Question

How can I de-serialize a json object sent from javascript (using jquery.ajax) to a .aspx page (not a web service)?

e.g. if I have the following json object;

var json = {"name" : "michael", "surname" : "brown", "age" : "35"}

and I use

$.post('process.aspx', json)

how do I get to deserialize the json in process.aspx code behind?

also, how do I use the $.postJSON() in my case?

You can use the DataContractJsonSerializer built into .Net 3.5, or there’s a great open source Json library that we use: http://jayrock.berlios.de/

To use the DataContractJsonSerializer, your code might look something like this:

var serializer = new DataContractJsonSerializer(typeof(Person));
using (MemoryStream ms = new MemoryStream(new ASCIIEncoding().GetBytes(myString)))
{
  try
  {
    Person obj = serializer.ReadObject(ms) as Person;
  }
  catch (Exception e)
  {
    throw new InvalidOperationException("Could not deserialize Person.", e);
  }
}
