUpload, accessToken, uploadUrl);
var uploadedResponse = PublishVideo(response, accessToken);
}
public class UploadResponse
{
public string format { get; set; }

Using the Constant Contact C# .net-sdk v2 to create/add

I'm using the official version 2 of the Constant Contact .net-sdk found here.
I've been unable to find methods for the following:
Creating a Contact List
Adding a contact to a Contact List
Removing a contact from a Contact List
Adding multiple contacts to a Contact List
Creating an Email Campaign
These features clearly exist in v2 of the API found here, but seem missing from the SDK.
Any help in accessing this functionality is appreciated.

Create Contact.
try
{
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "<Replace with your oAuth Token>");
ContactObject cont = new ContactObject
{
first_name = "Deepu",
last_name = "Madhusoodanan"
};
var email_addresses = new List<EmailAddress>
{
new EmailAddress{email_address = "deepumi1#gmail.com"}
};
cont.email_addresses = email_addresses;
cont.lists = new List<List>
{
new List {id = "<Replace with your List Id>"}
};
var json = Newtonsoft.Json.JsonConvert.SerializeObject(cont);
string MessageType = "application/json";
using (var request = new HttpRequestMessage(System.Net.Http.HttpMethod.Post, "https://api.constantcontact.com/v2/contacts?api_key=<Replace with your API key>"))
{
request.Headers.Add("Accept", MessageType);
request.Content = new StringContent(json);
request.Content.Headers.ContentType = System.Net.Http.Headers.MediaTypeHeaderValue.Parse(MessageType);
using (var response = await client.SendAsync(request).ConfigureAwait(false))
{
string responseXml = await response.Content.ReadAsStringAsync().ConfigureAwait(false);
var code = response.StatusCode;
}
request.Content.Dispose();
}
}
}
catch (Exception exp)
{
//log exception here
}
/*Model class*/
public class Address
{
public string address_type { get; set; }
public string city { get; set; }
public string country_code { get; set; }

public string line2 { get; set; }
public string line3 { get; set; }
public string postal_code { get; set; }

public string last_name { get; set; }
public string middle_name { get; set; }
public string prefix_name { get; set; }
public string work_phone { get; set; }
}
Note : You have to replace oAuth token, API key and List id.
Delete method based on the api document.(http://developer.constantcontact.com/docs/contacts-api/contacts-resource.html?method=DELETE)
Note : I have not tested the delete method yet.
private async Task<string> DeleteContact(string contactId)
{
try
{
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "<Replace with your oAuth Token>");
using (var request = new HttpRequestMessage(System.Net.Http.HttpMethod.Delete, "https://api.constantcontact.com/v2/contacts/" + contactId + "?api_key=<Replace with your API key>"))
{
using (var response = await client.SendAsync(request).ConfigureAwait(false))
{
response.EnsureSuccessStatusCode();
return await response.Content.ReadAsStringAsync().ConfigureAwait(false);
}
}
}
}
catch (Exception exp)
{
//log exp here
}
return string.Empty;
}

Here is my solution for adding a contact. What I did was combine the code that Deepu provided with the Constant Contact API v2. I also had to remove async and await references because they are incompatible with VS2010. I have not tried DELETE yet...

Incorrect JSON Date

I am having trouble with the representation of a date in JSON. I am using Service Stack as a web service to get the data from. My code on the server side is as follows:
public object Execute(GetNoPatientList request)
{
NoPatientList _noPatientList = new NoPatientList();
List<string> _noMatchPatientList = new List<string>();
List<NoPatientList> _newList = new List<NoPatientList>();
try
{
using (SqlConnection cn = new SqlConnection(Database.WaldenWebConnection))
{
cn.Open();
using (SqlCommand cm = cn.CreateCommand())
{
cm.CommandText = "select [DateTimeStamp] as DateCreated,[ID],[PatientMRN],[FirstName],[MiddleName]"
+ " ,[LastName],convert(varchar,[DOB],101) as DOB,[Sex],[Note],[Source] as Interface"
+ " from PatientNoMatch"
+ " where FoundMatch = 'F'"
+ " and Show = 'T'"
+ " order by DateTimeStamp desc";
SqlDataReader dr = cm.ExecuteReader();
while (dr.Read())
{
NoPatientList _noPatientList1 = new NoPatientList();
_noPatientList1.PatientMRN = dr["PatientMRN"].ToString();
_noPatientList1.FirstName = dr["FirstName"].ToString();
_noPatientList1.MiddleName = dr["MiddleName"].ToString();
_noPatientList1.LastName = dr["LastName"].ToString();
_noPatientList1.DOB = dr["DOB"].ToString();
_noPatientList1.Sex = dr["Sex"].ToString();
_noPatientList1.Note = dr["Note"].ToString();
_noPatientList1.DateCreated = dr.GetDateTime(0);
_noPatientList1.Interface = dr["Interface"].ToString();
_newList.Add(_noPatientList1);
}
return _newList;
}
}
}
catch
{
return _newList;
}
}
The type is represented as follows:
[DataContract]
public class NoPatientList
{
[DataMember]
public string ID { get; set; }
[DataMember]
public string PatientMRN { get; set; }
[DataMember]
public string FirstName { get; set; }
[DataMember]
public string MiddleName { get; set; }
[DataMember]
public string LastName { get; set; }
[DataMember]
public string Sex { get; set; }
[DataMember]
public string DOB { get; set; }
[DataMember]
public string Note { get; set; }
[DataMember]
public DateTime DateCreated { get; set; }
[DataMember]
public string Interface { get; set; }
}
The web service is being consumed by a Silverlight application from the following call:
/InterfaceUtility/servicestack/json/syncreply/
The Silverlight application is processing the code into a grid using the following code
private void GetNoPatientMatchData()
{
try
{
gridViewNoMatch.ItemsSource = null;
}
catch { }
_client = new WebClient();
_client.OpenReadCompleted += (a, f) =>
{
if (!f.Cancelled && f.Error == null)
{
_listOfNoPatientsMatches = new List<NoPatientList>();
MemoryStream _memoryStream = new MemoryStream();
f.Result.CopyTo(_memoryStream);
_memoryStream.Position = 0;
StreamReader _streamReader = new StreamReader(_memoryStream);
string _memoryStreamToText = _streamReader.ReadToEnd();
List<NoPatientList> _deserializedNoPatientList = (List<NoPatientList>)Newtonsoft.Json.JsonConvert.DeserializeObject(_memoryStreamToText, typeof(List<NoPatientList>));
gridViewNoMatch.ItemsSource = _deserializedNoPatientList;
}
else
{
MessageBox.Show(f.Error.Message,
"Error", MessageBoxButton.OK);
}
};
_client.OpenReadAsync(new Uri(_serviceUri + "getnopatientlist"));
The issue is that the times on DateTime field appear to always 6 hours off.
Any ideas as to what is going on?

This is probably a time zone issue. Check that:
Your webservice is returning you dates/times in UTC format.
Your code is parsing these dates/times as UTC dates and times.
