title: Image from string which is type of Application/Octet-stream
body: <p>I have a base64 string which is provided below. I guess its type is Application/Octet-stream.
  I am using code below to convert it to an image. But it gives me error "Paramter is not valid!".</p>
  
  <pre><code>string base64string = "AAAAAQEAAAEcEgABHxIAASAS ... F4WQABcFwAAQ==";
  
  using (MemoryStream ms = new MemoryStream(Convert.FromBase64String(base64string)))
  {
      pictureEdit1.Image = Image.FromStream(ms, true);
  }
  </code></pre>
  
  <p>You can get full string from here: <a href="http://orion.mn/updateapp/base64_unicode_string.rar" rel="nofollow">http://orion.mn/updateapp/base64_unicode_string.rar</a></p>
