在C#腳本中進行網(wǎng)絡通信通常使用Socket類或HttpWebRequest類。以下是一個簡單的示例,演示如何使用Socket類進行網(wǎng)絡通信:

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;

class Program
{
    static void Main()
    {
        string host = "www.example.com";
        int port = 80;

        // 創(chuàng)建Socket對象
        Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

        // 連接到服務器
        socket.Connect(IPAddress.Parse(host), port);

        // 發(fā)送數(shù)據(jù)
        string requestData = "GET / HTTP/1.1\r\nHost: " + host + "\r\n\r\n";
        byte[] data = Encoding.ASCII.GetBytes(requestData);
        socket.Send(data);

        // 接收響應
        byte[] buffer = new byte[1024];
        int bytesReceived = socket.Receive(buffer);
        string responseData = Encoding.ASCII.GetString(buffer, 0, bytesReceived);
        Console.WriteLine(responseData);

        // 關閉連接
        socket.Close();
    }
}

另外,如果要進行HTTP請求,可以使用HttpWebRequest類。以下是一個簡單的示例:

using System;
using System.Net;

class Program
{
    static void Main()
    {
        string url = "http://www.example.com";

        // 創(chuàng)建HttpWebRequest對象
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

        // 發(fā)送請求并獲取響應
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
        {
            using (System.IO.Stream stream = response.GetResponseStream())
            {
                using (System.IO.StreamReader reader = new System.IO.StreamReader(stream))
                {
                    string responseData = reader.ReadToEnd();
                    Console.WriteLine(responseData);
                }
            }
        }
    }
}

以上示例演示了如何使用Socket類和HttpWebRequest類進行網(wǎng)絡通信。在實際應用中,你可能需要根據(jù)具體需求來選擇合適的網(wǎng)絡通信方式。
