public void painLabel()
        {
            Label[] lbl = new Label[5];
            for (int i = 0; i < 5; i++)
            {
                lbl[i]=new Label();
                lbl[i].Name = "lbl" + i.ToString();
                lbl[i].Text = "lbl" + i.ToString();
                this.Controls.Add(lbl[i]);
                lbl[i].Location = new Point(i,i*50);
            }
        }

这样也可以的 数组
