这个段代码只能添加贵宾不能添加学生
求解 --------------------编程问答-------------------- 看的人头晕，能不能简单点
--------------------编程问答-------------------- 可以debug，看添加学生的时候发生了什么 --------------------编程问答-------------------- 提出问题的时候，要指出你的具体问题的地方，或者加颜色，或者文字说明代码块。
这样提出的问题，回答率很很很很低的。 --------------------编程问答-------------------- case "入学套餐":
改为 case "入学体检":
--------------------编程问答-------------------- 建议：1。像这种在逻辑处理中需要用到的字符串最好永变量只保留一份拷贝，然后通过变量来引用。
2。写代码最好注意命名规范，不要懒，vs给你生成button1你就用button1. setA, setB也一点意义都没有。 --------------------编程问答-------------------- 只贴代码，我们除了要看代码之外还要猜猜你的问题是什么…… --------------------编程问答-------------------- 看的眼花缭乱的 测试一下
补充：.NET技术 , .NET Framework
