Can you tell me about the different filters used in MVC architecture?

In MVC (Model-View-Controller) architecture in C#, filters are often used to inject additional logic at different stages of HTTP request processing. The main types of filters:

• Authorization Filters — check user access rights before executing a controller action.
• Action Filters — run before and after the action method, allowing logic to be executed around request processing.
• Result Filters — run before and after the result is generated (e.g., before rendering a view).
• Exception Filters — handle exceptions that occur during request processing.

Example of a simple Action Filter in C#:

public class LogActionFilter : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext context)
    {
        Console.WriteLine("Action execution started");
    }

    public override void OnActionExecuted(ActionExecutedContext context)
    {
        Console.WriteLine("Action completed");
    }
}

Filters help centrally manage cross-cutting concerns such as logging, authorization, error handling, etc.
