Using a StaticResource SolidColorBrush to define the Gradient Stop Colors
提问by code-zoop
I am creating some wpf resource dictionaries with all the styles for an application! I have a few LinearGradientBrushes, where the color is set directly in the LinearGradientBrushreference as GradientStops. However, I want to have a predefined set of colors that I can use a a reference for each GradientStop, so that changing the color scheme for the application is a matter of changing the values of the SolidColorBrushes:
我正在创建一些 wpf 资源字典，其中包含应用程序的所有样式！我有几个LinearGradientBrushes，其中颜色直接在LinearGradientBrush参考中设置为GradientStops。但是，我想要一组预定义的颜色，我可以为每个颜色使用参考GradientStop，这样更改应用程序的配色方案就是更改SolidColorBrushes的值的问题：
<SolidColorBrush Color="#5A5A5A" x:Key="colorbrushMedium" />
<SolidColorBrush Color="#222222" x:Key="colorbrushDark" />
<LinearGradientBrush>
<GradientStop Color="{StaticResource colorbrushMedium}"/>
<GradientStop Color="{StaticResource colorbrushDark}" Offset="1"/>
</LinearGradientBrush>
With the code example above, I am getting the following error:
使用上面的代码示例，我收到以下错误：
Cannot convert the value in attribute 'Color' to object of type 'System.Windows.Media.Color'. '#5A5A5A' is not a valid value for property 'Color'.
The line it refers to is the line where <GradientStop Color="{StaticResource colorbrushMedium}"/>is defined.
它所指的行<GradientStop Color="{StaticResource colorbrushMedium}"/>是定义所在的行。
Any ideas?
有任何想法吗？

Ok, I found the problem:
好的，我发现了问题：
Using Color and not SolidColorBrush..
使用 Color 而不是 SolidColorBrush ..
<Color x:Key="colorbrushMedium">#FF5A5A5A</Color>
<Color x:Key="colorbrushDark">#FF222222</Color>
<LinearGradientBrush>
<GradientStop Color="{StaticResource colorbrushMedium}"/>
<GradientStop Color="{StaticResource colorbrushDark}" Offset="1"/>
</LinearGradientBrush>
This seems to solve my problem!
这似乎解决了我的问题！

Use Bindingto reference the color both in SolidColorBrushand in LinearGradientBrush:
使用Binding引用的颜色都在SolidColorBrush和LinearGradientBrush：
<SolidColorBrush x:Key="stop1" Color="#FF5A5A5A"/>
<SolidColorBrush x:Key="stop2" Color="#FF222222"/>
<LinearGradientBrush x:Key="gradient">
<GradientStop Color="{Binding Source={StaticResource stop1},Path=Color}" Offset="0"/>
<GradientStop Color="{Binding Source={StaticResource stop2},Path=Color}" Offset="1"/>
</LinearGradientBrush>
