这是一个合适的MonoState Design吗？

Question

我有一个Person类，并基于我在这篇文章中收到的一些帮助。

MonoState, Singleton, or Derived Forms: Best approach for CRUD app?

我有一个CurrentPerson类周围（？），并予访问通的数据。

我想我明白这是应该如何工作，但似乎我没有相当没错。

问题：

1. 对于初学者来说，不应该Person和它的所有成员变量是私人？

2. 为什么Person在CurrentPerson中声明为静态？是对的吗？

3. Person实际上有子对象Address,Enrollment和CaseNote。我如何合并它们？ A CurrentEnrollment包装Enrollment？

我是相当新的OOP作为应用科学这样一些概念是我很难想象。

代码很长，我很抱歉。

附：如果丹尼尔布鲁克纳碰巧读到这个，请不要冒犯，因为我不是第二次猜测你的答案;我只需要深入澄清一些项目，以便正确理解在我的应用程序中使用monostate。

Answer 1

关于这些字段是否应该是私有的，这只是新的（C＃3.0？）声明属性而没有支持变量的方式。一个常见的变化是

public string SomeProperty { get; protected set } 

“课程，只要你想要做的事就像在二传手这不起作用验证，你必须回去写getter和setter方法，并声明后盾变量。

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

对于第三个问题，如果我理解你的权利，你愿意付出的Person类Address类型的属性和访问它是这样的：

Console.WriteLine(somePerson.HomeAddress.City);
