1、String转换成Color

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

2、String转换成Brush

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

3、Color转换成Brush

            Brush brush = new SolidColorBrush(color));

4、Brush转换成Color有两种方法:

(1)先将Brush转成string,再转成Color。

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

(2)将Brush转成SolidColorBrush,再取Color。

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