WPF Demo16 资源

<Window x:Class="RescourceDemo1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" Icon="/RescourceDemo1;component/image/test.png">
    <Window.Resources>
        <TextBlock x:Key="res1" Text="海上生明月"/>
        <TextBlock x:Key="res2" Text="海上生明月"/>
    </Window.Resources>
    <Grid>
        <Button x:Name="btnStatic" Content="{StaticResource res1}" Height="23" HorizontalAlignment="Left" Margin="211,70,0,0"  VerticalAlignment="Top" Width="75" />
        <Button x:Name="btnDynamic" Content="{DynamicResource res2}" Height="23" HorizontalAlignment="Left" Margin="211,113,0,0"  VerticalAlignment="Top" Width="75" />
        <Button Content="Update" Height="23" HorizontalAlignment="Left" Margin="212,162,0,0" Name="button3" VerticalAlignment="Top" Width="75" Click="button3_Click" />
        <Label Content="静态资源：" Height="28" HorizontalAlignment="Left" Margin="144,69,0,0" Name="label1" VerticalAlignment="Top" />
        <Label Content="动态资源：" Height="28" HorizontalAlignment="Left" Margin="144,108,0,0" Name="label2" VerticalAlignment="Top" />
        
        <Image Height="135" Source="image/test.png"  HorizontalAlignment="Left" Margin="328,50,0,0" Name="image1" Stretch="Fill" VerticalAlignment="Top" Width="150" />
    </Grid>
</Window>

using System.Windows;
using System.Windows.Controls;
 
namespace RescourceDemo1
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
 
        private void button3_Click(object sender, RoutedEventArgs e)
        {
            //静态资源一旦使用，则不变
            var res1 = this.btnStatic.Content as TextBlock;
            var res2 = this.btnDynamic.Content as TextBlock;
 
            if (res1.Text.Equals("海上生明月")) this.Resources["res1"] = new TextBlock() { Text = "天涯共此时" };
            else this.Resources["res1"] = new TextBlock() { Text = "海上生明月" };
             
            //动态资源设置后，扔可能改变
            if (res2.Text.Equals("海上生明月")) this.Resources["res2"] = new TextBlock() { Text = "天涯共此时" };
            else this.Resources["res2"] = new TextBlock() { Text = "海上生明月" };
        }
    }
}

注意：静态资源不可改变，动态资源可动态更改！ <Window.Resources>，为窗体级资源。

属性资源==》

<Window x:Class="资源1.MainWindow"
        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="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <ResourceDictionary>
            <sys:String x:Key="str">
                我是资源——资源为属性元素
            </sys:String>
        </ResourceDictionary>
    </Window.Resources>
    <Grid x:Name="grid">
        <TextBlock x:Name="textblock" Text="{StaticResource ResourceKey=str}"/>
    </Grid>

</Window>
 <!--
    在上面代码中资源为属性元素，所以<ResourceDictionary>是可以省略掉的，下面是在后台的等效代码：
          this.Resources["str1"] = "我是资源";
          this.textblock.Text = this.FindResource("str1") as string;
-->

静态、动态资源(资源为属性元素)==》

<Window x:Class="资源2.MainWindow"
        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="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <sys:String x:Key="DynamicRes">动态资源</sys:String>
        <sys:String x:Key="StaticRes">静态资源</sys:String>
    </Window.Resources>
    <StackPanel>
        <TextBox x:Name="txt1" Text="{DynamicResource ResourceKey=DynamicRes}" Margin="10"/>
        <TextBox x:Name="txt2" Text="{StaticResource ResourceKey=StaticRes}" Margin="10"/>
        <Button x:Name="btn" Content="资源类型区分" Click="btn_Click_1" Height="25" Margin="5"/>
    </StackPanel>
</Window>

using System.Windows;
 
namespace 资源2
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
 
        private void btn_Click_1(object sender, RoutedEventArgs e)
        {
            this.Resources["StaticRes"] += "静态资源发生";
            this.Resources["DynamicRes"] += "改变";
        }
    }
}

窗体级、文件级、应用程序级、对象级资源==》

项目结构：

App.xml==》

<Application x:Class="资源3.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <SolidColorBrush Color="Gold" x:Key="myGoldBrush" />
    </Application.Resources>
</Application>


文件资源==》
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <SolidColorBrush x:Key="myWhiteBrush" Color="White" />
</ResourceDictionary>

用法如下：

<Window x:Class="资源3.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <!--窗体级资源-->
        <!--<SolidColorBrush x:Key="myRedBrush" Color="Red" />-->

        <ResourceDictionary>
            <SolidColorBrush x:Key="myRedBrush" Color="Red" />
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Dictionary1.xaml"></ResourceDictionary>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
        <!--文件级资源-->
        <!--<ResourceDictionary x:Key="aa"  Source="Dictionary1.xaml"/>-->
    </Window.Resources>

    <StackPanel>
        <!--窗体级资源-->
        <Button Margin="5" Background="{StaticResource myRedBrush}">窗体级资源Button</Button>
        <!--应用程序级资源-->
        <Button Margin="5" Background="{StaticResource myGoldBrush}">应用程序级资源Button</Button>
        <!--文件级资源-->
        <Button Margin="5" Background="{StaticResource myWhiteBrush}">文件级资源Button</Button>
        <!--对象级资源-->
        <Button Margin="5">
            <Button.Resources>
                <SolidColorBrush x:Key="myGreenBrush" Color="Green" />
            </Button.Resources>
            <Button.Content>
                <TextBlock Text="Sample Text" Background="{StaticResource myGreenBrush}" />
            </Button.Content>
        </Button>
    </StackPanel>
</Window>

        <Button Margin="5" Content="窗体级资源的值覆盖应用程序级资源的值" Background="{StaticResource myBrush}" /> 
        <StackPanel Background="#FF999999">
            <StackPanel.Resources>
                <!-- 对象级资源 --> 
                <SolidColorBrush Color="Yellow" x:Key="myYellowBrush" /> 
                <SolidColorBrush Color="Red" x:Key="myBrush" /> 
            </StackPanel.Resources> 
            <!-- 使用应用程序级定义的资源 -->
            <Button Margin="5" Content="使用应用程序级定义的资源" Background="{StaticResource myGoldBrush}" />

            <!-- 使用对象级定义的资源覆盖窗体级、应用程序级定义的资源 -->
            <Button Margin="5" Content="使用对象级定义的资源覆盖窗体级、应用程序级定义的资源" Background="{StaticResource myBrush}" /> 
        </StackPanel>

</Window>
