原文:WPF 资源（StaticResource 静态资源、DynamicResource 动态资源、添加二进制资源、绑定资源树）

一、WPF对象级（Window对象）资源的定义与查找

实例一： StaticResource 静态资源（如：皮肤配置方案，运行后不改变）

<Window x:Class="WpfApplication.Window12"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:sys="clr-namespace:System;assembly=mscorlib"

        Title="Window12" Height="300" Width="300">

    <!--将System命名空间引入到xaml代码并映射为sys命名空间-->

    <!--在Window.Resources属性添加两个资源条目-->

    <Window.Resources>

       <!--键值对资源-->

        <ResourceDictionary>

            <sys:String x:Key="str">

                字符

            </sys:String>

            <sys:Double x:Key="dbl">

                3.1415926

            </sys:Double>

        </ResourceDictionary>

    </Window.Resources>

    <StackPanel>

        <TextBlock name="textblock1" Text="{StaticResource ResourceKey=str}" Margin="5"/>

    </StackPanel>

</Window>

简化：

在C#代码中，使用定义的XAML代码中定义的资源。

            //string text = (string)FindResource("str");

            string text = (string)this.Resources["str"];//键值获取

            this.textblock1.Text = text;

实例二：把资源像CSS或JavaScript放到独立文件中。

新建 “资源字典”

Themes 文件夹中的 ShinyRed.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                    xmlns:sys="clr-namespace:System;assembly=mscorlib">

    <sys:String x:Key="str">字符</sys:String>

    <sys:Double x:Key="dbl">3.1415926</sys:Double>

</ResourceDictionary>

<Window x:Class="WpfApplication.Window12"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="Window12" Height="300" Width="300">

    <Window.Resources>

        <ResourceDictionary Source="Themes/ShinyRed.xaml"/>

    </Window.Resources>

    <StackPanel>

        <TextBlock Name="textblock1"  Margin="5" Text="{StaticResource str}"/>

    </StackPanel>

</Window>

合并多个外部资源字典成为本地字典

<Application.Resources>

<ResourceDictionary>

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="/Resources/Xml/TreeFile.xaml" />

</ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

</Application.Resources>

实例三、DynamicResource 动态资源（如：运行时，允许用户更改皮肤）

<Window x:Class="WpfApplication.Window12"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="Window12" Height="300" Width="300">

    <Window.Resources>

        <TextBlock x:Key="res1" Text="动态资源"/>

    </Window.Resources>

    <StackPanel>

        <Button Content="{DynamicResource res1}"/>

        <Button Content="Update" Click="Button_Click"/>

    </StackPanel>

</Window>

        private void Button_Click(object sender, RoutedEventArgs e)

        {

            this.Resources["res1"] = new TextBlock { Text="换皮肤"};

        }

三、向程序添加二进制资源

1、Resources.resx 文件添加字符串二进制资源

双击 Resources.resx 文件

代码：

<Window x:Class="WpfApplication.Window13"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:prop="clr-namespace:WpfApplication.Properties"

        Title="Window13" Height="300" Width="300">

    <Grid>

        <TextBox Text="{x:Static prop:Resources.UserName}"/>

    </Grid>

</Window>

2、Resources.resx 文件添加图片二进制资源

新建文件夹

设置图片属性

代码：

<Image Name="img" Source="Resources/Images/4.jpg" Stretch="Fill"/>

或者

img.Source = new BitmapImage(new Uri(@"Resources/Images/4.jpg", UriKind.Relative));

四、资源绑定树

效果：

TreeFile.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                    xmlns:s="clr-namespace:System;assembly=mscorlib"

                    >

    <XmlDataProvider x:Key="xdp" XPath="FileSystem/Folder">

        <x:XData>

            <FileSystem xmlns="">

                <Folder Name="基础设置">

                    <Folder Name="数据库地址" Value="Pages/Page_SqlAddress.xaml"/>

                    <Folder Name="配置一次图" Value="Pages/Page_ConfigControls.xaml"/>

                </Folder>

                <Folder Name="终端模板管理">

                    <Folder Name="终端管理" Value="Pages/Page_Products.xaml"/>

                    <Folder Name="终端变量管理" Value="Pages/Page_Varibles.xaml"/>

                </Folder>

                <Folder Name="配置生成">

                    <Folder Name="生成全部" Value="Pages/Page_BuildAll.xaml"/>

                    <Folder Name="单步生成-终端" Value="Pages/Page_BuildProducts.xaml"/>

                    <Folder Name="单步生成-终端变量" Value="Pages/Page_BuildVaribles.xaml"/>

                    <Folder Name="单步生成-设备" Value="Pages/Page_BuildEquipment.xaml"/>

                    <Folder Name="单步生成-一次图" Value="Pages/Page_BuildGraphical.xaml"/>

                </Folder>

            </FileSystem>

        </x:XData>

    </XmlDataProvider>

<ResourceDictionary>

App.xaml

<Application x:Class="AutomaticConfigurationAPP.App"

             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

             >

    <!--启始页等一堆参数设置，相当于控制台程序Main,是整个程序入口-->

    <Application.Resources>

        <ResourceDictionary>

            <ResourceDictionary.MergedDictionaries>

                <ResourceDictionary Source="/Resources/Xml/TreeFile.xaml" />

                <ResourceDictionary Source="pack://application:,,,/AutomaticConfigurationAPP;component/Styles/Bootstrap.xaml"/>

                <ResourceDictionary Source="pack://application:,,,/AutomaticConfigurationAPP;component/PathGeometries/Glyphicons.xaml"/>

                <!--<ResourceDictionary Source="/Themes/Theme.xaml" />-->

            </ResourceDictionary.MergedDictionaries>

        </ResourceDictionary>

    </Application.Resources>

</Application>

ViewModel层

<Window x:Class="AutomaticConfigurationAPP.MWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="配置文件自动生成工具" Height="500" Width="800" Icon="/AutomaticConfigurationAPP;component/bitbug_favicon%20%282%29.ico">

    <Window.Background>

        <ImageBrush ImageSource="/AutomaticConfigurationAPP;component/Images/background_blue.jpg" Stretch="Fill" TileMode="Tile" Viewport="0,0,1174,600" ViewportUnits="Absolute" />

    </Window.Background>

    <Grid>

        <Grid.ColumnDefinitions>

            <ColumnDefinition Width="160"/>

            <ColumnDefinition Width="2"/>

            <ColumnDefinition Width="*"/>

        </Grid.ColumnDefinitions>

        <Grid.RowDefinitions>

            <RowDefinition Height="*"/>

            <RowDefinition Height="8"/>

        </Grid.RowDefinitions>

        <TreeView  ItemsSource="{Binding Source={StaticResource xdp}}" Grid.Row="0" Grid.Column="0" x:Name="TreeRoot" Background="#E5EBF3">

            <TreeView.ItemTemplate>

                <HierarchicalDataTemplate ItemsSource="{Binding XPath=Folder}">

                        <TextBlock x:Name="a" Text="{Binding XPath=@Name}" FontSize="12"/>

                </HierarchicalDataTemplate>

            </TreeView.ItemTemplate>

        </TreeView>

        <Frame x:Name="PageContext" Grid.Row="0" Grid.Column="2"  Background="#F3F3F3" BorderBrush="#888" BorderThickness="1" NavigationUIVisibility="Visible"

               Source="{Binding ElementName=TreeRoot, Path=SelectedItem.Attributes[Value].Value}"/>

    </Grid>

</Window>
