1、String轉換成Color

            Color color = (Color)ColorConverter.ConvertFromString(string);

2、String轉換成Brush

            BrushConverter brushConverter = new BrushConverter();
            Brush brush = (Brush)brushConverter.ConvertFromString(string);

3、Color轉換成Brush

            Brush brush = new SolidColorBrush(color));

4、Brush轉換成Color有兩種方法：

（1）先將Brush轉成string，再轉成Color。

            Color color= (Color)ColorConverter.ConvertFromString(brush.ToString());

（2）將Brush轉成SolidColorBrush，再取Color。

            Color color= ((SolidColorBrush)CadColor.Background).Color;
