Deserialize JSON string to c# object

I think the JavaScriptSerializer does not create a dynamic object.

So you should define the class first:

class MyObj {
    public int arg1 {get;set;}
    public int arg2 {get;set;}
}

And deserialize that instead of object:

serializer.Deserialize<MyObj>(str);

Not testet, please try.

Use this code:

var result=JsonConvert.DeserializeObject<List<yourObj>>(jsonString);

I believe you are looking for this:

string str = "{\"Arg1\":\"Arg1Value\",\"Arg2\":\"Arg2Value\"}";
JavaScriptSerializer serializer1 = new JavaScriptSerializer();
object obje = serializer1.Deserialize(str, obj1.GetType());
