请教问题，在form1中动态创建了3000个label控件，name分别为lb[0]到lb[2999].现在创建timer控件来调用这些label控件，显示错误 “ 当前上下文中不存在名称“lb”   ”。这个问题该怎么解决呢？

能不能通过动态的设置这3000个label的modifiers属性来实现呢？

public Form1()
        {
            InitializeComponent();


        }

         public void Form1_Load(object sender, EventArgs e)
         {
         Label [] lb = new Label[3000];
　　
  for(int i = 0; i < 3000; i++)
 {
 lb[i] = new Label();
     
 lb[i].Location = new System.Drawing.Point( 80+12 * (i % 100),180+15 * (i / 100));
 lb[i].Name = "btnTest";
 lb[i].Size = new System.Drawing.Size(10, 12);
 lb[i].Text = ".";
   lb[i].BackColor = Color.White;
   lb[i].Modifiers=public;
   //lb[i].Font = new Font("微软雅黑", 30, FontStyle.Bold, GraphicsUnit.Pixel);
 this.Controls.Add(lb[i]);
         
 }
   
      }
 public  void timer1_Tick(object sender, EventArgs e)
{
           int Vmax;
          Vmax = int.Parse(textBox2.Text);
          int q=0;
          int m;
          int v=0;
          int j;
          for (j = 0; j < 100; j=j + v)
          {
              if (lb[j].Text != ".")
              {
                  v = int.Parse(lb[j].Text);
                  for (m = 1; m <= v; m++)
                  {
                      if (lb[j + m].Text == ".")
                      {
                          q = 1;
                      }
                      else
                      {
                          q = 0;
                          break;
                      }
                  }
                  if (q == 1 && v < Vmax)
                  {
                      v++;
                  }
                  else if (q == 0 && v > 0)
                  {
                      v--;
                  }
                  else v = v + 1 - 1;
              }
              lb[j + v].Text = v.ToString();
              lb[j].Text = ".";
}



在 void timer1_Tick里面调用lb[i]等 就显示上下文不存在“lb”  怎么解决呢？谢谢

十分感谢，我是c#初学者！
