将c#中数组中的标签置于最前面

我创建了一组标签，试图在一个有游戏板图片的图片框上显示。我一直在图片框后面显示标签，不确定自己做错了什么。

public Form1()
    {
        InitializeComponent();
        int x = 100;
        int y = 0;
        // create 361 labels, set their dimensions
        for (int i = 0; i < 361; i++)
        {
            board[i] = new Label();
            board[i].Parent = pictureBox1;
            board[i].Location = new Point(x, y);
            board[i].Name = "label" + i;
            board[i].Width = 55;
            board[i].Height = 55;
            board[i].Text = "0";
            board[i].BackColor = Color.Black;
            board[i].BringToFront();
        }

        // set the position of the label
        foreach (Label i in board)
        {
            if (x >= 580)
            {
                x = 0;
                y = y + i.Height + 55;
            }
            i.Location = new Point(x, y);
            this.Controls.Add(i);
            x += i.Width;
        }

// set the position of the label
foreach (Label i in board)
{
    if (x >= 580)
    {
        x = 0;
        y = y + i.Height + 55;
    }
    i.Location = new Point(x, y);
    this.Controls.Add(i);
    i.BringToFront();
    x += i.Width;
}
