Question

I am building on Windows Phone 7. I noticed in the documentation I can:

JsonObject user = (JsonObject)JsonObject.Load(responseStream);
bool isMember = user["IsMember"];
string name = user["Name"];
int age = user["Age"];

How can I import the JsonObject class?

Answer 1

Add using System.Json; to the top of your file.

Edit
It seems that Windows Phone 7 doesn’t support the System.Json namespace so you cannot do it this way. After a cursory search, it seems you have to use the DataContractJsonSerializer class as shown in this MSDN video/source code.

You may also want to consider using Json.NET which appears to be much more efficient than the DataContractJsonSerializer.
