  You can save the Rectangle to Memory Bitmap and then use SetPixel() method of Bitmap setting each pixel in its location then draw the whole image at its original location!

  I hope this will Help!

  I was hoping to avoid using the windows api.
  I know how to do what I want using bitblt() and other api functions.
  Yours is smaller though so I will give it a try.
  
  thanks.

  You'll need some P/Invoke to create a Graphics object to render to the display. Here's some sample code, it makes a copy of the upper-left corner of the screen and puts it back with a 10-pixel offset:
  
  [System.Runtime.InteropServices.DllImport("gdi32.dll")]
  private static extern IntPtr CreateDC(string driver, string device, IntPtr res1, IntPtr res2);
  [System.Runtime.InteropServices.DllImport("gdi32.dll")]
  private static extern bool DeleteDC(IntPtr hDc);
  
  private void button1_Click(object sender, EventArgs e) {
  Bitmap bmp = new Bitmap(100, 100);
  Graphics grb = Graphics.FromImage(bmp);
  grb.CopyFromScreen(0, 0, 0, 0, bmp.Size);
  IntPtr hdc = CreateDC("DISPLAY", "DISPLAY", IntPtr.Zero, IntPtr.Zero);
  Graphics grs = Graphics.FromHdc(hdc);
  grs.DrawImage(bmp, 10, 10);
  grs.Dispose();
  grb.Dispose();
  DeleteDC(hdc);
  }
