{
public Form1()
{
InitializeComponent();
CheckForIllegalCrossThreadCalls = false;
}

private void Form1_Load(object sender, EventArgs e)
{
//保存所有连接
var allSockets = new List();
//初始化服务端
var server = new WebSocketServer("ws://0.0.0.0:8181");
//开始监听
server.Start(socket =>
{
//有客户端连接触发
socket.OnOpen = () =>
{
textBox3.Text += socket.ConnectionInfo.ClientIpAddress + " 连接 \r\n";
allSockets.Add(socket);
};
//有客户端断开触发
socket.OnClose = () =>
{
textBox3.Text += socket.ConnectionInfo.ClientIpAddress + " 断开连接 \r\n";
allSockets.Remove(socket);
};
//接收客户端发送的消息
socket.OnMessage = message =>
{
textBox3.Text += socket.ConnectionInfo.ClientIpAddress + " 发送了消息：" + message + "\r\n";
//发送接收到的消息给所有客户端
allSockets.ToList().ForEach(s => s.Send(message));
};
