Combine complete URL and virtual URL, like a browser does

I ha开发者_如何学Pythonve a complete URL like: A: http://www.domain.com/aaa/bbb/ccc/ddd/eee.ext.

I have a relative URL like: B: ../../fff.ext

I’m looking for the easiest way in .NET C# to combine these two URLs and get: C: http://www.domain.com/aaa/bbb/fff.ext

This is like what browsers does: you’re browsing URL A, then, page’s HTML have an hyperlink as B, the resulting URL is C.

You'd probably have better luck looking up "PathCanonicalize".

Also, with my findings, one of the overloaded Uri constructors can handle this:

Uri combined = new Uri(
  new Uri("http://www.domain.com/aaa/bbb/ccc/ddd/eee.ext", UriKind.Absolute),
  "../../fff.ext"
);

Proof is in the pudding
