I'm writing a method which, let's say, given 1 and hello should return http://something.com/?something=1&hello=en.
I could hack this together pretty easily, but what abstraction functionality does ASP.NET 3.5 provide for building URIs? I'd like something like:
URI uri = new URI("~/Hello.aspx"); // E.g. ResolveUrl is used here
uri.QueryString.Set("something", "1");
uri.QueryString.Set("hello", "en");
return uri.ToString(); // /Hello.aspx?something=1&hello=en
I found the Uri class which sounds highly relevant, but I can't find anything which does the above really. Any ideas?
(For what it's worth, the order of the parameters doesn't matter to me.)

Based on this answer to a similar question you could easily do something like:
UriBuilder ub = new UriBuilder();
// You might want to take more care here, and set the host, scheme and port too
ub.Path = ResolveUrl("~/hello.aspx"); // Assumes we're on a page or control.
// Using var gets around internal nature of HttpValueCollection
var coll = HttpUtility.ParseQueryString(string.Empty);
coll["something"] = "1";
coll["hello"] = "en";
ub.Query = coll.ToString();
return ub.ToString();
// This returned the following on the VS development server:
// http://localhost/Hello.aspx?something=1&hello=en
This will also urlencode the collection, so:
coll["Something"] = "1";
coll["hello"] = "en&that";
Will output:
Something=1&hello=en%26that
