title: C# Download webpage content with given parameters
body: <p>I have a problem. I am trying to get the content of my webpage, so I found this code:</p>
  
  <pre><code>WebClient client = new WebClient();
  string downloadString = client.DownloadString("mysite.org/page.php");
  </code></pre>
  
  <p>But I have a few <code>$_POST</code> variables in my php page, so how can I add them to the download of the page?</p>
