How to deserialize an array of JSON in C#? [duplicate]

Question

I have received the following json at my client application:

[{
    "ErrorCode" : 0,
    "ErrorMessage" : "The operation completed successfully."
}, {
    "configured" : true,
    "id" : "abc"
}]

Properties ErrorCode and ErrorMessage belong to the ErrorInfo-class and the properties configured and id belong to the Data-class.

I need to deserialize this JSON so that I can populate these two classes ErrorInfo and Data. How can I deserialize this json code to C#?

I'd use Json.NET... do you already have a class representing the objects? Do you want to access them dynamically? Have you tried anything yourself yet? — Jon Skeet

its not duplicate .. it is kind of array of jsons which belongs to different classes.. — Pooja Kuntal

So how do you expect anything to know which class to deserialize which object as? It sounds like you should probably use LINQ to JSON instead. — Jon Skeet

You can install the NuGet packet Newtonsoft And use the class JsonConvert. An example:

string json = @"{
  'Name': 'Bad Boys',
  'ReleaseDate': '1995-4-7T00:00:00',
  'Genres': [
    'Action',
    'Comedy'
  ]
}";

Movie m = JsonConvert.DeserializeObject<Movie>(json);

Make also a class Movie whit the same properties and types.
