The best way is to use System.Web.Script.Serialization.JavaScriptSerializer

A simple Employee object:

public class Employee
{
    public string Name { get; set; }
    public string Age { get; set; }
    public string ID { get; set; }   
}

Adding some instances of them to a List:

Employee oEmployee1 = 
       new Employee{Name="Pini",ID="111", Age="30"};

Employee oEmployee2 = 
      new Employee { Name = "Yaniv", ID = "Cohen", Age = "31" };
Employee oEmployee3 = 
        new Employee { Name = "Yoni", ID = "Biton", Age = "20" };

List<Employee> oList = new List<Employee>() 
{ oEmployee1, oEmployee2, oEmployee3 };

System.Web.Script.Serialization.JavaScriptSerializer oSerializer = 
         new System.Web.Script.Serialization.JavaScriptSerializer();
string sJSON = oSerializer.Serialize(oList);
