如何在wp7中以編程方式為具有特定樣式的按鈕設置背景？

Question

我想在按鈕的代碼中進行以下設置。

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

有誰知道如何做到這一點？

Answer 1

大概是這樣的：

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;
