WPF通过DynamicResource的用法

1.先在资源类库中编写：style.xaml，如下：

<ResourceDictionary

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

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

 

  <!-- Background Style -->

  <Style x:Key="styleBackground">

    <Setter Property="Control.Background">

      <Setter.Value>

        <LinearGradientBrush StartPoint="0,0.5" EndPoint="1,0.5" Opacity="0.5">

          <GradientStop Color="LightSkyBlue" Offset="0" />

          <GradientStop Color="WhiteSmoke" Offset="0.5" />

          <GradientStop Color="LightSkyBlue" Offset="1" />

        </LinearGradientBrush>

      </Setter.Value>

    </Setter>

  </Style>

 

  <!-- Banner Style -->

  <Style x:Key="styleBanner">

    <Setter Property="StackPanel.Background">

      <Setter.Value>

        <LinearGradientBrush StartPoint="0,0.25" EndPoint="1,0.5">

          <GradientStop Color="#CC0088DD" Offset="0.3" />

          <GradientStop Color="#3300FFFF" Offset="0.85" />

        </LinearGradientBrush>

      </Setter.Value>

    </Setter>

    <Setter Property="TextBlock.Foreground" Value="Yellow" />

    <Setter Property="TextBlock.FontFamily" Value="Comic Sans MS" />

  </Style>

</ResourceDictionary>

 

2.在App.xaml类中，声明引用类型，

 <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>

                <ResourceDictionary Source="pack://application:,,,/Resource;component/Styles/Style.xaml" />
            </ResourceDictionary.MergedDictionaries>

        </ResourceDictionary>

 </Application.Resources>

 

3.在window、UserControl当中，直接使用动态资源，如下：

<Window  x:Class="SkinnableApp.MainWindow"

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

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

  xmlns:scm="clr-namespace:System.ComponentModel;assembly=WindowsBase"

 

  SizeToContent="Height"

  ResizeMode="NoResize"

  Width="680"

  WindowStartupLocation="CenterScreen"

  WindowStyle="ToolWindow">

  <Grid x:Name="Root" Style="{DynamicResource styleBackground}">

    <!-- BANNER -->

    <Grid Height="70" Style="{DynamicResource styleBanner}" >

      <TextBlock FontSize="26" Padding="10,0,10,0" Text="Insurance Agent Management System" VerticalAlignment="Center"/>

    </Grid>

</Window>
