C#实现商品信息的显示异常处理

 

实验四：C#实现商品信息的显示异常处理

任务要求：

在进销存管理系统中，商品的库存信息有很多种类，比如商品型号、商品名称、商品库存量等。在面向对象编程中，这些商品的信息可以存储到属性中，然后当需要使用这些信息时，再从对应的属性中读取出来。这里要求定义库存商品结构，并输出库存商品的信息。

 整体框架：

实现步骤：

第一步：创建cstockInfo类，并设置如下变量：

 

 第二步：按照如下内容定义商品的13个属性。

 

 

 

 

 

 

 第三步：创建cstockInfo类构造函数，并对商品属性进行初始化

 

 第四步：创建显示商品信息函数

 第五步：Main函数中输出标题

 第六步：创建商品对象，从键盘输入商品编号、单位全称、商品型号、库存数量四个数据，并显示商品信息(自行补充)

 第九步：实现对商品输入内容的约束并进行异常处理。(自行补充)

1、库存数量：数字，区间范围：1-1000

2、商品规格：“字符”+“-”+“数字”组成。如：TYPE-3

第九步：实现对商品信息多次输入，并进行判断，输入“q”退出程序。(自行补充)
