答案简单:

1)大多数.
2)因为没有它，我们就无法覆盖方法.
3)可以提供工作方法和属性.
4)就个人而言，具有非常长且复杂的函数名称...

而且我的确意识到，除非您已经理解了这些答案，否则这些答案对您并没有太大帮助，并且任何面试官都希望您说出更多的内容.

我们不能通过面试让你.除非您戴着假胡须并以不同的名字申请同一份工作，否则这四个问题不太可能再次面试.如果您自己不知道这些问题的答案，那么您需要返回C#的基础知识并学习它如何正常工作-因为下一次问题将在OOPS概念的非常不同的部分出现.

抱歉，但这就是世界运作的方式.

The answers in brief:

1) Most of them.
2) Because without it we can''t override methods.
3) Can can provide working methods and properties.
4) Personally, with very long and complex function names...

And I do realize that these answers aren''t a lot of help to you, unless you already understand the answers, and that any interviewer is going to want you to say a heck of a lot more than this.

We can''t get you though an interview. These four questions are very unlikely to come up in an interview again, unless you wear a false moustache and apply for the same job under a different name. If you do not know the answers to these questions yourself, then you need to go back to the basics of C# and learn how it works properly - because next time the questions will be on very different parts of the OOPS concept.

Sorry, but that is the way the world works.
