listBox的操作问题

Question

if (lbYTJ.SelectedIndex != -1)
            {
                foreach (ListItem item in lbYTJ.Items)
                {
                    if (item.Selected)
                    {                        lbYTJ.Items.Remove(item);
                        if (item.Value.Length >10)
                        {
                            Tools.AjaxAlert(this.Page, "个人");
                        }
                        else
                        {
                            Tools.AjaxAlert(this.Page, "组");
                        }
                    }
                   
                }在foreach里用lbYTJ.Items.Remove(item)报错这个问题怎么处理呢？就是把选中的item删除掉

你可以换个角度想想，比如将不必要删除的数据保存下来，然后重新绑定到控件上面
