我正在尝试做一些非常简单的事情.我正在尝试创建一个窗口,其中有一个适合完美的圆圈.我制作了200x200的窗口和200x200的圆圈,它看起来像这样

这是我制作的代码:

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

class HalloForm : Form
{
    public HalloForm()
    {
        this.Text = "Hallo";
        this.BackColor = Color.LightGray;
        this.Size = new Size(200, 200);
        this.Paint += this.tekenScherm;
        this.AutoScaleMode = AutoScaleMode.Font;
    }

    void tekenScherm(object obj, PaintEventArgs pea)
    {

        tekenSmiley(pea, 0, 0, 200);
        /*pea.Graphics.DrawString("Hallo!"
                               , new Font("Tahoma", 30)
                               , Brushes.Blue
                               , 10, 10
                               );*/

        //pea.Graphics.DrawArc(Pens.Black, )

        //pea.Graphics.FillEllipse(Brushes.Black, new Rectangle(new Point(x + 40, y + 40), new Size(50, 50)));
        //pea.Graphics.FillEllipse(Brushes.Black, new Rectangle(new Point(x + 110, y + 40), new Size(50, 50)));
        //pea.Graphics.FillPolygon(Brushes.Black, …
