I am creating a custom action filter for asp.net MVC.

In the OnActionExecuting() method.

public override void OnActionExecuting(ActionExecutingContext filterContext)
{
    string userName =  ?????// how can I get this?
}

I need to find out the current users name (I am using forms authentication)

In the controller I can simply just do User.Identity.Name

Is there a way to get the users name in the ActionFilter?

string userName = filterContext.HttpContext.User.Identity.Name;

And if you wanted to check if there is an authenticated user first:

string userName = null;
if (filterContext.HttpContext.User.Identity.IsAuthenticated)
{
    userName = filterContext.HttpContext.User.Identity.Name;
}
