ActionFIlterAttribute

Question

User527076549 posted

Before an action is executed, information about the action must be written to a log. After results
are returned, information about the results also must be written to the log.
You need to log the actions and results

what shoul be the answers for target1 and target2

Before action executed =         OnActionExecuting(ActionExecutingContext filterContext)

after result returned = once action executed you get the result ,so "OnActionExecuted(ActionExecutedContext filterContext)"

Can anyone tell me if i am right or wrong ?

you can get result in  OnResultExecuting in as well ..

 public class LogActionFilter : ActionFilterAttribute

    {
        public override void TARGET1
        {
            Log("LOGACTION", filterContext.RouteData);
        }

        public override void TARGET2
        {
          
            Log("LOGRESULT", filterContext.RouteData);
        }

      }

I really appreciate your help.Thank you

Hi amithashenoy,

Yes, you are right. The base ActionFilterAttribute class has the following methods that you can override:

• OnActionExecuting – This method is called before a controller action is executed.
• OnActionExecuted – This method is called after a controller action is executed.
• OnResultExecuting – This method is called before a controller action result is executed.
• OnResultExecuted – This method is called after a controller action result is executed.

For more, you can refer to
