converting virtual path to actual web path in ASP.NET

Question

I have a virtual path (example: "~/Images/Banner.jpg") and I want to make that an absolute web path (example: "/ApplicationRoot/Images/Banner.jpg"). There is a method that will do this, I believe in a class called something like HTTPUtility or similar name. Though ever time I need this method, it takes me hours searching for it. It would be greatly appreciated if someone could post the proper method to do this so I can favorite this for easy access in the future.

Thank you very much.

System.Web.VirtualPathUtility.ToAbsolute("yourRelativePath");
