一步一步学Silverlight ：基本图形

Rectangle

Rectangle看名称就知道是矩形，设置长度和高度相等则为正方形，其主要的属性还是开始我们提到的那三个，同时还可以通过RadiusX和RadiusY来设置它的圆角效果，看下面的例子：

<Canvas Background="#CDFCAE">
    <Rectangle Canvas.Top="20" Canvas.Left="40"
         Width="160" Height="80" Fill="#FF9900"
         Stroke="Black" StrokeThickness="3">
    </Rectangle>

    <Rectangle Canvas.Top="20" Canvas.Left="260"
         Width="180" Height="100">
        <Rectangle.Fill>
            <RadialGradientBrush GradientOrigin="0.5,0.5" Center="0.5,0.5"
            RadiusX="0.5" RadiusY="0.5">
                <GradientStop Color="#0099FF" Offset="0" />
                <GradientStop Color="#FF0000" Offset="0.25" />
                <GradientStop Color="#FCF903" Offset="0.75" />
                <GradientStop Color="#3E9B01" Offset="1" />
            </RadialGradientBrush>
        </Rectangle.Fill>
    </Rectangle>

    <Rectangle Canvas.Top="120" Canvas.Left="120"
         Width="100" Height="100"
         Stroke="#000000" StrokeThickness="2" RadiusX="15" RadiusY="15">
        <Rectangle.Fill>
            <LinearGradientBrush StartPoint="0,1">
                <GradientStop Color="#FFFFFF" Offset="0.0" />
                <GradientStop Color="#FF9900" Offset="1.0" />
            </LinearGradientBrush>
        </Rectangle.Fill>
    </Rectangle>
</Canvas>

运行后如下所示，其中有两个加上了渐变效果：
