Cómo obtener el color que esta debajo del cursor del mouse en C#

#csharp #design

Para obtener el color de bajo del cursor del mouse solo agregamos este código al formulario

[DllImport("user32.dll")] private static extern bool GetCursorPos(ref Point lpPoint); [DllImport("gdi32.dll", CharSet = CharSet.Auto, SetLastError = true, ExactSpelling = true)] public static extern int BitBlt(IntPtr hDC, int x, int y, int nWidth, int nHeight, IntPtr hSrcDC, int xSrc, int ySrc, int dwRop);
Enter fullscreen mode Exit fullscreen mode

Importamos todas las librerías necesaria.

Primero obtenemos la pantalla

Bitmap screenPixel = new Bitmap(1, 1, PixelFormat.Format32bppArgb);
Enter fullscreen mode Exit fullscreen mode

Y creamos este método para obtener el color

 public Color GetColor(Point location) { using (Graphics gdest = Graphics.FromImage(screenPixel)) { using (Graphics gsrc = Graphics.FromHwnd(IntPtr.Zero)) { IntPtr hSrcDC = gsrc.GetHdc(); IntPtr hDC = gdest.GetHdc(); int retval = BitBlt(hDC, 0, 0, 1, 1, hSrcDC, location.X, location.Y, (int)CopyPixelOperation.SourceCopy); gdest.ReleaseHdc(); gsrc.ReleaseHdc(); } } return screenPixel.GetPixel(0, 0); }
Enter fullscreen mode Exit fullscreen mode
