C#-实现屏幕截取

引入命名空间：

using System.Drawing;

以下代码即可实现：

static void PrintScreen()
{
    using (Bitmap bitPic = new Bitmap(
       width: Screen.PrimaryScreen.Bounds.Width,
       height: Screen.PrimaryScreen.Bounds.Height))
    {
        using (Graphics gra = Graphics.FromImage(bitPic))
        {
            gra.CopyFromScreen(new Point(0, 0), new Point(0, 0), bitPic.Size);
            bitPic.Save("D:\\screen.bmp");
            bitPic.Dispose();
            gra.Dispose();
        }
    }
}
