WPF 给控件设置渐变背景色

代码：

RadialGradientBrush rgbrush = new RadialGradientBrush();
rgbrush.RadiusX = 0.5;
rgbrush.RadiusY = 1;
rgbrush.GradientStops.Add(new GradientStop((Color)ColorConverter.ConvertFromString("#FF4682D6"), 0.45));
rgbrush.GradientStops.Add(new GradientStop((Color)ColorConverter.ConvertFromString("#FF3867CC"), 0.87));
Control.Background = rgbrush;

Xaml:

<Control.Background >
    <RadialGradientBrush RadiusY="1" RadiusX="0.5">
        <GradientStop Color="#FF4682D6" Offset="0.45"/>
        <GradientStop Color="#FF3867CC" Offset="0.869"/>
    </RadialGradientBrush>
</Control.Background >

效果如下图：
