UriBuilder and "../../" in uri

Question

I need to combine two urls, but it seems that UriBuilder doesn't support url's with ../../ in them. Is my only option to code this by hand? I'm trying something like this :

Uri pageUri = new Uri("http://site.com/a/b/c.html");
string redirectUrl = "../../x.html";

UriBuilder builder = new UriBuilder(pageUri);
builder.Path += redirectUrl;

Thanks for any tips on how to do this the right way.

Answer 1

This is working fine for me. You tried to call builder.Uri.OriginalString to get the full address back?

Answer 2

You could also to use:

Uri redirect = new Uri(
    new Uri("http://site.com/a/b/c.html"), "../../x.html");
