WPF使用资源字典组织资源

转载：http://blog.163.com/wangzhenguo2005@126/blog/static/371405262010111413321728/

首先在解决方案资源管理器中添加一个或多个资源词典（资源字典），并向多个资源字典中添加对象资源信息。示例中新建了三个资源字典，并向资源字典中添加了对象资源，代码如下。

第一个资源字典：(第一个资源字典命名为MyDictionary1.xaml)

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ImageBrush x:Key="MyBrush1"
                TileMode="Tile"
                ViewportUnits="Absolute"
                Viewport="0 0 30 30"
                ImageSource="/image/1.png"
                Opacity="0.9"/>
</ResourceDictionary>

第二个资源字典：(第二个资源字典命名为MyDictionary2.xaml)

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <LinearGradientBrush x:Key="MyBrush2">
        <LinearGradientBrush.GradientStops>
            <GradientStopCollection>
                <GradientStop Color="Red" Offset="0.1"/>
                <GradientStop Color="Green" Offset="0.5"/>
                <GradientStop Color="Blue" Offset="0.9"/>
            </GradientStopCollection>
        </LinearGradientBrush.GradientStops>
    </LinearGradientBrush>
</ResourceDictionary>

第三个资源字典：(第三个资源字典命名为MyDictionary3.xaml)

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <SolidColorBrush x:Key="MyBrush3" Color="Blue"/>
</ResourceDictionary>

在创建了多个资源字典后可以将它们合并到主窗体的资源集合中，示例代码如下。

<Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="MyDictionary1.xaml"/>
                <ResourceDictionary Source="MyDictionary2.xaml"/>
                <ResourceDictionary Source="Mydictionary3.xaml"/>
            </ResourceDictionary.MergedDictionaries>
            <ImageBrush x:Key="MyBrush"
                    TileMode="Tile"
                    ViewportUnits="Absolute"
                    Viewport="0 0 50 50"
                    ImageSource="/image/1.png"
                    Opacity="0.9"/>
        </ResourceDictionary>
    </Window.Resources>

将多个资源字典和并到窗体资源集合后，就可以像使用窗体中定义的资源一下使用多个资源字典中的资源了，示例代码如下。

<Window x:Class="WPF中的对象集合.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300">
    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="MyDictionary1.xaml"/>
                <ResourceDictionary Source="MyDictionary2.xaml"/>
                <ResourceDictionary Source="Mydictionary3.xaml"/>
            </ResourceDictionary.MergedDictionaries>
            <ImageBrush x:Key="MyBrush"
                    TileMode="Tile"
                    ViewportUnits="Absolute"
                    Viewport="0 0 50 50"
                    ImageSource="/image/1.png"
                    Opacity="0.9"/>
        </ResourceDictionary>
    </Window.Resources>
    <Grid>
        <Button Background="{StaticResource MyBrush1}"></Button>
    </Grid>
</Window>
