如何在wp7中以编程方式为具有特定样式的按钮设置背景？

Question

我想在按钮的代码中执行以下设置。

<Button.Background> 
    <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> 
    <GradientStop Color="DarkSlateGray" Offset="0" /> 
    <GradientStop Color="White" Offset="1" /> 
    </LinearGradientBrush> 
</Button.Background> 

有谁知道如何做到这一点？

大概是这样的：

var brush = new LinearGradientBrush {EndPoint = new Point(0.5, 1), StartPoint = new Point(0.5, 0)}; 
brush.GradientStops.Add(new GradientStop {Color = Color.FromArgb(0xFF, 0x2F, 0x4F, 0x4F), Offset = 0}); 
brush.GradientStops.Add(new GradientStop {Color = Color.FromArgb(0xFF, 0xFF, 0xFF, 0xFF), Offset = 1}); 
TheButton.Background = brush;
