title: How can I Upload File (large size) using FileStream in WebService in IIS(Internt Information Services)
body: <p>I am using C# to create a service for file uploading.
  I created three methods:
  <li><code>upload_start(string filename)</code></li>
  <li><code>upload_continue(string filename, byte[] buffer)</code></li>
  <li><code>upload_end(string filename)</code></li></p>
  
  <p>It works, but I don't want to handle 3 functions from the client program. How can I open a FileStream from the client program, and let the server side finish the file upload?</p>
