.NET 屏幕截图

屏幕截屏

截屏并赋值给pictureBox1进行显示:

Bitmap bm = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
Graphics g = Graphics.FromImage(bm);
g.CopyFromScreen(0, 0, 0, 0, bm.Size);

pictureBox1.Image = bm;

如果想连续截屏以每秒3FPS效果可以这样做:

new Thread(() =>
{
    while (true)
    {
        Bitmap bm = new Bitmap(Screen.PrimaryScreen.Bounds.Width,       
        Screen.PrimaryScreen.Bounds.Height);
        Graphics g = Graphics.FromImage(bm);
        g.CopyFromScreen(0, 0, 0, 0, bm.Size);

        pictureBox1.Image = bm;
        Thread.Sleep(1000 / 3);
    }
}).Start();
