在Visual Studio中使用Windows Forms和C#，有没有一种方法可以让Graphics.DrawEllipse函数完全按照指定的方式绘制椭圆？

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

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

        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;

            Pen pen = new Pen(Color.Black, 2);
            Rectangle rect = new Rectangle(50, 50, 200, 100);
            g.DrawEllipse(pen, rect);
        }
    }
}
