How to return values from Webmethod to the client in JSON format?

There are two static int values that i want to return.

Do I need to create new object with those 2 properties and return it?

The GetStatus() method is called frequently and i don't like the idea of creating a special object each time just for json formatting...

[WebMethod]

public static int GetStatus()

{

    int statusProcess,statusProcessTotal;



    Status.Lock.EnterReadLock();

    statusProcess=Status.Process; //Static field

    statusProcessTotal=Status.ProcessTotal; //Static field        

    Status.Lock.ExitReadLock();



    return ...

}

On client side I catch the return value in :

function OnSucceeded(result, userContext, methodName)   

(PageMethods.GetStatus(OnSucceeded, OnFailed);)

I would just go with an object. It fits with what you need to do. If you have two return values you have to put them together in a structured way.

  public class StatusResult

        {

            public int StatusProcess { get; set; }

            public int StatusProcessTotal { get; set; }

        }



  [WebMethod]

        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]

        public StatusResult GetStatus()

        {

            int statusProcess,statusProcessTotal;



            //Status.Lock.EnterReadLock();

            statusProcess = 5;

            statusProcessTotal = 1; //Static field        





            var result = new StatusResult();

            result.StatusProcess = statusProcess;

            result.StatusProcessTotal = statusProcessTotal;



            return result;

        }
