Decode JSON Object in C# without prior knowledge of type [duplicate]

Question

I have some working code:

String objstr = "{\"m_children\":[{\"m_children\":null,\"m_name\":\"child0\"},{\"m_children\":null,\"m_name\":\"child1\"}],\"m_name\":\"Root\"}";
byte[] byteArr = Encoding.ASCII.GetBytes(objstr);
MemoryStream ms = new MemoryStream(byteArr);
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(Node));

Node obj = (Node)ser.ReadObject(ms);

What bugs me is that I have to know the type of the object contained in the string before I decode it. I wanted to send an object encoded in JSON over a TCP pipe, and not have to send extra information about what type the object is.

With .NET 4.0 you can use dynamic objects. Why not try out this solution from another question: Deserialize JSON into C# dynamic object?
