如何在C#中取消/中止TCP请求

TcpClient client = new TcpClient();
client.Connect(serverIP, serverPort);

CancellationTokenSource cts = new CancellationTokenSource();

NetworkStream stream = client.GetStream();
byte[] data = Encoding.ASCII.GetBytes(request);

// 异步发送请求
Task sendTask = stream.WriteAsync(data, 0, data.Length, cts.Token);

// 在需要取消请求时调用
cts.Cancel();

try
{
    await sendTask;
    // 请求发送成功
}
catch (OperationCanceledException)
{
    // 请求被取消
}
catch (Exception ex)
{
    // 其他异常处理
}
