            HttpContext.Current.Response.Flush(); // Sends all currently buffered output to the client.
            HttpContext.Current.Response.SuppressContent = true;  // Gets or sets a value indicating whether to send HTTP content to the client.
            HttpContext.Current.ApplicationInstance.CompleteRequest(); 

            //HttpContext.Current.ApplicationInstance.CompleteRequest();
        }
        catch(Exception ex)

Apart from what others have said, I would recommend using Web API if you want to consider generating responses in JSON or XML format. Web APIs are very easy to program, and only take required data as input and generate only require data as output — nothing more, nothing less.

Hi
I would recommend you change your method to [WebMethod] with return type of Dynamic/Object and serialize your results to JSON.

Send your requests to that web method using AJAX.

Hi,
You can use following method to convert JSON string from Object.

C#

public class Message
{
    public string Description { get; set; }
    public int Id { get; set; }  
}
Message myReturnData = new Message() { Description = "This is test description", Id = 1 };
string json = JsonConvert.SerializeObject(myReturnData);

You must have reference of newtonsoft JSON Library Introduction[^]
