Uri u = new Uri("http://audacity.googlecode.com/files/audacity-win-2.0.exe");
Path.GetFileName(u.AbsolutePath);

This should be the accepted answer. If you check uri.IsFile will give you false because is not a local file. – Arnel Oct 21 '18 at 04:24

How about

Path.GetFileName(string path);

In your case

Path.GetFileName(new Uri("http://audacity.googlecode.com/files/audacity-win-2.0.exe").AbsolutePath);

This might be old but with this method for the example you will get empty string on the filename since IsFile is only true when you give a file:// type URI – Alfredo Alvarez Feb 10 '15 at 21:56

E.g.

Uri uri = new Uri("http://audacity.googlecode.com/files/audacity-win-2.0.exe");
string Path.GetFileName(uri.AbsolutePath);

It is not safe to assume that a URI will always represent physical files therefore extracting file name from a URI is not always guaranteed.
