Convert UNC path to 'file:///' URL in ASP.NET

Question

I need to convert UNC paths to file:/// URLs. For example:

\\fileserver\share\dir\some file.ext --> file://///fileserver/share/dir/some%20file.ext

Is there a built-in function for this?

That doesn't look like the right output. `file://///fileserver/share/file.txt` means a file on localhost whose name is `//fileserver/share/file.txt`. — Lucian Wischik, Jun 12 '17 at 22:25

Yes, use the Uri class in the System namespace:

Uri uri = new Uri(@"\\fileserver\share\dir\some file.ext");
string url = uri.AbsoluteUri;

This gives "file://fileserver/share/dir/some%20file.ext" and not "file://///fileserver/share/dir/some%20file.ext" which op explicitly requested. What the "correct" way of encoding UNC paths as urls is can be a lenghty discussion, see e.g. https://bugzilla.mozilla.org/show_bug.cgi?id=66194 - but nevertheless this fails at answering op's question. – poizan42 Mar 01 '16 at 21:36
