如何将面板添加到另一个面板

Question

当我单击button1时，我想将 面板之一，……添加到panel0中。

这是我的代码

private void button3_Click(object sender, EventArgs e)
        {
            int i = 0;
            int j = 0;


            Panel[] pnl = new Panel[3];

            while ( i<2)
            {
                pnl[i].Parent = panel0;                  // erorr

                pnl[i].BackColor = Color.PeachPuff;

                pnl[i].Size = new Size(50, 10);
                pnl[i].Location = new Point(j+5,10);
                panel0.Controls.Add(pnl[i]);
                pnl[i].BringToFront();

                i++;
                j = j + 13;
            }
         }

有建议吗？

将Panel [] pnl =新Panel [3]更改为：

var pnl  = new List<Panel>{existingPanel1, existingPanel2, existingPanel3};
