SuperWebSocket实现服务端和WebSocket4Net实现客户端具体实现如下：

SuperWebSocket实现服务端

注：本作者是基于vs2019 enterprise版本，所有项目均为.Net Framwork4.7版本(因为WebSocket需求是.Net Framwork4.0以上版本）

1、新建控制台项目ConsoleAppWebsocketServer，作为服务端，选择项目右键管理Nuget程序包，搜索 SuperWebSocket ，选择SuperWebSocketNETServer，点击右侧 安装，

等待安装完成，安装完成以后，项目会多出很多引用库，如下

项目的Program.cs内容如下：

using SuperWebSocket;  
using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Threading.Tasks;  
using System.Web;

namespace ConsoleAppWebsocketServer  
\{  
class Program  
\{  
static void Main(string\[\] args)  
\{  
Console.WriteLine("服务端");  
WebSocketServer webSocketServer = new WebSocketServer();  
webSocketServer.NewSessionConnected += WebSocketServer\_NewSessionConnected;  
webSocketServer.NewMessageReceived += WebSocketServer\_NewMessageReceived;  
webSocketServer.SessionClosed += WebSocketServer\_SessionClosed;  
if (!webSocketServer.Setup("127.0.0.1", 1234))  
\{  
Console.WriteLine("设置服务监听失败！");  
\}  
if (!webSocketServer.Start())  
\{  
Console.WriteLine("启动服务监听失败！");  
\}  
Console.WriteLine("启动服务监听成功！");  
Console.WriteLine("按任意键结束。。。");  
Console.ReadKey();  
webSocketServer.Dispose();  
\}

private static void WebSocketServer\_NewSessionConnected(WebSocketSession session)  
\{  
string msg = $"\{DateTime.Now.ToString("HH:mm:ss")\} 客户端：\{GetwebSocketSessionName(session)\} 加入";  
Console.WriteLine($"\{msg\}");  
SendToAll(session, msg);  
\}

private static void WebSocketServer\_NewMessageReceived(WebSocketSession session, string value)  
\{  
string msg = $"\{DateTime.Now.ToString("HH:mm:ss")\} 服务端收到客户端：\{GetwebSocketSessionName(session)\}发送数据：\{value\}";  
Console.WriteLine($"\{msg\}");  
SendToAll(session, value);  
\}

private static void WebSocketServer\_SessionClosed(WebSocketSession session, SuperSocket.SocketBase.CloseReason value)  
\{  
string msg = $"\{DateTime.Now.ToString("HH:mm:ss")\} 客户端：\{GetwebSocketSessionName(session)\}关闭，原因：\{value\}";  
Console.WriteLine($"\{msg\}");  
SendToAll(session, msg);  
\}

/// <summary>  
/// 获取webSocketSession的名称  
/// </summary>  
/// <param name="webSocketSession"></param>  
public static string GetwebSocketSessionName(WebSocketSession webSocketSession)  
\{  
return HttpUtility.UrlDecode(webSocketSession.SessionID);  
\}

/// <summary>  
/// 广播，同步推送消息给所有的客户端  
/// </summary>  
/// <param name="webSocketSession"></param>  
/// <param name="msg"></param>  
public static void SendToAll(WebSocketSession webSocketSession, string msg)  
\{  
foreach (var item in webSocketSession.AppServer.GetAllSessions())  
\{  
item.Send(msg);  
\}  
\}  
\}  
\}

WebSocket4Net实现客户端

2、新建控制台项目ConsoleAppWebsocketClient，作为客户端，选择项目右键管理Nuget程序包，为了测试SuperWebSocket作为服务端的功能，本文客户端使用了WebSocket4Net，同样也可以使用 SuperWebSocket ，本项目选择WebSocket4Net，点击右侧 安装，等待安装完成，安装完成之后，同样项目下会多一些引用库，如下：

![694927-20190719004039860-1210947778.png][]

项目的Program.cs内容如下：

using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Threading.Tasks;  
using WebSocket4Net;  
using System.Threading;

namespace ConsoleAppWebsocketClient  
\{  
class Program  
\{  
public static WebSocket webSocket4Net = null;  
static void Main(string\[\] args)  
\{  
Console.WriteLine("客户端");  
webSocket4Net = new WebSocket("ws://127.0.0.1:1234");  
webSocket4Net.Opened += WebSocket4Net\_Opened;  
webSocket4Net.MessageReceived += WebSocket4Net\_MessageReceived;  
webSocket4Net.Open();  
Console.WriteLine("客户端连接成功！");  
Thread thread = new Thread(ClientSendMsgToServer);  
thread.IsBackground = true;  
thread.Start();

Console.WriteLine("按任意键结束。。。");  
Console.ReadKey();  
webSocket4Net.Dispose();  
\}

public static void ClientSendMsgToServer()  
\{  
int i = 88;  
while (true)  
\{  
//Console.WriteLine($"客户端发送数据\{i++\}");  
webSocket4Net.Send($"\{i++\}");  
Thread.Sleep(TimeSpan.FromSeconds(5));  
\}  
\}

private static void WebSocket4Net\_MessageReceived(object sender, MessageReceivedEventArgs e)  
\{  
Console.WriteLine($"服务端回复数据:\{e.Message\}！");  
\}

private static void WebSocket4Net\_Opened(object sender, EventArgs e)  
\{  
webSocket4Net.Send($"客户端准备发送数据！");  
\}  
\}  
\}

3、测试

为了更好的看到测试效果，又多使用了js客户端来测试，添加html文件，命名websockettest.html，内容如下：

<!DOCTYPE HTML>  
<html>  
<head>  
<meta http-equiv="content-type" content="text/html" />  
<meta name="author" content="https://www.baidu.com" />  
<title>websocket test</title>  
<script>  
var socket;  
function Connect()\{  
try\{  
socket=new WebSocket('ws://127.0.0.1:1234');  
\}catch(e)\{  
alert('error');  
return;  
\}  
socket.onopen = sOpen;  
socket.onerror = sError;  
socket.onmessage= sMessage;  
socket.onclose= sClose;  
\}  
function sOpen()\{  
alert('connect success!');  
\}  
function sError(e)\{  
alert("error " + e);  
\}  
function sMessage(msg)\{  
document.getElementById("msgrecv").value = msg.data;

\}  
function sClose(e)\{  
alert("connect closed:" + e.code);  
\}  
function Send()\{  
socket.send(document.getElementById("msg").value);  
\}  
function Close()\{  
socket.close();  
\}  
</script>  
</head>  
<body>  
<input id="msg" type="text" size = "200" >  
<input id="msgrecv" type="text" size = "200">  
<button id="connect" οnclick="Connect();">Connect</button>  
<button id="send" οnclick="Send();">Send</button>  
<button id="close" οnclick="Close();">Close</button>  
</body>  
</html>

4、运行结果

到此位置所有的准备工作都完成了，一个服务端ConsoleAppWebsocketServer，两个客户端(ConsoleAppWebsocketClient，websockettest.html)，那么接下来运行项目

解决方案 右键，属性，设置启动项目如下：

启动服务端ConsoleAppWebsocketServer，客户端ConsoleAppWebsocketClient之后，再去手动点击websockettest.html，

运行效果：
