I need to find the best way to check if data was sent & received successfully without implementing a return message by the receiving side. My thought has been to write the message to the socket, see if I can still write to the socket, and if I can, I can know that the message was sent successfully without transmission interruption. If I cant still write, then I know that the connection has closed prematurely. Also, I will check for errors, but the IsError() function has not detected dropped connections for me.
This would look something like:

socket.Write(message);
if(socket.PeekWrite()){
   socket.Close();
   return true; //
}else{
   socket.Close();
   return false;
}

Is this correct? Wouldnt the Write() method cause a Socket Error to be set if it could not write the whole message?
Am I interpreting PeekWrite correctly? Does it check to see if the socket is writable or if there is content waiting to be written?
Also, what does PeekAbort() do?
