Getting the ASPX File Name

I only used this once, and quickly changed my approach so I didn't need to rely on it, but here's how you can get the name of the ASPX file you're viewing.

string pageName = this.Page.GetType().Name.Replace("_", ".");

Of course, there's also

Request.ServerVariables["SCRIPT_NAME"]

and

HttpContext.Current.Request.Path

and

System.IO.Path.GetFileNameWithoutExtension(Request.FilePath)
