可能是编码问题。这是我编写的可运行的C＃服务器：
class Program{ static void Main(string[] args) { var listener = new TcpListener(IPAddress.Loopback, 8181); listener.Start(); using (var client = listener.AcceptTcpClient()) using (var stream = client.GetStream()) using (var reader = new StreamReader(stream)) using (var writer = new StreamWriter(stream)) { writer.WriteLine("HTTP/1.1 101 Web Socket Protocol Handshake"); writer.WriteLine("Upgrade: WebSocket"); writer.WriteLine("Connection: Upgrade"); writer.WriteLine("WebSocket-Origin: http://localhost:8080"); writer.WriteLine("WebSocket-Location: ws://localhost:8181/websession"); writer.WriteLine(""); } listener.Stop(); }}以及相应的客户端托管在
localhost:8080：

May send data now...'); }; socket.onclose = function() { alert('connection closed'); }; </script> </head> <body> </body></html>本示例仅建立握手。建立握手后，您将需要调整服务器以继续接受数据。
