同じの短いバージョンを試すこともできます:
public class BooleanAndConverter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return values.OfType<IConvertible>().All(System.Convert.ToBoolean);
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotSupportedException();
}
}
public class BooleanOrConverter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return values.OfType<IConvertible>().Any(System.Convert.ToBoolean);
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotSupportedException();
}
}
もちろん、可視性のためにコンバーターも必要になる場合があります。
public class BooleanOrToVisibilityConverter : IMultiValueConverter
{
public Visibility HiddenVisibility { get; set; }
public bool IsInverted { get; set; }
public BooleanOrToVisibilityConverter()
{
HiddenVisibility = Visibility.Collapsed;
IsInverted = false;
}
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
bool flag = values.OfType<IConvertible>().Any(System.Convert.ToBoolean);
if (IsInverted) flag = !flag;
return flag ? Visibility.Visible : HiddenVisibility;
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
public class BooleanAndToVisibilityConverter : IMultiValueConverter
{
public Visibility HiddenVisibility { get; set; }
public bool IsInverted { get; set; }
public BooleanAndToVisibilityConverter()
{
HiddenVisibility = Visibility.Collapsed;
IsInverted = false;
}
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
bool flag = values.OfType<IConvertible>().All(System.Convert.ToBoolean);
if (IsInverted) flag = !flag;
return flag ? Visibility.Visible : HiddenVisibility;
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
