DataTable 递归 简单的程序，来实现无限级列表 结合 jquery.table.js 实现

 protected void DiGuiDataTable(DataTable FromDataTable, DataTable ToDataTable, object pid)

    {

        if (FromDataTable.Select("pid='" + pid + "'").Length > 0)

        {

            foreach (DataRow item in FromDataTable.Select("pid='" + pid + "'"))

            {

                ToDataTable.Rows.Add(item.ItemArray);

                DiGuiDataTable(FromDataTable, ToDataTable, item["id"]);

            }

        }

    }
