c# - 绘制节点图形绘制 C#

Question

编辑：我如何激活滚动条并在滚动后保持我的绘图，如 Paint 应用程序。如您所见，我正在客户端矩形之外绘制一个半径为 25px 的圆，但我无法滚动。

using System.Windows.Forms;

namespace Nodes
{
    public partial class Form1 : Form
    {
        
        public Form1()
        {
            InitializeComponent();
            this.DoubleBuffered = true;
            this.AutoScroll = true;
        }

        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
            g.DrawEllipse(Pens.Black, new Rectangle(0,this.ClientRectangle.Bottom, 50,50));
        }


    }
}
