A very short note: I was trying to find an analogue to Java’s File.toURI().toURL() method in .NET, looking through System.IO et al, and not finding it on the lazyweb. To my surprise, all you need use is UriBuilder: new UriBuilder(@”c:\path\to\file.txt”).ToString(); This will output “file://c:/path/to/file.txt“. Simple, but far too much time wasted finding it…
