MergedDictionaries(学习)

创建Resource的时候我们一般在本Solution根目录下右键创建新的resource文件，is just a collection of any typed objects, not elements.

比如：

1 <LinearGradientBrush EndPoint="1,0" x:Key="brush1">

2 <GradientStop Color="Yellow" Offset="0" />

3 <GradientStop Color="Orange" Offset=".7" />

4 <GradientStop Color="DarkRed" Offset="1" />

5 </LinearGradientBrush>

View Code

其他xaml文件（MainWindow.xaml或者某个view）要使用它的时候

<Ellipse Fill="{StaticResource brush1}" />

但是之前记得在<Application.Resources>级，或者本级merge这个资源

如下Open App.xaml. inside the <Application.Resources> tag加入下面

1 <ResourceDictionary>

2 <ResourceDictionary.MergedDictionaries>

3 <ResourceDictionary Source="Brushes.xaml" />

4 </ResourceDictionary.MergedDictionaries>

5 </ResourceDictionary>

View Code

 

注意：

1. Merge的source要写清楚Path：
   

   1 <ResourceDictionary>
   
   2 <ResourceDictionary.MergedDictionaries>
   
   3 <ResourceDictionary Source="Brushes.xaml" />
   
   4 </ResourceDictionary.MergedDictionaries>
   
   5 </ResourceDictionary>

   View Code

   if 资源在Resources文件夹下, merging that into App.xaml would look like as follows:

   <ResourceDictionary Source="Resources/Brushes.xaml" />

    

2. 对于在其他referenced assemblies. 要Base on pack URI syntax.比如：

   <ResourceDictionary Source="/MyClassLibrary;component/Resources/
   
   Brushes.xaml" />

    

3. 对于Duplicat的资源，排序原则。有写内部Key的先，然后是最后一个resource里定义过的笔刷，然后是倒出第二个
   

   <ResourceDictionary>
   
   <SolidColorBrush Color="Blue" x:Key="brush1" />
   
   <ResourceDictionary.MergedDictionaries>
   
   <ResourceDictionary Source="Resources/Brushes2.xaml" />
   
   <ResourceDictionary Source="Resources/Brushes.xaml" />
   
   </ResourceDictionary.MergedDictionaries>
   
   </ResourceDictionary>
