如何在WPF中使用线条连接椭圆？

<Window x:Class="WpfApp1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="WPF Line and Ellipse" Height="450" Width="800">
    <Canvas x:Name="canvas">
        <!-- 椭圆 -->
        <Ellipse Width="100" Height="50" Fill="LightBlue" Canvas.Left="100" Canvas.Top="100" />
        <!-- 线条 -->
        <Line X1="150" Y1="125" X2="250" Y2="125" Stroke="Black" StrokeThickness="2" />
    </Canvas>
</Window>

using System.Windows;

namespace WpfApp1
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            // 设置线条和椭圆的位置
            Canvas.SetLeft(line, 150);
            Canvas.SetTop(line, 125);
            Canvas.SetLeft(ellipse, 100);
            Canvas.SetTop(ellipse, 100);
        }
    }
}
