我的 Windows.Resources 添加了以下样式

<Window.Resources>
...
<!--A Style that extends the previous TextBlock Style-->
<!--This is a "named style" with an x:Key of TitleText-->
<Style BasedOn="{StaticResource {x:Type TextBlock}}"
   TargetType="TextBlock"
   x:Key="TitleText">
<Setter Property="FontSize" Value="26"/>
<Setter Property="Foreground">
 <Setter.Value>
  <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1">
    <LinearGradientBrush.GradientStops>
      <GradientStop Offset="0.0" Color="#90DDDD" />
      <GradientStop Offset="1.0" Color="#5BFFFF" />
    </LinearGradientBrush.GradientStops>
  </LinearGradientBrush>
  </Setter.Value>
</Setter>
</Style> 
...
</Window.Resources>

我的 xaml 代码中有很多这样的样式,我想将每个组件样式保存到一个额外的文件(不是外部文件)中。例如,与 TextBlocks 相关的所有样式都应该在一个名为TextBlockStyles.xaml

我将如何在 wpf 中执行此操作?

如何在我的项目中链接样式?

您使用合并的资源字典

在你 app.xaml 你会使用

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary 
                Source="/Your.Assembly.Name;component/TextBlockStyles.xaml"/>
            ... other dictionaries here
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

或直接进入 UserControl 将是

<UserControl.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary 
                Source="/Your.Assembly.Name;component/TextBlockStyles.xaml"/>
            ... other dictionaries here
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</UserControl.Resources>

如果文件位于同一程序集和项目的根目录中,或者将资源字典放入文件夹中,则可以缩短Source="..."为。Source="TextBlockStyles.xaml"Source="Styles\TextBlockStyles.xaml"Styles

MyView.xaml用例:您有一个使用按钮调用的用户控件。您想使用外部 XAML 文件设置按钮样式。


MyView.xaml

<User Control ...namespaces...>
    <UserControl.Resources>
        <ResourceDictionary>
            ...converters...

            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="MyButton.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </UserControl.Resources>

     ...the rest of the control...
</UserControl>

MyButton.xaml

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:MSDNSample">

    <Style x:Key="FooButton" TargetType="{x:Type Button}">
        <Setter Property="Background" Value="Pink" />
    </Style>
</ResourceDictionary>

回到MyView.xaml(“控件的其余部分”):

<Button Style="{StaticResource FooButton}">
    Hello World
</Button>

解决方案资源管理器中右键单击您的项目选择添加然后单击资源字典... 选择名称并添加到您的项目。打开App.xaml在应用程序标记 中添加此代码

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="YourStyle.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

在 YourStyle.xaml 中:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:local="clr-namespace:APPNAME">
    <Style x:Key="ButtonStyle" TargetType="{x:Type Button}">
        <Setter Property="Background" Value="Pink" />
    </Style>
</ResourceDictionary>

您正在寻找动态资源。最好的方法是在资源中加载和标记字典。应用程序或在控制页面上。这是一个很好的示例。

http://blogs.msdn.com/b/wpfsdk/archive/2007/06/08/defining-and-using-shared-resources-in-a-custom-control-library.aspx

<ResourceDictionary>

  <ResourceDictionary.MergedDictionaries>

    <ResourceDictionary Source="Dictionary1.xaml"/>

  </ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

this.Resources.MergedDictionaries.Add(Smyresourcedictionary);

简单地,转到MaindWindow.xaml您想要包含外部文件中的资源的窗口(例如:),并使用MergedDictionaries原则来引用该文件:

<Window x:Class="UseMergedResource.MainWindow"
        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"
        mc:Ignorable="d"
        Title="MainWindow"
        Height="600"
        Width="600">
  <Window.Resources>

    <!-- DECLARING MERGED DICTIONARY --> 
    <ResourceDictionary>
      <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source='Merged/BrushResources.xaml' />
      </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
    <!----------------------------------> 

  </Window.Resources>


  <StackPanel>
    <Rectangle Width='200'
               Height='100'
               Fill='{StaticResource PrimaryBrush}' /> <!-- USAGE HERE -->
  </StackPanel>
</Window>

从上面Merged/BrushResources.xaml是资源文件的位置,它位于名为Merged.

现在,如果您想知道外部文件中的声明语法应该是什么,请检查:

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

    <!-- Location for application brushes -->
    <SolidColorBrush x:Key='BorderBrush'
                                     Color='Orange' />
    <SolidColorBrush x:Key='HighLightBrush'
                                     Color='LightBlue' />
    <SolidColorBrush x:Key='PrimaryBrush'
                                     Color='Pink' />
    <SolidColorBrush x:Key='AccentBrush'
                                     Color='Yellow' />

</ResourceDictionary>

如果您想通过所有应用程序(在所有窗口中可见)使资源可用,请在App.xaml资源部分中声明。
