  Why to call base.OnException

  Jan 08, 2013 06:55 PM|LINK

  Hi,

  I found the following sample code for custom exception filter:

  public class CustomExceptionFilter: ExceptionFilterAttribute
  {
  public override void OnException(HttpActionExecutedContext context)
  {
  if(context.Response == null)
  {
  context.Response = new HttpResponseMessage();
  }
  context.Response.StatusCode = HttpStatusCode.NotImplemented;
  context.Response.Content = new StringContent("Custom Message");
  base.OnException(context);
  }
  }

  In the above code why base.OnException is there, what is the purpose of this and is it required?

  Thanks
