Deserialize JSON Objects in Asp.Net MVC Controller

Question

I'm trying to deserialize an object which was generated by LinqToSql. The user is allowed to edit the data of the object in the view and then it gets posted back to the controller. The edited Data comes in JSON. How does this action have to look like?

Something like...

public ActionResult(JsonObject json)
{
    MyClass c = Jsonify(json) as MyClass;
}

Is there a nice helpful static class in the framework I'm missing? Or do I have to create a DataContract?

Many thanks

System.Web.Script.Serialization.JavaScriptSerializer

public ActionResult Blah(JsonObject json)
{
    JavaScriptSerializer js = new JavaScriptSerializer();
    var c = js.Deserialize<MyClass>(json);
    return View(c);
}

EDIT: Oops...just noticed you are passing an object instead of string....so you will need to use System.Runtime.Serialization.Json.DataContractJsonSerializer:

DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(MyClass));
MyClass c = (MyClass)serializer.ReadObject(json);

Seems to me the DataContractJsonSerializer's ReadObject method only accepts XML readers or streams as input? – Ted Nyberg Sep 20 '13 at 16:53
@TedNyberg Yes, that is true: http://msdn.microsoft.com/en-us/library/bb908232.aspx – Bradley Mountford Sep 23 '13 at 16:59
What would be the .NET 5 approach to this? – spencer741 Feb 13 '21 at 02:11
