C#窗体程序，点击按钮通过MAC地址远程TCP协议网络唤醒电脑主机的完整代码

在C#中，通过按钮点击实现MAC地址的远程TCP唤醒计算机主机涉及到几个关键步骤，包括网络连接、发送数据以及操作系统级别的命令执行。由于Windows API提供了用于远程控制的功能，我们可以使用`ManagementObjectSearcher`来发送Wake-on-LAN信号。以下是一个简化的示例代码片段，注意这只是一个基础的框架，并未包含完整的错误处理和异常管理：

using System;
using System.Management;
using System.Net.NetworkInformation;

public partial class Form1 : Form
{
    private static readonly byte[] MagicPacket = new byte[6] { 0xff, 0xff, 0xff, 0xff, 0xff, 0xd0 };

    private void buttonSend_Click(object sender, EventArgs e)
    {
        string ipAddress = "your_computer_ip_address";
        if (string.IsNullOrEmpty(ipAddress))
            return;

        // 获取目标设备的MAC地址
        ManagementObjectSearcher searcher = new ManagementObjectSearcher($"select * from Win32_NetworkAdapterConfiguration where IPAddress='{ipAddress}'");
        ManagementObject targetAdapter = searcher.Get()[0];
        string macAddress = targetAdapter.Properties["MacAddress"].Value.ToString();

        try
        {
            // 构建魔力包（针对特定MAC地址）
            foreach (byte b in macAddress.HexToByteArray())
                MagicPacket[5] = b;

            // 连接到服务器端并发送数据
            using (TcpClient client = new TcpClient())
            {
                client.Connect(ipAddress, 9);
                NetworkStream stream = client.GetStream();
                stream.Write(MagicPacket, 0, MagicPacket.Length);
                stream.Close();
                client.Close();
                MessageBox.Show("Wake-on-LAN signal sent to the specified computer.");
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show($"Failed to send Wake-on-LAN: {ex.Message}");
        }
    }
}
