示例
1、样式(App.xaml)

<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
             x:Class="Silverlight20.App"
             >
    <Application.Resources>
    
        <!--全局样式 - 任何地方都可引用-->
        <!--
        Style - 自定义样式资源。用于修改控件的样式。各个控件的默认样式可参见文档
            x:Key - 唯一标识
            TargetType - 目标对象类型
            Setter - 属性设置器
                Property - 需要设置的属性名称
                Value - 需要设置的属性值
        -->

            <Setter Property="Foreground" Value="#0000FF"/>
        </Style>

    </Application.Resources>
</Application>

样式(Style.xaml)
