Что я использую в своем приложении, оно работает на несколько дисплеев и на другую установку
//center a window on chosen screen
public static void CenterWindow(Window w, System.Windows.Forms.Screen screen = null)
{
if(screen == null)
screen = System.Windows.Forms.Screen.PrimaryScreen;
int screenW = screen.Bounds.Width;
int screenH = screen.Bounds.Height;
int screenTop = screen.Bounds.Top;
int screenLeft = screen.Bounds.Left;
w.Left = PixelsToPoints((int)(screenLeft + (screenW - PointsToPixels(w.Width, "X")) / 2), "X");
w.Top = PixelsToPoints((int)(screenTop + (screenH - PointsToPixels(w.Height, "Y")) / 2), "Y");
}
public static double PixelsToPoints(int pixels, string direction)
{
if (direction == "X")
{
return pixels * SystemParameters.WorkArea.Width / System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Width;
}
else
{
return pixels * SystemParameters.WorkArea.Height / System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height;
}
}
public static double PointsToPixels(double wpfPoints, string direction)
{
if (direction == "X")
{
return wpfPoints * System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Width / SystemParameters.WorkArea.Width;
}
else
{
return wpfPoints * System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height / SystemParameters.WorkArea.Height;
}
}
