Here is an example using the Uri static class:

var url = "http://www.somewhere.net/Thingy%20World.html";

var decoded = Uri.UnescapeDataString(url);
//decoded is currently 'http://www.somewhere.net/Thingy World.html'

var encoded = Uri.EscapeUriString(decoded);//back to encoded
//encoded is currently 'http://www.somewhere.net/Thingy%20World.html'
