title: Uri - append path
body: <p>Is there an out of the box way to append a path to an existing Uri in C#?</p>
  <p>What I have currently is something like this. To be clear, I'd like to avoid using <code>uriBuilder.Path +=</code> because that way I'd have to specify path slashes myself.</p>
  <pre class="lang-cs prettyprint-override"><code>string current = &quot;https://www.test.com/api/test/something?something=123&quot;;
  string stuff = &quot;getsomething&quot;;
  </code></pre>
  <p>My Preferred output would be <code>https://www.test.com/api/test/something/getsomething?something=123</code>. Of course, I could manually try to do it, but am I able to append the &quot;getsomething&quot; onto the path without losing the current one?</p>
