How to remove the port number from a url string

Question

I have the following code snippet:

string tmp = String.Format(\"

        

Answer 1

You can also use the properties of URIBuilder for this, it has properties for outputting an url the way you want

Answer 2

UriBuilder u1 = new UriBuilder( "http://www.example.com:80/dir/?query=test" );
u1.Port = -1;
string clean = u1.Uri.ToString();

Setting the Port property to -1 on UriBuilder will remove any explicit port and implicitly use the default port value for the protocol scheme.
