截取电脑全屏

private void button2_Click(object sender, EventArgs e)
{
     Bitmap myImage = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
     Graphics g = Graphics.FromImage(myImage);
     g.CopyFromScreen(new Point(0, 0), new Point(0, 0), new Size(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height));
     IntPtr dc1 = g.GetHdc();
     g.ReleaseHdc(dc1);
     myImage.Save(@"c:\screen0.jpg");
}

截取窗体屏幕

private void button3_Click(object sender, EventArgs e)
{
     Bitmap myImage = new Bitmap(this.Width, this.Height);
     Graphics g = Graphics.FromImage(myImage);
     g.CopyFromScreen(new Point(this.Location.X, this.Location.Y), new Point(0, 0), new Size(this.Width, this.Height));
     IntPtr dc1 = g.GetHdc();
     g.ReleaseHdc(dc1);
     myImage.Save(@"c:\screen1.jpg");
 }
