如何为测试目的模拟网络故障(在C#中)？

using System.Net.Sockets;

Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socket.ReceiveTimeout = 1000; // 设置接收超时为1000毫秒

try
{
    socket.Connect("example.com", 80);
}
catch (SocketException ex)
{
    Console.WriteLine("连接失败: " + ex.Message);
}

if (socket.Connected)
{
    byte[] sendBuffer = Encoding.UTF8.GetBytes("GET / HTTP/1.1\r\nHost: example.com\r\n\r\n");
    byte[] receiveBuffer = new byte[1024];

    try
    {
        socket.Send(sendBuffer);
        int bytesReceived = socket.Receive(receiveBuffer);
        Console.WriteLine("接收到的数据: " + Encoding.UTF8.GetString(receiveBuffer, 0, bytesReceived));
    }
    catch (SocketException ex)
    {
        Console.WriteLine("接收数据失败: " + ex.Message);
    }
}

socket.Close();
