使用自定义颜色代码设置面板背景

BrushConverter bc = new BrushConverter();  
stackPanelFlasher.Background=  (Brush)bc.ConvertFrom("#C7DFFC"); 

应该做这个工作。如果你想让它防水,最好是

BrushConverter bc = new BrushConverter();  
Brush brush=(Brush)bc.ConvertFrom("#C7DFFC"); 
brush.Freeze();
stackPanelFlasher.Background=brush;

需要更少的资源…

stackPanelFlasher.Background = new SolidColorBrush(Color.FromArgb(alpha, red, green, blue));

我认为这个示例对XAML解决方案有帮助;

 <Border.Background>
       <LinearGradientBrush EndPoint="1.204,0.5" StartPoint="0.056,0.5">
           <GradientStop Color="#FFFFFFFF" Offset="0" />
           <GradientStop Color="#FFD4D7DB" Offset="1" />
       </LinearGradientBrush>                     
  </Border.Background>

下面的一行程序应该可以工作。

something.Background = (Brush)new BrushConverter().ConvertFrom("#C7DFFC");
