Asp.net Web API - Add attribute to each controller

Question

I have a project with an ASP.net Web API. Now i have created a custom attribute. I can set that attribute for each controller, but how can i set it on each controller at once? Is there something for in the startup class?

Answer 1

Go to the App_Start > WebApiConfig.cs file.

In the Register method add this line:

config.Filters.Add(new MyCustomAttribute());

Answer 2

1. You can use a base controller and use it as a base class on every of your other controllers.

    [YourCustomAttribute]
    public class BaseController : ApiController 
    {
    }

    public class HomeController : BaseController 
    {
    }

2. Another solution is to use Conditional Filters in ASP.NET MVC 3

Using this solution you can add the attribute without a base class.
