Absolute URL from base + relative URL in C#

Question

I have a base URL :

http://my.server.com/folder/directory/sample

And a relative one :

../../other/path

How to get the absolute URL from this ? It's pretty straighforward using string manipulation, but I would like to do this in a secure way, using the Uri class or something similar.

It's for a standard a C# app, not an ASP.NET one.

Answer 1

var baseUri = new Uri("http://my.server.com/folder/directory/sample");
var absoluteUri = new Uri(baseUri,"../../other/path");

OR

Uri uri;
if ( Uri.TryCreate("http://base/","../relative", out uri) ) doSomething(uri);
