To me, @warlock's looks like the best answer here so far, but I've always used this in the past;
string baseUrl = Request.Url.GetComponents(
UriComponents.SchemeAndServer, UriFormat.UriEscaped)
Or in a WebAPI controller;
string baseUrl = Url.Request.RequestUri.GetComponents(
UriComponents.SchemeAndServer, UriFormat.Unescaped)
which is handy so you can choose what escaping format you want. I'm not clear why there are two such different implementations, and as far as I can tell, this method and @warlock's return the exact same result in this case, but it looks like GetLeftPart()
would also work for non server Uri's like mailto
tags for instance.
