copied!<p><code>ReadLine</code> hangs because it is waiting for a newline, which your test message doesn't include.</p> <p>If you want the server to send messages continuously just put a loop round the <code>WriteFile</code> call. You don't need to connect more than once. Similarly in the client, put the loop around <code>ReadLine</code>.</p> <p>If each message consists of text terminated by a newline then that should suffice, but if you really want the pipe client to work in message mode you need to call:</p> <pre><code>pipeClient.ReadMode = PipeTransmissionMode.Message; </code></pre> <p>However, I doubt this would interact well with a <code>StreamReader</code>. Instead, you should read single messages using <code>pipeClient.Read</code>.</p> <p><strong>Update</strong></p> <p>To answer your new question:</p> <p>On the server, once the client has connected enter a loop in which:</p> <ul> <li>The server does a read from the client. This will block until the client requests a frame.</li> <li>The server sends a frame.</li> </ul> <p>On the client, once it has connected to the server enter a loop in which:</p> <ul> <li>The client sends a "please send a frame" message.</li> <li>The client does a read from the server to get the frame.</li> <li>The client displays the frame.</li> </ul> <p>I wouldn't use a message mode pipe. If the frames are fixed in size then the client knows how much data to read from the server. Otherwise, precede the frame with a uint containing its length.</p>
