title: C# - Request to data URI scheme
body: <p>I am using the <code>Google Charts API</code> in my <code>.NET</code> application and I would like to programmatically save the chart rendered as an image by passing the chat URI in an <code>AJAX</code> request to the server.</p>
  
  <p>The problem is that the URI of the chart is a <code>data</code> URI scheme so it looks like this: <code>data:image/png;base64,abcdef...</code></p>
  
  <p>I tried to request this URI with the <code>HttpClient</code>, <code>WebClient</code> and <code>WebRequest</code> classes but all of these launched an exception saying that the URI prefix is not recognized or not handled...</p>
  
  <p>Does anyone knows wich library I can use to request this kind of URI?</p>
