How to serialize a multiple list of elements in Json? - c#

I have a JSON that looks like this:
{
"Identifier1":"TextOfIdentifier1",
"Identifier2":"TextOfIdentifier2",
"Identifier3":"TextOfIdentifier3",
...
}
I know how to deseralize a JSON into a custom object, I followed what says here, but all identifiers appear in the same JSON tag...
How can I get all identifiers inside the JSON?

The solution is like this in my case:
using (StreamReader r = new StreamReader(path))
{
string json = r.ReadToEnd();
JObject jsonLines = JObject.Parse(json);
foreach (var token in jsonLines)
{
dtos.Add(new TokenDto { HalId = token.Key, SourceText = token.Value.ToString() });
}
}

You can traverse JSON (similar to XDocument):
var json = "{\"Identifier1\":\"TextOfIdentifier1\",\"Identifier2\":\"TextOfIdentifier2\",\"Identifier3\":\"TextOfIdentifier3\"}";
foreach (var token in JObject.Parse(json).Children())
Console.WriteLine(token.Path);
Result:
Identifier1
Identifier2
Identifier3

Add property to each object in JSON C#

I have a JSON body which looks like this(an array of objects):
[
{
"registered": "2016-02-03T07:55:29",
"color": "red",
},
{
"registered": "2016-02-03T17:04:03",
"color": "blue",
}
]
This body is contained in a variable(requestBody) I create based on a HTTP Request, it's called req:
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
What I want to do is add a unique identifier to each one of the objects in my JSON array. How could I go about achieving this?
Currently I am deserializing the JSON, adding some string(x) to it and then serializing it again:
dynamic d = JsonConvert.DeserializeObject(requestBody);
d.uniqueId = "x";
string newBody = JsonConvert.SerializeObject(d);
I was to add a uniqueId to each one of the objects in my JSON array of objects. How could I achieve this?
You can use JArray from LINQ to JSON API to parse, iterate children of JObject type and modify them:
var json = ...; // your json string
var jArray = JArray.Parse(json);
foreach (var jObject in jArray.Children<JObject>())
{
jObject.Add("id", new JValue("x"));
}
var modified = JsonConvert.SerializeObject(jArray);

Json Array Parsing

I am using NewtonSoft to try to parse a jSON array in C# Winform solution. Can anyone help me figure out how to do this?
["yahoo!",["yahoo mail","yahoo finance","yahoo news","yahoo mail login","yahoo sports","yahoo fantasy football","yahoo fantasy","yahoo india","yahoo groups","yahoo search"]]
string json = Helpers.GetGoogleSuggestionKeyword("Yahoo!").ToString();
JArray GoogleSuggesionKeywordResult = JArray.Parse(json);
foreach (JObject item in GoogleSuggesionKeywordResult)
{
// MessageBox.Show(item.ToString());
}
//var json = "[\"yahoo!\",[\"yahoo mail\",\"yahoo finance\",\"yahoo news\",\"yahoo mail login\",\"yahoo sports\",\"yahoo fantasy football\",\"yahoo fantasy\",\"yahoo india\",\"yahoo groups\",\"yahoo search\"]]";
string json = Helpers.GetGoogleSuggestionKeyword("Yahoo!").ToString();
JArray GoogleSuggesionKeywordResult = JArray.Parse(json);
//JArray GoogleSuggesionKeywordResult = JsonConvert.DeserializeObject<JArray>(json);
foreach (JToken item in GoogleSuggesionKeywordResult[1])
{
Console.WriteLine((string)item);
}
i have used JArray & JsonConverter. Which method you preferred you can use it

