Add the below referances before starting:

using System.Web.Script.Services;
using System.Web.Script.Serialization;

Use the below code in your method, for converting any data into JSON Data format in end:

JavaScriptSerializer serializer = new JavaScriptSerializer();
return serializer.Serialize(empData);

empData is array of DataRows from DataTable.
