1、使用Win32的API接口 ：SendMessage 2、基于C# 任务台代码如下 class Program { public const uint WM_SYSCOMMAND = 0x0112; public const uint SC_MONITORPOWER = 0xF170; [DllImport("user32")] public static extern IntPtr SendMessage(IntPtr hWnd, uint wMsg, uint wParam, int lParam); private static readonly IntPtr HWND_BROADCAST = new IntPtr(0xffff); static void CloseLCD() { SendMessage(HWND_BROADCAST, WM_SYSCOMMAND, SC_MONITORPOWER, 2); // 2 为关闭显示器， －1则打开显示器 } static void OpenLCD() { SendMessage(HWND_BROADCAST,...
