Calling a Method After a Controller Action in ASP.NET MVC

Question

I used to believe that the following method would be invoked after all controller methods are done at the end:

protected override void EndExecute(IAsyncResult asyncResult)

Now all override methods are called and then, controller methods are invoked. Do you know what override method is invoked after all methods?

Answer 1

You can use action filter it will be called every time any method execute. You can filter it by matching method name.

 public class LogActionFilter : ActionFilterAttribute
 {
      public override void OnActionExecuting(ActionExecutingContext filterContext)
      {
           Log("OnActionExecuting", filterContext.RouteData);       
      }

      public override void OnActionExecuted(ActionExecutedContext filterContext)
      {
           Log("OnActionExecuted", filterContext.RouteData);       
      }

      public override void OnResultExecuting(ResultExecutingContext filterContext)
      {
           Log("OnResultExecuting", filterContext.RouteData);       
      }

      public override void OnResultExecuted(ResultExecutedContext filterContext)
      {
           Log("OnResultExecuted", filterContext.RouteData);       
      }


      private void Log(string methodName, RouteData routeData)
      {
           var controllerName = routeData.Values["controller"];
           var actionName = routeData.Values["action"];
           var message = String.Format("{0} controller:{1} action:{2}", methodName, controllerName, actionName);
           Debug.WriteLine(message, "Action Filter Log");
      }

 }
