Return List to ajax mvc3

I am working on MVC3 and following is my controller

  public List<int> ddlTransType_Change(int DocID)
        {

            return UserDocumentServive.getSelectedUsers(DocID);

        }

My Ajax

  $.ajax({
                type: 'GET',
                url: "/MIS.MVC/" + "DocumentApproval/ddlTransType_Change",
                data: {
                    'DocID': $("#ddlTransType").val().trim()
                },
                success: function (result) {
                    alert(result.value)
},
error: function (e) {
                    alert("Error:Unable to load data from server");
                }
            });

Controller returns a list of int values i.e {1,74,23,1} and I want to show them in alert. any idea how to do it .?

If you are using MVC3, its better to return json data back to your ajax success call

public ActionResult ddlTransType_Change(int DocID)
    {

         List<int> list = UserDocumentServive.getSelectedUsers(DocID);;
        return Json(new
        {
            list = list
        },JsonRequestBehavior.AllowGet);

    }

Then your ajax call changes to

 $.ajax({
                type: 'GET',
                url: "/MIS.MVC/" + "DocumentApproval/ddlTransType_Change",
                data: {'DocID': $("#ddlTransType").val().trim()},
                dataType: 'json',
                success: function (result) {
                                           var list=result.list;
              $.each( list, function( index, value )
                                         {
                                            alert(value);
                                           });
                                             },
error: function (e) {
                    alert("Error:Unable to load data from server");
                }
        });
