How do I hook invoking controller action in MVC?

In my MVC3 application I have lots of controllers and actions. Sometimes an exception is raised while executing an action. I want to be able to log that and let the exception be handled by MVC.

Something like this pseudocode:

try {
    MvcInvokeControllerAction( controller, action, params );
} catch( Exception e ) {
    trace( "Error while invoking " + controller + "-" +
       action + " with " + params + " details: " + getDetails( e ) );
    throw;
}

What I want is to be able to catch the exception before it is first processed by MVC because sometimes MVC kicking in raises another exception and I see the latter in Application_Error() and the original exception is lots.

How do I achieve such hooking?

You can override OnException Method On your Basecontrollor.

This will be a Catch block for all exceptions in Controllor Actions. just Exetnd all your Controllors from Basecontrollor

protected override void OnException(ExceptionContext filterContext)
{
}

Example

public class BaseController : Controller
{

    protected override void OnException(ExceptionContext filterContext)
    {
        base.OnException(filterContext);
        // Handle error here
    }
}


public class TestController : BaseController
{
    public ActionResult Index()
    {
        // If any exceptions then will be caught by 
        // BaseController OnException method
    }
}
