Binary data from AcceptTcpClient

[joe_pool_is]

In a background worker that will be running on our Server, I am listening for data in the form of a System.Net.Mail.MailMessage object (including attachments) to come from a client on our LAN. (The client PCs and operators on our manufacturing floor do not have an email program).

This is a work in progress, so the Client Side hasnt been written yet. The plan is to save the MailMessage object to a MemoryStream, and send the MemoryStream over the network using TCP.

My current obstical comes from finding a way to convert the received MemoryStream back into a MailMessage on the Server (the receiving end) so that the Server can send the message.

How do I convert a MemoryStream of data into a MailMessage object? I tried the code below, but the compile time error is "Cannot convert type byte[] to System.Net.Mail.MailMessage".

Server Side:

try {
  SvrForm.Server.Start();
  TcpClient client = SvrForm.Server.AcceptTcpClient(); // waits for data
  if (worker.CancellationPending == true) return;
  NetworkStream stream = client.GetStream();
  try {
    byte[] buf = new byte[client.ReceiveBufferSize];
    using (MemoryStream ms = new MemoryStream(buf)) {
      int len;
      do {
        len = stream.Read(buf, 0, client.ReceiveBufferSize);
        ms.Write(buf, 0, len);
      } while (len == client.ReceiveBufferSize);
      byte[] byteFile = ms.GetBuffer();
      try {
        MailMessage email = (MailMessage)byteFile; <= ERROR HERE!!!
        if (email.From.Address != string.Empty) {
          SmtpClient client = new SmtpClient("172.16.8.200");
          client.Send(email);
        }
      } catch (Exception er1) {
        Console.WriteLine(er1.Message);
      }
      ms.Close();
    }
  } finally {
    stream.Close();
    client.Close();
    SvrForm.Server.Stop();
  }
} catch (SocketException) { // See MSDN:
  // Windows Sockets V2 API Error Code Documentation
  // for detailed description of error code
  e.Cancel = true;
} catch (ThreadAbortException err) { // If I have to call Abort on this thread
  eMsg = "Worker Thread Abort Exception:\r\n" + err.Message;
  e.Cancel = true;
} catch (Exception err) {
  eMsg = "General Error:\r\n" + err.Message;
  e.Cancel = true;
} finally {
  SvrForm.Server.Stop();
}

Any helpful tips on writing the Client Side portion are appreciated as well.
