C# WebSocket草稿76握手混淆
我想我大概是这里第一百万个有问题的人了;我真的希望有人能帮我 无论如何;我有一台C#服务器,我正试图让它与WebSocket一起正常工作,不幸的是,我无法让这该死的东西建立连接!扯掉我的头发也没用C# WebSocket草稿76握手混淆,c#,html,websocket,C#,Html,Websocket,我想我大概是这里第一百万个有问题的人了;我真的希望有人能帮我 无论如何;我有一台C#服务器,我正试图让它与WebSocket一起正常工作,不幸的是,我无法让这该死的东西建立连接!扯掉我的头发也没用 internal class Request { private delegate void _create_request(Request request); private Request(_create_request create_functi
