稳扎稳打Silverlight(7) - 2.0图形之Ellipse, Line, Path, Polygon, Polyline, Rectangle

作者：webabcd


介绍
Silverlight 2.0 图形：
    Ellipse - 椭圆
    Line - 线
    Path - 一系列相互连接的直线和曲线
    Polygon - 多边形，闭合图形，起点与终点自动相连
    Polyline - 非闭合图形，一串连接起来的线，起点与终点不会自动相连
    Rectangle - 矩形

示例
1、Ellipse.xaml

<UserControl x:Class="Silverlight20.Shape.Ellipse"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <StackPanel HorizontalAlignment="Left">
        
        <!--椭圆-->
        <!--
        Width - 椭圆的宽
        Height - 椭圆的高
        Stroke - 边框
        StrokeThickness - 边框尺寸
        Fill - 填充
        -->
        <Ellipse Stroke="Red" Fill="Yellow" StrokeThickness="6" Width="100" Height="50"></Ellipse>
        
    </StackPanel>
</UserControl>

2、Line.xaml

<UserControl x:Class="Silverlight20.Shape.Line"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    <StackPanel HorizontalAlignment="Left">
        
        <!--线-->
        <!--
        X1 - 起点的 X 坐标
        Y1 - 起点的 Y 坐标
        X2 - 终点的 X 坐标
        Y2 - 终点的 Y 坐标
        注：
            Line无填充，也就是Line的Fill属性无效
            坐标以左上角为原点，原点右侧/下侧为正方向
        -->
        <Line X1="0" Y1="100" X2="200" Y2="300" Stroke="Black" StrokeThickness="6" />
