title: How to post data using HttpClient?
body: <p>I have got <a href="http://www.nuget.org/packages/Microsoft.Net.Http" rel="noreferrer">this</a> HttpClient from Nuget.</p>
  <p>When I want to get data I do it this way:</p>
  <pre><code>var response = await httpClient.GetAsync(url);
  var data = await response.Content.ReadAsStringAsync();
  </code></pre>
  <p>But the problem is that I don't know how to post data?
  I have to send a post request and send these values inside it: <code>comment=&quot;hello world&quot;</code> and <code>questionId = 1</code>. these can be a class's properties, I don't know.</p>
  <p><strong>Update</strong> I don't know how to add those values to <code>HttpContent</code> as post method needs it. <code>httClient.Post(string, HttpContent);</code></p>
