WPF 屏蔽DPI改变对程序的影响的解决方案

Converter: 
[ValueConversion(typeof(object), typeof(object))]
   public class DPIConverter : IValueConverter
   {
       public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
       {
           WindowInteropHelper winHelper = new WindowInteropHelper((MainWindow)App.Current.MainWindow);
           IntPtr mainWindowHandle = winHelper.Handle;
           Graphics currentGraphics = Graphics.FromHwnd(mainWindowHandle);
           double currentDpiX = currentGraphics.DpiX;
           double dpiXRatio = currentDpiX / 96;  
         
            if (targetType == typeof(GridLength))
           {
               double data = double.Parse(parameter.ToString());
 
                GridLength gridLength = new GridLength(data / dpiXRatio, GridUnitType.Pixel);
               return gridLength;
           }
           if (targetType == typeof(Thickness))
           {
               Thickness margin = (Thickness)parameter;
               if (margin != null)
               {
                   margin.Top = margin.Top / dpiXRatio;
                   margin.Left = margin.Left / dpiXRatio;
                   margin.Right = margin.Right / dpiXRatio;
                   margin.Bottom = margin.Bottom / dpiXRatio;
                   return margin;
               }
           }
           if (targetType == typeof(double))
           {
               double fontSize = double.Parse(parameter.ToString());
               return fontSize / dpiXRatio;
           }
           if(targetType==typeof(System.Windows.Point))
           {

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
