}服务端使用代码:
ServerPipe server = null;
public MainWindow()
{
InitializeComponent();
server = new ServerPipe("test1");
server._resultCallBackEvent += (code, msg) =>
{
Console.WriteLine($"{code}-----{msg}");
if (msg.IndexOf("init")>-1)
{
server.ServerSend("How are you" + DateTime.Now.ToString("O"));
}
server.ResetPipe();
};
server.Receive();
}
客户端使用代码
ClientPipe client = new ClientPipe("test1");
client.resultClientCallBackEvent += (code, msg) =>
{
Console.WriteLine($"{code}-----{msg}");
};
System.Timers.Timer timer1 = null;
timer1 = new System.Timers.Timer();
timer1.Elapsed += delegate
{
client.Send("init" + DateTime.Now.ToString("O"));
};
timer1.Interval = 1000; // 每1秒重复检测一次
timer1.Start();
