Over, the Log course derived the ActionFilterAttribute class. It logs in advance of and after the motion technique or final result executes. It is possible to utilize the Log attribute to any controller or an action method in which you would like to log the execution from the motion system.
Prior to Outcome Execution (OnResultExecuting): This method is executed just before the motion result's executed. You should utilize this technique to change the action outcome or insert further processing just before the result is taken care of.
To stop unneeded processing, check out to apply filters only where They're genuinely needed, Otherwise then stay away from applying them.
World wide filters are configured within just Startup.cs. Attribute-dependent filters that do not demand any dependencies can merely inherit from an present attribute of the right form to the filter in issue. To create a filter without
The OnActionExecuted technique runs following the action approach and may see and manipulate the outcome with the action throughout the ActionExecutedContext.Final result assets. ActionExecutedContext.Canceled will be set to correct In the event the action execution was quick-circuited by Yet another filter.
Handle access to motion solutions, and so are the initial filters to become executed throughout the filter pipeline. They have got just a ahead of phase, compared with most filters that assist prior to and right after methods. You'll want to only produce a customized authorization filter When you are composing your very own authorization framework.
Final result filters are perfect for any logic that needs to directly encompass watch execution or formatter execution. End result filters can change or modify the motion end result that’s liable for creating the reaction.

Look at The end result Variety: The method initial checks if the motion strategy’s outcome (context.Result) is of type ViewResult. ViewResult is usually a style of action final result that renders a watch since the response to your request.
Exception filters cope with unhandled exceptions, which includes people who come about throughout controller generation and filters in asp.net mvc product binding.

You'll find different types of filters within the Asp.Net Main. Underneath are the various filter varieties and their importance in the method movement.
IOrderedFilter trumps scope when analyzing the get in which filters will operate. Filters are sorted initial by order, then scope is employed to break ties. Purchase defaults to 0 if not set.
Going logic out of your controller into characteristics is perfect for lowering code complexity and implementing constant runtime habits. Unfortunately, in case you run unit exams instantly towards your action solutions, your tests aren’t planning to provide the attribute or filter behavior applied to them. This can be by style and design, not to mention you'll be able to unit take a look at your filters unbiased of unique motion methods to make sure they operate as built.
