Как говорит @Ishmael, вы можете использовать систему.UriBuilder. Вот пример:

// the URI for which you want to change the host name
var oldUri = Request.Url;

// create a new UriBuilder, which copies all fragments of the source URI
var newUriBuilder = new UriBuilder(oldUri);

// set the new host (you can set other properties too)
newUriBuilder.Host = "newhost.com";

// get a Uri instance from the UriBuilder
var newUri = newUriBuilder.Uri;
