The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code gets the color of a pixel in a bitmap, and then fills a rectangle with that color.

private void GetPixel_Example(PaintEventArgs e)
{
             
    // Create a Bitmap object from an image file.
    Bitmap myBitmap = new Bitmap("Grapes.jpg");
             
    // Get the color of a pixel within myBitmap.
    Color pixelColor = myBitmap.GetPixel(50, 50);
             
    // Fill a rectangle with pixelColor.
    SolidBrush pixelBrush = new SolidBrush(pixelColor);
    e.Graphics.FillRectangle(pixelBrush, 0, 0, 100, 100);
}
