写作例外 [英] writing exceptions

问题描述

1. 如何做到这一点向全班添加新学生的方法?如果试图在班级中已经存在具有相同ID的学生，并且试图将学生添加到班级中，则应该抛出异常.

解决方案

您好timalamu，

那不是对异常的正确使用.如果两个名称相同，则您可能会使用一条消息告诉用户两个输入的名称相同.

异常仅表示字符外行为.请查看MSDN中的异常说明:AC#异常是对程序运行时出现的异常情况的一种响应，例如尝试除以零.

1. how do I do this "Add a method to the class which adds a new student? It should throw an exception if an attempt is made to add a student to the class if a student with the same ID already exists in the class".

解决方案

Hi timalamu,

That is not the proper use of exception. If both name is same you could probably use a message to saying the user that both entered name is same.

Exception says only the out of character behavior. Please look into the exception defimation from MSDN: A C# exception is a response to an exceptional circumstance that arises while a program is running, such as an attempt to divide by zero.
