我正在学习如何使用异步 tcp 套接字服务器/客户端
无法弄清楚为什么我的服务器没有继续监听客户端发送的数据...消息框只出现一次，然后我需要重新打开服务器
这是我的代码（客户端）
public partial class Form1 : Form
{
private Socket client;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
try
{
client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
client.BeginConnect(new IPEndPoint(IPAddress.Loopback, 8888), new AsyncCallback(ConnectCallback), null);
}
catch
{
}
}
private void ConnectCallback(IAsyncResult AR)
{
try
{
client.EndConnect(AR);
}
catch
{
}
}
private void SendCallback(IAsyncResult AR)
{
try
{
client.EndSend(AR);
}
catch
{
}
}
private void button1_Click(object sender, EventArgs e)
{
byte[] buffer = Encoding.ASCII.GetBytes("Hello World!");
client.BeginSend(buffer, 0, buffer.Length, 0, new AsyncCallback(SendCallback), null);
}
}
服务器
private Socket sck, sckc;
private byte[] buffer;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
try
{
sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
sck.Bind(new IPEndPoint(IPAddress.Any, 8888));
sck.Listen(0);
sck.BeginAccept(new AsyncCallback(AcceptCallback), null);
}
catch
{
}
}
private void AcceptCallback(IAsyncResult AR)
{
try
{
while (true)
{
sckc = sck.EndAccept(AR);
buffer = new byte[sckc.ReceiveBufferSize];
sckc.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveCallback), null);
}
}
catch
{
}
}
private void ReceiveCallback(IAsyncResult AR)
{
try
{
string text = Encoding.ASCII.GetString(buffer);
MessageBox.Show(text);
}
catch
{
}
}
