How to get current page Filename using C#

There are different ways to get current page filename using c#. Here are 3 methods you can use for your advantage.

Method 1

string currentPageFileName = new FileInfo(this.Request.Url.LocalPath).Name;

Method 2

string sPath = HttpContext.Current.Request.Url.AbsolutePath;
string[] strarry = sPath.Split('/');
int lengh = strarry.Length;
string sReturnPage = strarry[lengh - 1];

Method 3

string absPath = System.Web.HttpContext.Current.Request.Url.AbsolutePath;
System.IO.FileInfo finfo = new System.IO.FileInfo(absPath);
string fileName = finfo.Name;

 

Out of these I like Method 1 and 3 as its straight forward. Use a per your advantage. Good luck.
