How can I grab the last folder in the URL, before the ending .aspx page?

example: "/folder1/folder2/..../mypage.aspx

I want to parse out the last folder name right before the last /
 

This should work for any number of folders even if there is only one

 
String myUrl = Convert.ToString(Request.Url);
String directoryPath = myURL.Substring(0, myURL.LastIndexOf("/"));
//directoryPath will be all folders and parse out the filename: folder1/folder2/folder3
String lastDirectory = directoryPath.Substring(directoryPath.LastIndexOf("/") + 1);
//lastDirectory will only be the last foldername 
 

string virtualPath = "/folder1/folder2/folderN/mypage.aspx";
string directory = VirtualPathUtility.GetDirectory(virtualPath);
string[] folders = directory.Split('/', StringSplitOptions.RemoveEmptyEntires);
string lastFolder = folders.Length > 0 ? folders[folders.Length - 1] : String.Empty;
