What are authorization filters in C#?

Authorization filters in C# are used to enforce security policies on actions in ASP.NET applications, determining if a user has permission to execute a specific action.

How do I implement an authorization filter in my ASP.NET application?

You can implement an authorization filter by creating a class that inherits from the IAuthorizationFilter interface and overriding the OnAuthorization method.

Can you give me an example of a custom authorization filter?

Sure! Here's a simple example:

public class CustomAuthorizationFilter : IAuthorizationFilter
{
    public void OnAuthorization(AuthorizationFilterContext context)
    {
        // Your authorization logic here
        if (!context.HttpContext.User.Identity.IsAuthenticated)
        {
            context.Result = new UnauthorizedResult();
        }
    }
}
