What are some advanced examples of attributes in ASP.NET MVC?

In ASP.NET MVC, advanced attributes can include custom validation attributes, action filters, and authorization attributes. Would you like to see examples of each?

Yes, please provide an example of a custom validation attribute.

Sure! A custom validation attribute can be created by inheriting from the ValidationAttribute class. For instance, you can create an attribute that checks if a string is a valid email format.

How about an example of an action filter?

An action filter can be created by implementing the IActionFilter interface. For example, you can create a logging filter that logs the execution time of actions.

Can you explain how authorization attributes work?

Authorization attributes, like Authorize, restrict access to controllers or actions based on user roles or authentication status. You can customize them to fit your security needs.
