The results of the Index motion is revealed down below - the reaction headers are displayed on the bottom suitable.
The OnResultExecuting method runs before the action result's executed, so it may manipulate the action consequence by way of ResultExecutingContext.Outcome. An OnResultExecuting process can shorter-circuit execution of your motion result and subsequent end result filters by setting ResultExecutingContext.
As demonstrated from the under code, the ActionExecutionDelegate parameter is accountable for the execution call of another filter motion. Also, we can execute the motion strategy code before the filter executions.
If both asynchronous and synchronous interfaces are executed in one course, only the async method known as. When applying abstract lessons like ActionFilterAttribute, override just the synchronous methods or maybe the asynchronous strategies for every filter form.
Begin a Timer: It initializes and starts the Stopwatch to measure the length on the action’s execution. This is vital for logging the action’s execution time.
You may quick-circuit the filter pipeline at any stage by location the Result property over the context parameter supplied to your filter approach. For instance, the subsequent ShortCircuitingResourceFilter will avoid another filters from jogging later within the pipeline, like any motion filters.
As you can see, now the LogFilter class is derived from the ActionFilterAttribute abstract course and we also override all four methods. Now, it logs prior to and following the motion technique or consequence executes.
