#region 用FlowLayoutPanel来布局

FlowLayoutPanel flowPanel = new FlowLayoutPanel();

flowPanel.Dock = DockStyle.Fill;  // 填充父容器

flowPanel.FlowDirection = FlowDirection.LeftToRight;  // 从左到右排列?:ml-citation{ref="3,4" data="citationList"}

flowPanel.WrapContents = true;

panel1.Controls.Add(flowPanel);

panel1.BackColor = Color.Red;

if (ds.Tables.Count > 0)

    _dt = ds.Tables[0];

    int dtRows = _dt.Rows.Count;

    if (dtRows > 0)

    {

        for (int i = 0; i < dtRows; i++)

        {

            byte[] bytes = (byte[])_dt.Rows[i]["image"];

            PictureBox pic = new PictureBox();

            pic.Size = new Size(200, 200);

            using (MemoryStream ms = new MemoryStream(bytes))
