{
public class Program
{
enum RasterOperation : uint { SRC_COPY = 0x00CC0020 }
[DllImport("coredll.dll")]
static extern int BitBlt(IntPtr hdcDest, int nXDest, int nYDest, int nWidth, int nHeight, IntPtr hdcSrc, int nXSrc, int nYSrc, RasterOperation rasterOperation);
[DllImport("coredll.dll")]
private static extern IntPtr GetDC(IntPtr hwnd);
[DllImport("coredll.dll")]
private static extern int ReleaseDC(IntPtr hwnd, IntPtr hdc);
static void Main(String[] args)
{
Rectangle bounds = Screen.PrimaryScreen.Bounds;
IntPtr hdc = GetDC(IntPtr.Zero);
Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height, PixelFormat.Format16bppRgb565);
using (Graphics graphics = Graphics.FromImage(bitmap))
{
IntPtr dstHdc = graphics.GetHdc();
BitBlt(dstHdc, 0, 0, bounds.Width, bounds.Height, hdc, 0, 0,
RasterOperation.SRC_COPY);
graphics.ReleaseHdc(dstHdc);
}
bitmap.Save("screenshot.jpg", ImageFormat.Jpeg);
ReleaseDC(IntPtr.Zero, hdc);
}
}

Use OpenNetCF SDF

// create a bitmap and graphics objects for the capture
Drawing.Bitmap destinationBmp = new Drawing.Bitmap(Forms.Screen.PrimaryScreen.Bounds.Width, Forms.Screen.PrimaryScreen.Bounds.Height);
Drawing.Graphics g = Drawing.Graphics.FromImage(destinationBmp);
GraphicsEx gx = GraphicsEx.FromGraphics(g);
// capture the current screen
gx.CopyFromScreen(0, 0, 0, 0, Forms.Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy);
// save the file
destinationBmp.Save(filename, System.Drawing.Imaging.ImageFormat.Png);
// clean house
gx.Dispose();
g.Dispose();
destinationBmp.Dispose();
