Trying best how to take the following classes and deserialize a Json file to return each class values back to Simpl+. I am able to receive the Total value but anything in a list I am at a lost.
public class Client
{
public string clientId { get; set; }
public string locale { get; set; }
public string location { get; set; }
public string auxiliaryId { get; set; }
public string description { get; set; }
public string type { get; set; }
public string typeDescription { get; set; }
public Hardware hardware { get; set; }
public Network network { get; set; }
}
public class Hardware
{
public string type { get; set; }
public string softwareVersion { get; set; }
public string serialNumber { get; set; }
public string hardwareVersion { get; set; }
public string model { get; set; }
}
public class Network
{
public string ip { get; set; }
public string mac { get; set; }
public object homepage { get; set; }
public string dhcpSubnet { get; set; }
}
public class Result
{
public List<Client> clients { get; set; }
public string total { get; set; }
public int limit { get; set; }
public int page { get; set; }
}
public class Root
{
public string jsonrpc { get; set; }
public object id { get; set; }
public Result result { get; set; }
}
I was able to resolve this by adding the following to the foreach statement:
args.MyIndex = (ushort)(rootObject.TriplePlayResult.clients.IndexOf(item) + 1);
I have some problems deserializing the following JSON string. On all of my other responses it works really good but not for this one. I tried so many different things and I checked the Stream class about 100 times. I also have used a generated class from json2csharp but all my deserialized Data is NULL.
My code to get the response:
public Stream getStream(string userID)
{
var request = GetRequest("streams/{channelID}", Method.GET);
request.AddUrlSegment("channelID", userID);
var response = restClient.Execute<Stream>(request);
return response.Data;
}
response.Content shows me as example something like that:
{
"stream":
{
"_id":25649270464,
"game":"test",
"broadcast_platform":"other",
"community_id":"xxxxxxxxx",
"community_ids":["xxxxxx"],

1) use JSON Utils (https://jsonutils.com/) to generate your C# classes (for attributes select JsonProperty)
2) Newtonsoft.Json is pretty much the standard best library to work with JSON formats in .NET, you can get it from nuget.
3) The code should look something like this, and deserialization should work without any problems:
class Program
{
private static void Main(string[] args)
{
var myObj = JsonConvert.DeserializeObject<JsonDef>(json);
Console.Read();
}

