小弟剛接觸C#所以有滿滿的問題......
目前打算在forms裡建一個陣列讓其他usercontrol在執行時可以存值在裡面，但在寫usercontrol程式碼時都會說找不到這個陣列，請問各位C#高手是發生什麼問題QQ
是陣列沒有Public嗎??

forms1

using System;
using System.Windows.Forms;
using System.Collections.Generic;

namespace WindowsFormsApp1
{
    public partial class Form1 : Form
    {

        public Form1()
        {
            InitializeComponent();
        }
        
        string[] orderlist = new string[5];
        
        private void button1_Click(object sender, EventArgs e)
        {
            SidePanel.Height = button1.Height;
            SidePanel.Top = button1.Top;
            panel2.Controls.Clear();
            panel2.Controls.Add(new UserControl1());
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            panel2.Controls.Add(new UserControl1());
            SidePanel.Height = button1.Height;
            SidePanel.Top = button1.Top;
        }
    }
}

usercontrol

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApp1
{
    public partial class UserControl1 : UserControl
    {
        public UserControl1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {

            orderlist[0] = "漢堡";
            this.Controls.Clear();
            this.Controls.Add(new UserControl6());
        }
    }
}
