using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace MonitorControl
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        public int WM_SYSCOMMAND = 0x0112;
        public int SC_MONITORPOWER = 0xF170;

        [DllImport("user32.dll")]
        private static extern int SendMessage(int hWnd, int hMsg, int wParam,
int lParam);

        private void button1_Click(object sender, EventArgs e)
        {
            SendMessage(this.Handle.ToInt32(), WM_SYSCOMMAND,
SC_MONITORPOWER, 2);
        }
    }
}

拖一個按鈕控制項...加入 Click 事件...就 OK 了...:D
