我有 ac# 客户端，我正在尝试连接到 websocket 服务器。使用 Chrome 扩展程序“Simple Web Socket Client”，我可以连接并将命令正常发送到 websocket 服务器，因此我知道服务器工作正常并且它是一个商业产品。

我正在尝试使用库 WebSocketSharp，但在尝试连接到套接字时出现此错误。只是为了让您知道没有代理服务器在运行，并且服务器位于内部网络上。

使用wireshark我跟随流并将其作为握手的一部分

  GET / HTTP/1.1
  User-Agent: websocket-sharp/1.0
  Host: 192.168.0.29:55537
  Upgrade: websocket
  Connection: Upgrade
  Sec-WebSocket-Key: o0Smz22nOFWLW/3hvyvYQQ==
  Sec-WebSocket-Extensions: permessage-deflate; server_no_context_takeover; client_no_context_takeover
  Sec-WebSocket-Version: 13

  ....HTTP/1.1 101 Switching Protocols
  Connection: Upgrade
  Upgrade: websocket
  Sec-WebSocket-Accept: guJWynqtY1ZrPq+m6bfUGE2yJvA=

任何想法？我什至尝试过 WebSocket4Net 并且连接也有问题。
