C# 如何使用GUI在端口上进行持续侦听？

- 添加到表单文本框、列表框、按钮、公开：
public System.Windows.Forms.TextBox console; public System.Windows.Forms.ListBox incommingMessages; private System.Windows.Forms.Button sendSampleDataButton;
入口点：
private static Form1 form;
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
form = new Form1();
form.Load += OnFormLoad;
Application.Run(form);
}
private static void OnFormLoad(object sender, EventArgs e)
{
CreateServer();
}
private static void CreateServer()
{
var tcp = new TcpListener(IPAddress.Any, 25565);
tcp.Start();
var listeningThread = new Thread(() =>
{
while (true)
{
var tcpClient = tcp.AcceptTcpClient();
ThreadPool.QueueUserWorkItem(param =>

NetworkStream stream = tcpClient.GetStream();
string incomming;
byte[] bytes = new byte[1024];

form.console.Invoke(

服务器：

static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
form = new Form1();
form.Load += OnFormLoad;
Application.Run(form);
}
private static void OnFormLoad(object sender, EventArgs e)
{
CreateServer();
}
private static void CreateServer()
{
var tcp = new TcpListener(IPAddress.Any, 25565);
tcp.Start();
var listeningThread = new Thread(() =>

while (true)
{
var tcpClient = tcp.AcceptTcpClient();
ThreadPool.QueueUserWorkItem(param =>
{
NetworkStream stream = tcpClient.GetStream();
string incomming;
byte[] bytes = new byte[1024];

tcpClient.Close();
}, null);
}
});
listeningThread.IsBackground = true;
listeningThread.Start();
}
客户端
private void button1_Click(object sender, EventArgs e)
{
Connect("localhost", "hello localhost " + Guid.NewGuid());
}
static void Connect(String server, String message)
{
try
{
Int32 port = 25565;
TcpClient client = new TcpClient(server, port);
Byte[] data = System.Text.Encoding.ASCII.GetBytes(message);
NetworkStream stream = client.GetStream();
// Send the message to the connected TcpServer.
stream.Write(data, 0, data.Length);
stream.Close();
client.Close();
}
catch (ArgumentNullException e)
{
Debug.WriteLine("ArgumentNullException: {0}", e);
}
catch (SocketException e)
{
Debug.WriteLine("SocketException: {0}", e);
}
}
屏幕截图：
private static Form1 form;

{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
form = new Form1();
form.Load += OnFormLoad;
Application.Run(form);

tcpClient.Close();
}, null);
}
});
listeningThread.IsBackground = true;
listeningThread.Start();
}
创建一个线程，开始监听它&不要停止服务器
void CreateServer()
{
TcpListener tcp = new TcpListener(25565);
tcp.Start();
Thread t = new Thread(()=>
{
while (true)
{
var tcpClient = tcp.AcceptTcpClient();
ThreadPool.QueueUserWorkItem((_) =>
{
//Your server codes handling client's request.
//Don't access UI control directly here
//Use "Invoke" instead.
tcpClient.Close();
},null);
}
});
t.IsBackground = true;
t.Start();
}
这里有一个关于mdsn的好例子：您可以使用线程方法（如其他答案所述）或使用，在我的观点中，这是更好的方法。更好的是，您可以使用由提出的异步模型。
异步套接字将从使用中受益 嘿，我更新了密码，你能看一下吗？它似乎不起作用，可能是因为我是这个领域的新手。
它似乎不起作用
