You can try this code


internal void CaptureScreen()
{
Graphics g1 = CreateGraphics();
Image MyImage = new Bitmap(ClientRectangle.Width,
ClientRectangle.Height, g1);
Graphics g2 = Graphics.FromImage(MyImage);
IntPtr dc1 = g1.GetHdc();
IntPtr dc2 = g2.GetHdc();
BitBlt(dc2, 0, 0, ClientRectangle.Width,
ClientRectangle.Height, dc1, 0, 0, 13369376);
g1.ReleaseHdc(dc1);
g2.ReleaseHdc(dc2);
MyImage.Save(@"Captured.jpg", ImageFormat.Jpeg);
}
[System.Runtime.InteropServices.DllImportAttribute( "gdi32.dll")]
private static extern bool BitBlt(
IntPtr hdcDest,
int nXDest
int nYDest
int nWidth
int nHeight
IntPtr hdcSrc
int nXSrc
int nYSrc
Int32 dwRop
);
