2、文件中内容显示出来。（提示：异常处理时要自定义异常，具体方法见参考程序） 2. A.封装一个学生类对象，将以上程序学生信息采用序列化方式写入二进制文件，并可输入学号随机查找相应记录信息显示在文本框中,查找记录时，也要求用异常处理处理输入学号为空的情况。 设计环境Pc机Visual studio2005设计步骤1. 编写程序2. 运行程序3. 得出实验结果设计程序1.using System;using System.Collections.Generic;using System.Linq;using System.Windows.Forms;namespace StudentLast sta
