WPF - 应用程序级别
在应用程序级别定义样式可以使其在整个应用程序中可访问。 让我们采用相同的示例，但在这里，我们将把样式放入 app.xaml 文件中，以便在整个应用程序中都可以访问它。 以下是 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>
以下是用于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>
