NameValueCollection to URL Query?

Question

I know i can do this

var nv = HttpUtility.ParseQueryString(req.RawUrl);

But is there a way to convert this back to a url?

I always use UriBuilder to convert an url with a querystring back to a valid and properly encoded url.

var url = "http://my-link.com?foo=bar";

var uriBuilder = new UriBuilder(url);
var query = HttpUtility.ParseQueryString(uriBuilder.Query);
query.Add("yep", "foo&bar");

uriBuilder.Query = query.ToString();
var result = uriBuilder.ToString();

// http://my-link.com:80/?foo=bar&yep=foo%26bar
