How to get the root Url

Question

The code below is a dreadful hack.

Uri linkUri = HttpContext.Current.Request.Url; string link = linkUri.ToString().Substring(0, linkUri.ToString().IndexOf("Users/Create"));

Instead of editing the string, how do I get the correct route Url in the first place? For example I want to get http://localhost:9999/ instead of http://localhost:9999/Users/Create

Answer 1

You could use the Content method of UrlHelper:

string root = urlHelper.Content("~/");

Answer 2

It's pretty ugly, but how about:

Uri uri = new Uri("http://localhost:9999/Users/Create");
string link = string.Format("{0}://{1}:{2}", uri.Scheme, uri.Host, uri.Port);

Edit: or even better:

uri.GetLeftPart(UriPartial.Authority)
