格式显示

代码示例:

<Window
    xmlns:sys="clr-namespace:System;assembly=mscorlib"
    ...>
    <Window.Resources>
        <sys:String x:Key="k1">1000</sys:String>
        <sys:String x:Key="k2">2000</sys:String>
    </Window.Resources>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="30" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <TextBlock Grid.Row="0" Text="{StaticResource k1}" />
        <TextBlock Grid.Row="1">
            <TextBlock.Text>
                <MultiBinding StringFormat="{}{0} -- {1}">
                    <Binding Source="{StaticResource k1}" />
                    <Binding Source="{StaticResource k2}" />
                </MultiBinding>
            </TextBlock.Text>
        </TextBlock>
        <TextBlock Grid.Row="2">
            <Run Text="{StaticResource k1}" />
            <Run Text="--" />
            <Run Text="{StaticResource k2}" />
        </TextBlock>
        <TextBlock Grid.Row="3" Text="{Binding Source={StaticResource k1}, StringFormat={}{0} -- 123}" />
        <Label Grid.Row="5" Content="{Binding Source={StaticResource k2}, StringFormat={}{0}}" />
        <Label Grid.Row="6" Content="{Binding Source={StaticResource k2}, StringFormat={}{0}---321}" />
        <Label
            Grid.Row="7"
            Content="{Binding Source={StaticResource k2}}"
            ContentStringFormat="{}{0}---321" />
    </Grid>
</Window>
