How do you clear cookies using asp.net mvc 3 and c#?

Question

Ok, so I really think I am doing this right, but the cookies aren\'t being cleared.

 Session.Clear();
 HttpCookie c = Request.Cookies[\"MyCookie\"];
 if (c !

I did this and it worked for clearing (not deleting) a session cookie:

HttpContext.Response.Cookies.Set(new HttpCookie("cookie_name"){Value = string.Empty});

Based on Metro's response I created this extension method to make the code reusable in any controller.

/// 

/// Deletes a cookie with specified name
/// 
/// extends the controller
/// cookie name
public static void DeleteCookie(this Controller controller, string cookieName)
{
    if (controller.HttpContext.Request.Cookies[cookieName] == null)
            return; //cookie doesn't exist

    var c = new HttpCookie(cookieName)
                {
                    Expires = DateTime.Now.AddDays(-1)
                };
    controller.HttpContext.Response.Cookies.Add(c);
}
