How to add global ASP.Net Web Api Filters

asp.net-mvc-4asp.net-web-api

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?

Best Solution

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);
}
