    ＆LT; UserControl.Resources＆GT;
        ＆LT;风格的TargetType =TextBlock的＆GT;

    ＆LT; /UserControl.Resources>
    ＆LT;的TextBlock＆GT;您好！世界＆LT; / TextBlock的＆GT;

下面是它的外观：

解决方案

Silverlight不支持通过通用的样式隐含的造型（即用的TargetType，但没有一个静态的资源键 - X：键=），但WPF确实<。 / P>

您需要明确申请使用的StaticResource引用方式对你的元素，你想用风格的每个实例类型={的StaticResource的样式名的}。

借助 Silverlight工具包有一个隐含的样式管理器（ISM），获取解决这个从包装Silverlight的标记和应用样式ResourceDictionaries通过解析内容

Just playing around with Silverlight a bit and trying to set a style to apply to all TextBlocks. The following XAML:

<Style TargetType="{x:Type TextBlock}">
   <Setter Property="Margin" Value="10, 10, 10, 10" />
</Style>

Gives me the error Invalid attribute value {x:Type TextBlock} for property TargetType.

I copied and pasted this bit from the MSDN so I'm a little lost as to why I'm getting this error.

EDIT:

Here's the full code I'm attempting now:

<UserControl x:Class="NIRC.Page"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    Width="400" Height="300">
    <UserControl.Resources>
        <Style TargetType="TextBlock">
            <Setter Property="Margin" Value="10" />
            <Setter Property="Foreground" Value="Red" />
        </Style>
    </UserControl.Resources>
    <TextBlock>Hello World!</TextBlock>
</UserControl>

Here's how it looks:

解决方案

Silverlight does not support implicit styling via generic Styles (i.e. with a TargetType but without a static resource key - x:Key="") but WPF does.

You need to explicitly apply Styles using StaticResource references on each instance of your element that you want styled using Style="{StaticResource stylename}".

The Silverlight toolkit has an Implicit Style Manager (ISM) that gets around this by wrapping Silverlight markup and applying styles from ResourceDictionaries by parsing the content.
