How can I connvert a JSON object to a custom C# object?

.net, ajax, asp.net, c#, json

Solution

A good way to use JSON in C# is with JSON.NET

Quick Starts & API Documentation from JSON.NET - Official site help you work with it.

An example of how to use it:

public class User
{
    public User(string json)
    {
        JObject jObject = JObject.Parse(json);
        JToken jUser = jObject["user"];
        name = (string) jUser["name"];
        teamname = (string) jUser["teamname"];
        email = (string) jUser["email"];
        players = jUser["players"].ToArray();
    }

    public string name { get; set; }
    public string teamname { get; set; }
    public string email { get; set; }
    public Array players { get; set; }
}

// Use
private void Run()
{
    string json = @"{""user"":{""name"":""asdf"",""teamname"":""b"",""email"":""c"",""players"":[""1"",""2""]}}";
    User user = new User(json);

    Console.WriteLine("Name : " + user.name);
    Console.WriteLine("Teamname : " + user.teamname);
    Console.WriteLine("Email : " + user.email);
    Console.WriteLine("Players:");

    foreach (var player in user.players)
        Console.WriteLine(player);
 }

Problem

Is there an easy way to populate my C# object with the JSON object passed via AJAX? This is the JSON object passed to a C# web method from the page using JSON.stringify: ``` { "user": { "name": "asdf", "teamname": "b", "email": "c", "players": ["1", "2"] } } ``` The C# web method that receives the JSON object: ``` [WebMethod] public static void SaveTeam(Object user) { } ``` The C# class that represents the object structure of JSON Object passed in to the web method ``` public class User { public string name { get; set; } public string teamname { get; set; } public string email { get; set; } public Array players { get; set; } } ```
