我有一个Person班级,并且基于我在这篇文章中收到的一些帮助。

MonoState、Singleton 或派生形式:CRUD 应用程序的最佳方法?

我有一CurrentPerson堂课(??)它,我通过它访问数据。

我想我理解这应该如何工作,但似乎我做得不太对。

问题:

  1. 对于初学者来说,Person它的所有成员变量不应该是私有的吗?

  2. 为什么Person在声明时是CurrentPerson静态的?是对的吗?

  3. Person实际上有子对象Address,EnrollmentCaseNote. 我如何合并它们?一个CurrentEnrollment包装Enrollment

作为一门应用科学,我对 OOP 相当陌生,因此其中一些概念对我来说很难想象。

代码很长,请见谅。

PS 如果 Daniel Brückner 碰巧读到了这篇文章,请不要冒犯,因为我不是在猜测你的答案;我只需要对某些项目进行更深入的说明,以便正确理解单态在我的应用程序中的使用。

关于字段是否应该是私有的,这只是在没有支持变量的情况下声明属性的新方法(C# 3.0?)。一个常见的变化是

public string SomeProperty { get; protected set }

'当然,一旦你想在 setter 中做类似验证的事情,这不起作用,你必须回去编写 setter 和 getter,并声明一个支持变量。

我不确定静态CurrentPerson.Person()方法的意图是什么,或者它是如何设置的。

对于第三个问题,如果我理解你的话,你会给Person类一个类型的属性Address并像这样访问它:

Console.WriteLine(somePerson.HomeAddress.City);
