What's wrong?
How 'error' declared?
Why not to read the documentation?

can you show your c# class against the json you created?

Your c# classes structure would be like :

C#

public class Error
{
    public string id { get; set; }
    public string code { get; set; }
    public string message { get; set; }
}

public class RootObject
{
    public List<Error> error { get; set; }
}

and now you have to write in api:

C#

RootObject obj =JsonConvert.DeserializeObject<RootObject>(jsonString);

You can always use online tools like json2csharp.comto get the c# classes structure against the json.

There are some typos in your code.

Ehsan Sajjad 4-May-16 6:54am

for example ??

For example the errors you corrected.
public List<Error> error { get; set; }
used to be
public List<error> error { get; set; }

(Not easy to write code in comments)

oh, i corrected it, i noticed that after adding the reply to your comment. Thanks for pointing out :)

}

public class MyErrorDetail
{
    public string id;
