這是一個合適的MonoState Design嗎？

Question

我有一個Person類，並基於我在這篇文章中收到的一些幫助。

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

我有一個CurrentPerson類周圍（？），並予訪問通的數據。

我想我明白這是應該如何工作，但似乎我沒有相當沒錯。

問題：

1. 對於初學者來說，不應該Person和它的所有成員變量是私人？

2. 爲什麼Person在CurrentPerson中聲明爲靜態？是對的嗎？

3. Person實際上有子對象Address,Enrollment和CaseNote。我如何合併它們？ A CurrentEnrollment包裝Enrollment？

我是相當新的OOP作爲應用科學這樣一些概念是我很難想象。

代碼很長，我很抱歉。

附：如果丹尼爾布魯克納碰巧讀到這個，請不要冒犯，因爲我不是第二次猜測你的答案;我只需要深入澄清一些項目，以便正確理解在我的應用程序中使用monostate。

Answer 1

關於這些字段是否應該是私有的，這只是新的（C＃3.0？）聲明屬性而沒有支持變量的方式。一個常見的變化是

public string SomeProperty { get; protected set } 

「課程，只要你想要做的事就像在二傳手這不起作用驗證，你必須回去寫getter和setter方法，並聲明後盾變量。

我不確定靜態CurrentPerson.Person()方法的目的是什麼，或者它是如何設置的。

對於第三個問題，如果我理解你的權利，你願意付出的Person類Address類型的屬性和訪問它是這樣的：

Console.WriteLine(somePerson.HomeAddress.City);
