帮我用c#写一个绘制爱心的程序

好的，以下是用 C# 绘制爱心的程序：

using System;
using System.Drawing;
using System.Windows.Forms;

namespace DrawHeart
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            // 设置画笔颜色和粗细
            Pen pen = new Pen(Color.Red, 3);

            // 绘制左半边的心形
            Point[] leftPoints = new Point[7];
            leftPoints[0] = new Point(50, 110);
            leftPoints[1] = new Point(30, 90);
            leftPoints[2] = new Point(20, 70);
            leftPoints[3] = new Point(20, 50);
            leftPoints[4] = new Point(30, 30);
            leftPoints[5] = new Point(50, 10);
            leftPoints[6] = new Point(70, 30);
            e.Graphics.DrawCurve(pen, leftPoints);

            // 绘制右半边的心形
            Point[] rightPoints = new Point[7];
            rightPoints[0] = new Point(70, 30);
            rightPoints[1] = new Point(90, 50);
            rightPoints[2] = new Point(100, 70);
            rightPoints[3] = new Point(100, 90);
            rightPoints[4] = new Point(90, 110);
            rightPoints[5] = new Point(70, 130);
            rightPoints[6] = new Point(50, 110);
            e.Graphics.DrawCurve(pen, rightPoints);
        }
    }
}

在窗口的 `Paint` 事件中，我们使用 `DrawCurve` 方法来绘制左半边和右半边的心形。最后我们需要设置画笔的颜色和粗细，这里我们使用红色和粗细为 3。

运行程序，即可看到绘制出来的爱心图案。
