我试图填补我的两个半圆。我想要一面黑色，另一面白色。我用什么？

这是我的代码片段：

    protected override void OnPaint(PaintEventArgs e)
    {
        base.OnPaint(e);
        Rectangle rect = new Rectangle(100, 100, 320, 320);
        e.Graphics.DrawArc(new Pen(new SolidBrush(Color.Black), 10), rect, 90, 180);
        e.Graphics.DrawArc(new Pen(new SolidBrush(Color.White), 10), rect, 270, 180);
    }

我想在C#windows Form Application上绘制YinYang符号.到目前为止,我画了一个大的外圈和两个内在的圈子.

我需要帮助绘制沿圆圈中间延伸的曲线部分

另外,我如何填充小圆圈和圆圈的另一半为黑色.

此外,无需使用按钮即可绘制(请参阅代码).

这是我的代码片段:

    private void button1_Click(object sender, EventArgs e)
    {
        Graphics myGraphics = base.CreateGraphics();
        Pen myPen = new Pen(Color.Black);
        SolidBrush mySolidBrush = new SolidBrush(Color.Black);
        myGraphics.DrawEllipse(myPen, 50,50, 150, 150);

        Graphics innerCircle = base.CreateGraphics();
        Pen myPen2 = new Pen(Color.Black);
        SolidBrush mySolidBrush2 = new SolidBrush(Color.Black);
        myGraphics.DrawEllipse(myPen, 118, 75, 20, 20);

        Graphics innerCircle2 = base.CreateGraphics();
        Pen myPen3 = new Pen(Color.Black);
        SolidBrush mySolidBrush3 = new SolidBrush(Color.Black);
        myGraphics.DrawEllipse(myPen, 118, 150, 20, 20);
    }
