WPF造型颜色

Question

I want to do something like this:

<Color x:Key="clrPrimary">#5381ac</Color>
<Color x:Key="clrSecondary">#20558a</Color>

<Style TargetType="Grid" x:Key="myGrid">
    <Setter Property="Background" Value="{StaticResource clrPrimary"/>
</Style>

'#FF5381AC' is not a valid value for property 'Background'.

Having trouble nailing it down, can any one point me in the right direction?

Answer 1

Background is a Brush , not a Color . Your best bet is to define your "Primary" and "Secondary" resources as brushes rather than colours.

Pretty sure you could even base the brushes off your existing colours.

<SolidColorBrush x:Key="PrimaryBrush" Color="{StaticResource clrPrimary}" />
...
    <Setter Property="Background" Value="{StaticResource PrimaryBrush}" />

Answer 2

The background property needs a brush to work.

<Window.Resources>
    <SolidColorBrush x:Key="clrPrimary" Color="#5381ac" />
</Window.Resources>

Answer 3

Background属性的类型为System.Windows.Media.Brush ，而不是Color。
