Question

If I have a class Contact:

   public class Contact
   {
    public Contact()
    {

    }

    public int ID { get; set;}
    public string firstName { get; set;}
    public string lastName { get; set;}

    }

in my code I instantiate 5 different Contact objects and their specific properties and then put them into a List<Contact>.

My questions:

• How can I convert the List<Contact> to JSON?
• How can I read the JSON back to a List<Contact>?
• How can I read from JSON the contact with ID 123 and instantiate a Contact object out of it so I have all the properties?

Much appreciated your help!
Thanks!

P.S. The JSON will look something like this ?:

{
    contacts:{
        contact:[
            {
                id:123,
                firstname:'jhon',
                lastname:'smith'
            },
            {
                id:1234,
                firstname:'robert',
                lastname:'smith'
            }
        ]
    }
}

A quick search of the web reveals suggestions for the JavaScriptSerializer

System.Web.Script.Serialization.JavaScriptSerializer oSerializer = 
new System.Web.Script.Serialization.JavaScriptSerializer();
string sJSON = oSerializer.Serialize(YOUR CLASS HERE);

I suggest you give it a try.
