C＃自定義類收集混淆

以下是我的自定義類，包含集合。我的應用程序是一個MDI應用程序，可以爲多個程序多次打開「程序」表單，我希望使用ProgramBudget類，但是我希望程序預算內的所有「子類」都包含在程序表單ProgramBudget中類。C＃自定義類收集混淆

我有但是在子類中不斷得到智能感知引用recursivelly問題（即：ProgramBudget.ParticipantTypeBudget.ParticipantTypeBudget.ParticipantTypeBudget ...）

什麼是錯的這個類，我如何使用它，自定義類低於：

我們是否真的需要查看所有代碼？毫無疑問？這就是爲什麼我低估了你的問題。 – 2010-07-27 19:28:27

有人需要了解自動屬性！ – Aren 2010-07-27 19:28:44

認真 - 看看自動屬性。它將爲您節省大量的編碼。 – 2010-07-27 19:30:22

ParticipantTypeBudget是ProgramBudget的成員。 ParticipantTypeBudget也繼承了ProgramBudget，這意味着它獲得了所有ProgramBudget的非私人成員。

看到問題了嗎？

class Foo { 
    class Bar : Foo { 

    } 
} 

//perfectly legal: 
Foo.Bar.Bar.Bar.Bar.Bar = new Foo.Bar.Bar.Bar.Bar.Bar.Bar.Bar.Bar.Bar.Bar.Bar.Bar();

擺脫這個遞歸，移動ParticipantTypeBudget，等出來的ProgramBudget。

編輯：另外，你問了汽車性能。那些屬性沒有明確的後臺字段。我使用兩種模式：

對於一個讀/寫性能，你這樣做：

public int MyProperty { 
    get; 
    set; 
}

注意，get和set不能有身體。

如果你需要一個只讀屬性，即一個只能由對象本身進行設置，使集合成員的保護：

public int MyProperty { 
    get; 
    protected set; 
}

我爲你添加了自動屬性的例子。 – 2010-07-27 19:47:12

這就是所有的汽車屬性？這很容易 – mattgcon 2010-07-27 20:04:45

是的。好，易於。請記住：如果你添加一個body來獲取或設置，你必須實現另一個。 – 2010-07-27 20:16:37

由於ParticipantTypeBudget是ProgramBudget一個子類，它繼承所有ProgramBudget的成員，包括所有嵌套類 - 因此，包括其本身。

然而，真正的問題是：爲什麼你要他們都是嵌套類？這會給你帶來什麼好處？

2010-07-27 19:28:29

我懷疑OP沒有自己編寫所有的嵌套類 – 2010-07-27 19:31:52

Fyodor，我的意圖是讓所有的東西都包含在ProgramBudget對象中。我希望可以從表單中的ProgramBudget對象訪問所有內容。這是甚至可能或正確的編碼？ – mattgcon 2010-07-27 19:37:53

是的，我知道你希望他們都在ProgramBudger中。但問題是：你希望從這種安排中得到什麼好處？ – 2010-07-27 19:46:52

您的派生類型是它們基類型的子類，因此創建了無限遞歸的父 - 子關係。將派生的子類移到它們自己的獨立類中，以消除無限嵌套。

我很抱歉，大家浪費你的時間每一個人。我一直生病，而且當我創作這門課時，我並沒有清楚地思考。我完全理解現在的復發事件，並且我應該爲ProgramBudget類之外的每個子類創建自定義類，併爲每個子類在ProgramBudget中創建一個屬性。我將着眼於汽車性能並利用這一概念。
