Uri originalUrl = new Uri("http://www.mydomain.com/blog/currentPage.aspx?id=156"); // Request.Url
string domain = originalUrl.Host; // www.mydomain.com
string domainUrl = String.Concat(originalUrl.Scheme, Uri.SchemeDelimiter, originalUrl.Host); // http://www.mydomain.com

in addition take a look at segments.

Answer 4

You have many options:

string root = this.ResolveUrl("~")

Or

Uri requestUri = Context.Request.Url;
string baseUrl = requestUri.Scheme + Uri.SchemeDelimiter + requestUri.Host + (requestUri.IsDefaultPort ? "" : ":" + requestUri.Port);

Or

string baseUrl = Request.Url.GetLeftPart(UriPartial.Authority);

If you want /blog appended to the last two, add

+ Request.ApplicationPath
