title: Upload files with HTTPWebrequest (multipart/form-data)
body: <p>Is there any class, library or some piece of code which will help me to upload files with <strong>HTTPWebrequest</strong>? </p>
  
  <p><strong>Edit 2:</strong></p>
  
  <p>I do not want to upload to a WebDAV folder or something like that. I want to simulate a browser, so just like you upload your avatar to a forum or upload a file via form in a web application. Upload to a form which uses a multipart/form-data. </p>
  
  <p><strong>Edit:</strong></p>
  
  <p>WebClient is not cover my requirements, so I'm looking for a solution with <strong>HTTPWebrequest</strong>.</p>
