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

A good way to use JSON in C# is with [JSON.NET][1]

[Quick Starts & API Documentation][2] from [JSON.NET - Official site][3] 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);
}

Using `JavaScriptSerializer()` is less strict than the generic solution offered :

public static T Deserialize<T>(string json)

That might come handy when passing json to the server that does not match exactly the Object definition you are trying to convert to.

Rather than sending as just an object, create a public class of properties that is accessible and send the data to the Webmethod.

[WebMethod]
public static void SaveTeam(useSomeClassHere user)
{
}

Use the same parameters names in the Ajax call to send the data.

Another *really* simple solution is using the library Newtonsoft.Json:

User user = JsonConvert.DeserializeObject<User>(jsonString);
