What are the different types of filters in ASP.NET MVC?
In ASP.NET MVC, there are several types of filters: Authorization filters, Action filters, Result filters, and Exception filters. Each serves a different purpose in the request processing pipeline.
Can you explain what each filter type does?
Sure! Authorization filters determine if a user is authorized to access a resource. Action filters run before and after an action method executes, allowing you to add logic around the action. Result filters run after the action method but before the result is executed, and Exception filters handle errors that occur during the execution of an action.
How do I implement a custom action filter?
To create a custom action filter, you can inherit from the ActionFilterAttribute class and override methods like OnActionExecuting or OnActionExecuted to add your custom logic.
