我就废话不多说了，大家还是直接看代码吧~

//from MaterialDesignDemo.Converters public class BrushToHexConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (value == null) return null; string lowerHexString(int i) => i.ToString("X2").ToLower(); var brush = (SolidColorBrush)value; var hex = lowerHexString(brush.Color.R) + lowerHexString(brush.Color.G) + lowerHexString(brush.Color.B); return "#" + hex; } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } }

补充：C# 16进制转 Brush 颜色对象

代码图如下：

代码片如下：

BrushConverter brushConverter = new BrushConverter(); PopupBorder.Background = (Brush)brushConverter.ConvertFromString("#121212"); MessageLabel.Foreground = (Brush)brushConverter.ConvertFromString("#7d7d7d");

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。如有错误或未考虑完全的地方，望不吝赐教。
