WPF ValueConversion -2-

索引表示

変換に Sin() を使用する。やはりこうでないと。





namespace ValueCVT

{

    [ValueConversion(typeof(Double), typeof(Double))]

    public class DataConverter : IValueConverter

    {

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

        {

            //  ⇒方向の変換

            Double z_forward = (Double)value;

            return (Math.Sin(z_forward*3.1415/180)*1000);

        }

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

        {

            //  ←方向の変換（逆方向）

            Double z_rewind = (Double)value/1000;

            Double z_rad = Math.Asin(z_rewind);

            z_rewind = z_rad*180/3.1415;

            return z_rewind;

        }

    }

}