}
It's because of the DateTime format of the JSON. It is not in a well-formed .Net DateTime. so you can get it as a string and then convert it the way you want or change its format into a readable .Net one.
I made a code for deserialize this JSON
First of all, I've created a class:
public class Self
{
public string href { get; set; }
}
public class Soccerseason
{
public string href { get; set; }
}
public class HomeTeam
{
public string href { get; set; }
}
public class AwayTeam
{
public string href { get; set; }
}
public class Links
{
public Self self { get; set; }
public Soccerseason soccerseason { get; set; }
public HomeTeam homeTeam { get; set; }
public AwayTeam awayTeam { get; set; }
}
public class Result
{
public int goalsHomeTeam { get; set; }
public int goalsAwayTeam { get; set; }
}
public class LastHomeWinHomeTeam
{
public Links _links { get; set; }
public string date { get; set; }
public object status { get; set; }
public int matchday { get; set; }
public string homeTeamName { get; set; }
public string awayTeamName { get; set; }
public Result result { get; set; }
}
public class LastWinHomeTeam
{
public Links _links { get; set; }
public string date { get; set; }
public object status { get; set; }
public int matchday { get; set; }
public string homeTeamName { get; set; }
public string awayTeamName { get; set; }
public Result result { get; set; }
}
public class LastAwayWinAwayTeam
{
public Links _links { get; set; }
public string date { get; set; }
public object status { get; set; }
public int matchday { get; set; }
public string homeTeamName { get; set; }
public string awayTeamName { get; set; }
public Result result { get; set; }
}
public class LastWinAwayTeam
{
public Links _links { get; set; }
public string date { get; set; }
public object status { get; set; }
public int matchday { get; set; }
public string homeTeamName { get; set; }
public string awayTeamName { get; set; }
public Result result { get; set; }
}
public class Head2head
{
public int count { get; set; }
public string timeFrameStart { get; set; }
public string timeFrameEnd { get; set; }
public int homeTeamWins { get; set; }
public int awayTeamWins { get; set; }
public int draws { get; set; }
public LastHomeWinHomeTeam lastHomeWinHomeTeam { get; set; }
public LastWinHomeTeam lastWinHomeTeam { get; set; }
public LastAwayWinAwayTeam lastAwayWinAwayTeam { get; set; }
public LastWinAwayTeam lastWinAwayTeam { get; set; }
public List<Fixture> fixtures { get; set; }
}
public class Fixture
{
public Links _links { get; set; }
public string date { get; set; }
public object status { get; set; }
public int matchday { get; set; }
public string homeTeamName { get; set; }
public string awayTeamName { get; set; }
public Result result { get; set; }
}
public class RootObject
{
public List<Fixture> fixture { get; set; }
public Head2head head2head { get; set; }
}
So I made a code for parsing a request, and return a responseText:
string responseText = Parser.Request(link); //Parser is the class that perform HttpRequest
so far no problem.
I've declarated the object for deserialize the responseText returned:
var obj = JsonConvert.DeserializeObject<Fixtures.RootObject>(responseText);
and next I do the foreach:
foreach (var fixture in obj.fixture)
{do stuff..}
but in obj.fixture I get null and I don't know why. Because all JSON is deserialized correcly. What am I doing wrong?
The key in the JSON is "fixtures" - it needs to match the property name of your class exactly. Change
public List<Fixture> fixture { get; set; }
to
public List<Fixture> fixtures { get; set; }
Alternatively, you can use the JsonProperty attribute:
[JsonProperty("fixtures")]
public List<Fixture> fixture { get; set; }
I am getting the following exception when I try to deserialize a JSON response from Twitter API. It sometime went through but sometime have an issue.

public string Message { get; set; }
[JsonProperty(PropertyName = "id")]
public object ID { get; set; }
[JsonProperty(PropertyName = "created_at")]
public DateTime TwitTime { get; set; }
}
And I try to deserialize the response in the following way:
string str = TwitterAPI(Request.QueryString["screen_name"].ToString(), "10");
var root = JsonConvert.DeserializeObject<List<RootObject>>(str);
Where TwitterAPI() will return the response from following Twitter API:
https://api.twitter.com/1.1/statuses/user_timeline.json
Below is the detailed error:
I just found an answer.
The issue was with the limitations of Twitter API as the documentation says:
"When an application exceeds the rate limit for a given API endpoint, the Twitter API will now return an HTTP 429 error"
and I was exceeding the limit so it was giving an exception (429) Too Many Requests.
If you hit the rate limit on a given endpoint, this is the body of the HTTP 429 message that you will see:
{
"errors": [
{
"code": 88,
"message": "Rate limit exceeded"
}
]
}
So it was returning only an error message in JSON format and it was passing it to Deserialize function which in turn giving that error.
Thanks all for your suggestions.
I'm getting the following exception when using this bit of code to deserialize a JSON response from CrunchBase. The weird thing is it only happens to certain pages that are being deserialized even though both the results that work fine and the ones that don't both have empty [], empty"", and null values in key:value pairs. How can I cast or correct my mistake?
Exception gets thrown here:
JsonSerializer serializer = new JsonSerializer();
RootObject ro = JsonConvert.DeserializeObject<RootObject>(response);
The inner exception is:
InnerException:
Message=Could not cast or convert from {null} to System.Int32.
Source=Newtonsoft.Json
Thanks for your eyes in advance!
Update:
as asked for the structure of the root object and the additional objects on that JSON endpoint. These were generated by http://json2csharp.com/ after putting the URL of the JSON endpoint into it.
The JSON is long so here are two example links: this one works without error http://api.crunchbase.com/v/1/company/kiip.js , while this other (and others) throws the exception http://api.crunchbase.com/v/1/company/tata-communications.js

Json.NET supports JSON Schema. You could create a schema with all the required properties marked and validate incoming JSON against it before deserializing. In this you can check if value is null you can make change it to some default value.
Hope this works for you.
