Pass Stringbuilder message from Json [MVC-Controller]and render it in view

Question

I am trying to pass a StringBuilder message as an extra data back to ajax call but I am failing to manipulate it in client side. Below is the way I append message to StringBuilder and pass it back.

StringBuilder retMessage=new StringBuilder();
retMessage.Clear().AppendLine("Successfully added the user!"); 
//Clear will done only on Success otherwise will append the different errorMessage using AppendLine
return Json(new { result = valid, message = retMessage });

On the ajax Success I tried retrieving it as below but with no success.

 success: function (data) {
              if (data.result) {
                    ResetForm('#frmChangePwd');
                    console.log(data.message);
              },
 }

Below are images showing how it is passed from server side and how it is obtained in client side!!

Can anyone tell me how to retrieve message in client side and display it in view?

Did you try calling the to String method on the stringbuilder when you constructed the object literal. — Robert Moskal

You need to call .ToString() on the StringBuilder - return Json(new { result = valid, message = retMessage.ToString() }); — user3559349

And just by way of explanation, without .ToString() your passing the instance of the StringBuilder so the Json method serializes the instance from its public properties, but the actual text output is internal so its not sent - only the 3 public properties that you see in the browser — user3559349

Call the toString method on the StringBuilder even you create the anonymous object on the return from the server.
