transform relative address to absolute address

[Franz]

Is there any class for me to transform a relative address to an absolute
address?
For example, inside the page http://www.foo.com/bar/foo1.htm, there is a
hyperlink "../bar2/foo1.htm", it is transformed to
http://www.foo.com/bar2/foo1.htm

System.Uri can do this for you;

Uri basePath = new Uri(@http://www.foo.com/bar/foo1.htm);
Uri fullPath = new Uri(basePath, @"../bar2/foo1.htm");

System.Diagnostics.Debug.WriteLine(fullPath.AbsoluteUri);

Other related items are UriBuilder, and System.Xml.XmlUrlResolver