Removing an element from a JSON response

I have a JSON string from which I want to be able to delete some data.
Below is the JSON response:
{
"ResponseType": "VirtualBill",
"Response": {
"BillHeader": {
"BillId": "7134",
"DocumentId": "MN003_0522060",
"ConversionValue": "1.0000",
"BillType": "Vndr-Actual",
"AccountDescription": "0522060MMMDDYY",
"AccountLastChangeDate": "06/07/2016"
}
},
"Error": null
}
From above JSON response I want to able remove the
"ResponseType": "VirtualBill", part such that it looks like this:
{
"Response": {
"BillHeader": {
"BillId": "7134",
"DocumentId": "MN003_0522060",
"ConversionValue": "1.0000",
"BillType": "Vndr-Actual",
"AccountDescription": "0522060MMMDDYY",
"AccountLastChangeDate": "06/07/2016"
}
},
"Error": null
}
Is there an easy way to do this in C#?
Using Json.Net, you can remove the unwanted property like this:
JObject jo = JObject.Parse(json);
jo.Property("ResponseType").Remove();
json = jo.ToString();
Fiddle: https://dotnetfiddle.net/BgMQAE
If the property you want to remove is nested inside another object, then you just need to navigate to that object using SelectToken and then Remove the unwanted property from there.
For example, let's say that you wanted to remove the ConversionValue property, which is nested inside BillHeader, which is itself nested inside Response. You can do it like this:
JObject jo = JObject.Parse(json);
JObject header = (JObject)jo.SelectToken("Response.BillHeader");
header.Property("ConversionValue").Remove();
json = jo.ToString();
Fiddle: https://dotnetfiddle.net/hTlbrt
Convert it to a JsonObject, remove the key, and convert it back to string.
Sample sample= new Sample();
var properties=sample.GetType().GetProperties().Where(x=>x.Name!="ResponseType");
var response = new Dictionary<string,object>() ;
foreach(var prop in properties)
{
var propname = prop.Name;
response[propname] = prop.GetValue(sample); ;
}
var response= Newtonsoft.Json.JsonConvert.SerializeObject(response);

How can i access any key inside of json string via C#?

My question is simple but i can not do that. i wanna get value of "soap:Body" from below string by C#code?
{"soap:Envelope":{"xmlns:xsd":"http://www.w3.org/2001/XMLSchema","xmlns:soap":"http://www.w3.org/2003/05/soap-envelope","xmlns:xsi":"http://www.w3.org/2001/XMLSchema-instance","soap:Body":{"ToplamaResponse":{"xmlns":"http://tempuri.org/","ToplamaResult":156758}}}}
You can also use the Framework class JavaScriptSerializer if you do not want to use an external library.
string json = #"...";
JavaScriptSerializer serializer = new JavaScriptSerializer();
var o = serializer.Deserialize<dynamic>(json);
var body = o["soap:Envelope"]["soap:Body"];
You can do it easily by using Json.NET
dynamic data = JObject.Parse("{'soap:Envelope':{'xmlns:xsd':'http://www.w3.org/2001/XMLSchema','xmlns:soap':'http://www.w3.org/2003/05/soap-envelope','xmlns:xsi':'http://www.w3.org/2001/XMLSchema-instance','soap:Body':{'ToplamaResponse':{'xmlns':'http://tempuri.org/','ToplamaResult':156758}}}}");
string soap_body = data["soap:Envelope"]["soap:Body"];
There is a simple example in the JObject.Parse documentation
string json = #"{
"soap:Envelope": {
"xmlns:xsd": "http://www.w3.org/2001/XMLSchema",
"xmlns:soap": "http://www.w3.org/2003/05/soap-envelope",
"xmlns:xsi": "http://www.w3.org/2001/XMLSchema-instance",
"soap:Body": {
"ToplamaResponse": {
"xmlns": "http://tempuri.org/",
"ToplamaResult": 156758
}
}
}
}";
JObject obj = JObject.Parse(json);
Console.WriteLine((string)obj["soap:Envelope"]["soap:Body"]);
And if you want to manipulate the value of "soap:Body" do the same thing :)

How to list a newtonsoft Jtoken or JObjects children in a listBox

I have a json file that i read to string and then convert to a jobject. I get a JToken from this object by selecting one of its children.
I want to list this JTokens children in a Listbox. I think, to do this i need to convert th eJTOken to a ListItem - how can i do this? If there is a better alternative way then would be interested to hear it!
string filePath = #"C:\output.json";
JObject json = JObject.Parse(System.IO.File.ReadAllText(filePath));
JToken jsonFiles = json["Files"];
jsonFilesListItem = ....
JsonListBox.Items.Add(jsonFilesListItem);
Assuming that json["Files"] contains a simple array of strings, all you have to do is use a foreach loop, as shown in the example below:
string jsonString = #"
{
""Files"": [
""foo.xml"",
""bar.txt"",
""baz.jpg"",
""quux.wav""
]
}";
JObject json = JObject.Parse(jsonString);
JToken jsonFiles = json["Files"];
foreach (string fileName in jsonFiles)
{
JsonListBox.Items.Add(fileName);
}
