public static T JSONToObj<T>(string i_json)
{
    var serializer = new JavaScriptSerializer();
    T io_obj = serializer.Deserialize<T>(i_json);

    return io_obj;
}

You can call it like this:

Home h = JSONToObj<Home>(json);

and how should i call this method ?

Yuval Itzchakov Over a year ago

@dotnetom You need to add a constraint where T : new() for the type to be deserializable

Updated types. You can't return an object for type T.

@YuvalItzchakov If that were the case, wouldn't the Deserialize method have that same constraint? But it doesn't: msdn.microsoft.com/en-us/library/bb355316(v=vs.110).aspx

@YuvalItzchakov - If Deserialize had new() restriction, then the same restriction would be required here
