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:
<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>
</Window.Resources>
<StackPanel>
<TextBlock name="textblock1" Text="{StaticResource str}" Margin="5"/>
</StackPanel>
</Window>
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>
<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>
<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>
