How to add global ASP.Net Web Api Filters?

Question

I've created a Web Api filter (using System.Web.Http.Filters.ActionFilterAttribute) but I am unable to get it to work inside of ASP.Net MVC 4. I tried adding it to the RegisterGlobalFilters() method but that didn't work.

So if one is using Web Api hosted in ASP.Net MVC how does one register filters?

Answer 1

The following code, in my Global.asax, works for me:

public static void RegisterWebApiFilters(System.Web.Http.Filters.HttpFilterCollection filters)
{
  filters.Add(new MyWebApiFilter());
}

protected void Application_Start()
{
  RegisterWebApiFilters(GlobalConfiguration.Configuration.Filters);
}
