后台代码引用资源字典样式

1.资源字典定义：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">    <Style TargetType="Button" x:Key="GroupBoxButton">        <Setter Property="Width" Value="72"/>        <Setter Property="Height" Value="30"/>        <Setter Property="Margin" Value="5"/>        <Setter Property="Background" Value="Black"/>    </Style></ResourceDictionary>

2.后台代码

 Button b = new Button(); b.Style = FindResource("GroupBoxButton") as Style;
