希望大神帮忙补完且修改UpData() ShowData() DelData()这三个 --------------------编程问答-------------------- 作业应该自己做！“大神”不需要练习这些习题。 --------------------编程问答-------------------- 你问思路说明你思考，你直接求代码算个怎么回事? --------------------编程问答-------------------- 好吧！删除那里能说说你的见解吗？ --------------------编程问答-------------------- 应该把
用private封装了，在用属性get，set获取，那个更加安全可靠
补充：.NET技术 , 非技术区
