How to handle JSON in C#?

Question

Is there an easy/elegant parser for dealing with JSON in C#? How about actually serializing/deserializing into C# objects?

Answer 1

See

Basically you can use the 'data contract' model (that's often used for WCF XML serialization) for JSON as well. It's pretty quick and easy to use standalone for little tasks, I have found.

Answer 2

JSON.Net is a pretty good library

Answer 3

There's the DataContractJsonSerializer class.

Deserialize:

DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(MyObject));
Stream s = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(json_string));
MyObject obj = ser.ReadObject(s) as MyObject;

Serialize:

DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(MyObject));
Stream s = new MemoryStream();
MyObject obj = new MyObject { .. set properties .. };
ser.WriteObject(s, obj);
s.Seek( SeekOrigin.Begin );
var reader = new StreamReader(s);
string json_string = reader.ReadToEnd();

Answer 4

DataContractJsonSerializer for serializing to/from objects.

In Silverlight 3, there's System.Json (http://msdn.microsoft.com/en-us/library/system.json%28VS.95%29.aspx), very handy.
