JSON stands for Javascript Object Notation and this is the new lightweight (then XML) standart for transferring data from one point to another over the network. Here you can find a sample web page codebehind to see usage in C#.
namespace Prototype
{
public partial class Json : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//create instance of the object
SampleObject sampleObject = new SampleObject();
//Json Serialize
string json = Functions.ToJson<SampleObject>(sampleObject);
Response.Write(string.Format("Json result: {0}<br/>",Server.HtmlEncode(json)));
SampleObject deserializedSampleObject = Functions.FromJson<SampleObject>(json);//Json Deserialize
Response.Write(string.Format("Object Result: {0}<br/>", deserializedSampleObject.ToString()));
}
}
[Serializable]
public class SampleObject
{
public int Id { get; set; }
public string Name { get; set; }
public string Surname { get; set; }
public string EMail { get; set; }
public SampleObject()
{
this.Id = 2345;
this.Name = "Ozan K.";
this.Surname = "BAYRAM";
this.EMail = "xyz@abc.com";
}
public override string ToString()
{
return string.Format("{0} {1}", Name, Surname);
}
}
}

Happy codings…
