File path passed to File.ReadAllBytes method are overridden by prepending executing path

Question

File path passed to File.ReadAllBytes methodsare overridden by prepending executing path

This is console application running as a service using TopShelf in debug.

var bytes = File.ReadAllBytes(@"‪‪d:\ubuntu-20.04.2.0-desktop-amd64.iso.torrent");

System.IO.IOException: 'The filename, directory name, or volume label syntax is incorrect. : 'C:\FR\src\Service\bin\Debug\net5.0\‪D:\ubuntu-20.04.2.0-desktop-amd64.iso.torrent

For debug purpose I added line - refer snip for it's value

var fullpath = Path.GetFullPath(command.Path);

It works for a simple .net5 console app with Topshelf. So I suspect Akka.net causing this.

Some non standard characters (not visible) are encoded before you "d:" in your string and that's why you have that behavior. If you rewrite your path manually (with the quotes) it will work.

In this example "filePathA" is copy-paste of your path and "filePathB" is the one I rewrote.

filePathA = 51 bytes

filePathB = 45 bytes
