namespace WindowsApplication3
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        Label[,] label = new Label[256, 256];
        public void InitSeats(int seatRow, int seatLine, TabPage tb)
        {
            for (int i = 0; i < seatRow; i++)
            {
                for (int j = 0; j < seatLine; j++)
                {
                    label[i, j] = new Label();
                    label[i, j].BackColor = Color.Yellow;
                    label[i, j].AutoSize = false;
                    label[i, j].Font = new System.Drawing.Font("宋体", 14.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));
                    label[i, j].Location = new System.Drawing.Point(59, 60);
                    label[i, j].Name = "lbl" + (j + 1).ToString() + "_" + (i + 1).ToString();
                    label[i, j].Size = new System.Drawing.Size(50, 25);
                    //设置座位号
                    label[i, j].Text = (j + 1).ToString() + "-" + (i + 1).ToString();
                    label[i, j].TextAlign = ContentAlignment.MiddleCenter;
                    label[i, j].Location = new Point(60 + (i * 90), 60 + (j * 60));
                    tb.Controls.Add(label[i, j]);
                }
            }
        }
        private void button1_Click(object sender, EventArgs e)
        {
            InitSeats(2, 2, tabPage1);
            label[1,2]=new Label();
            label[1,2].BackColor=Color.Red;
        }
    }
}
在代码最后，我想让label[1,2].BackColor=Color.Red的，可以我的做法不对呀，根本就不变色，还是黄色，请高手指点，谢谢！

Answer 1

 label[1,2]=new Label();这句话去掉看看。 实在不行就遍历Controls内所有的label 把你想要的那个更改颜色
