新建資源文件

1

寫資源文件

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

引用資源

在獨立的窗口/用戶控件中引用

<Window x:Class="WpfDemo.Style.UseResourceDictionaryDemo"
        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"
        xmlns:local="clr-namespace:WpfDemo.Style"
        mc:Ignorable="d"
        Title="UseResourceDictionaryDemo" Height="300" Width="300">
    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="MyStyle.xaml"></ResourceDictionary>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
    <Grid>
        <Button Style="{StaticResource MyStyleButton}"></Button>
    </Grid>
</Window>

在App.xaml中統(tǒng)一引用(全局引用)

<!--App.xaml（WPF原生默認style.xaml姨丈，不同框架有所不同）-->
<Application x:Class="MAS.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Style/MyStyle.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

小結

寫法和寫在Resources中一樣，只是多了個ResourceDictionary的文件夷蚊，并需要引用ResourceDictionary文件才能使用Style

示例代碼

https://github.com/zLulus/NotePractice/tree/dev3/WPF/WpfDemo/Style 下的MyStyle和UseResourceDictionaryDemo
