如何将Panel添加到SplitContainer？

using System;
using System.Windows.Forms;

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

            // 创建一个新的Panel控件
            Panel panel1 = new Panel();
            panel1.Dock = DockStyle.Fill;
            panel1.BackColor = Color.Red;

            // 将Panel添加到SplitContainer的面板1中
            splitContainer1.Panel1.Controls.Add(panel1);

            // 创建一个新的Panel控件
            Panel panel2 = new Panel();
            panel2.Dock = DockStyle.Fill;
            panel2.BackColor = Color.Blue;

            // 将Panel添加到SplitContainer的面板2中
            splitContainer1.Panel2.Controls.Add(panel2);

            // 设置SplitContainer的分隔条样式和位置
            splitContainer1.Orientation = Orientation.Horizontal;
            splitContainer1.SplitterDistance = 100;
        }
    }
}
