XAML - 应用程序级别

在应用程序级别定义样式可使其在整个应用程序中可访问。让我们看看同一个示例；只需将样式放在 app.xaml 文件中即可使其在整个应用程序中可访问。下面给出的是 app.xaml 中的 XAML 代码。

<Application x:Class = "Styles.App" 
   xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation"
   xmlns:x = "http://schemas.microsoft.com/winfx/2006/xaml"
   StartupUri = "MainWindow.xaml">
	
   <Application.Resources>
      <Style TargetType = "TextBlock">
         <Setter Property = "FontSize" Value = "24" />
         <Setter Property = "Margin" Value = "5" />
         <Setter Property = "FontWeight" Value = "Bold" />
      </Style>
		
      <Style TargetType = "TextBox">
         <Setter Property = "HorizontalAlignment" Value = "Left" />
         <Setter Property = "FontSize" Value = "24" />
         <Setter Property = "Margin" Value = "5" />
         <Setter Property = "Width" Value = "200" />
         <Setter Property = "Height" Value = "40" />
      </Style>
   </Application.Resources>
	
</Application>

以下是创建文本块和文本框的 XAML 代码。

<Window x:Class = "Styles.MainWindow" 
   xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation"
   xmlns:x = "http://schemas.microsoft.com/winfx/2006/xaml" 
   Title = "MainWindow" Height = "350" Width = "604">
	
   <Grid>
      <Grid.RowDefinitions>
         <RowDefinition Height = "Auto" />
         <RowDefinition Height = "Auto" />
         <RowDefinition Height = "Auto" />
         <RowDefinition Height = "*" />
      </Grid.RowDefinitions>
		
      <Grid.ColumnDefinitions>
         <ColumnDefinition Width = "*" />
         <ColumnDefinition Width = "2*" />
      </Grid.ColumnDefinitions>
		
      <TextBlock Text = "First Name: "/>
      <TextBox Name = "FirstName" Grid.Column = "1" />
      <TextBlock Text = "Last Name: " Grid.Row = "1" />
      <TextBox Name = "LastName" Grid.Column = "1" Grid.Row = "1" />
      <TextBlock Text = "Email: " Grid.Row = "2" />
      <TextBox Name = "Email" Grid.Column = "1" Grid.Row = "2"/>
   </Grid>
	
</Window>

当上述代码被编译并执行时，它将产生以下输出。观察输出是否保持不变。
