------解决方案--------------------

C# code

ArrayList al = new ArrayList();
al.Add(1); // 将1加入数组
al.Add(3); // 将3加入数字
al.Insert(1, 2); // 在1和3直接插入一个元素
al.Remove(3); // 删除数组中的第一个3
al.Sort(); // 给数组排序
foreach (object o in al) { 
    // 遍历整个数组
}

------解决方案--------------------

还有点疑问如果我用结构体作为 arraylist 的元素以后页面控件的绑定是否还是和普通数组一样处理？
