title: How To Call XML POST API
body: <p>I need to call an API with POST arguments, for example:</p>
  
  <ul>
  <li>URL = <a href="http://localhost/myAPI/" rel="nofollow">http://localhost/myAPI/</a> </li>
  <li>ARGS = options=blue&amp;type=car</li>
  </ul>
  
  <p>I've had a look at XDocument but not sure how to send params in the request. I'm also not sure how I would call asynchronously, and even if I should or if it's better/easier to run in another thread. </p>
  
  <p>I'd be calling this from my windows based C# application.</p>
