catching exception thrown By CustomAuthorizeAttribute ASP.NET MVC 4

Question

Suppose I have A CustomAuthorizeAttribute and I thew Exception in HandleUnauthorizedRequest . Is there any way to catch that exception and format the message and display it to the user. If not than how should a thing like this be implemented.

Answer 1

Do you want to do this globally? Or on a per controller basis?

If Globally, then you can create your own HandleErrorAttribute which will catch any unhandled exceptions. You can then test if the exception is HandleUnauthorizedRequest or not.

If you want to do this on a per controller basis, then you can override OnException and handle it there.
