C＃自定义类收集混淆
以下是我的自定义类，包含集合。我的应用程序是一个MDI应用程序，可以为多个程序多次打开“程序”表单，我希望使用ProgramBudget类，但是我希望程序预算内的所有“子类”都包含在程序表单ProgramBudget中类。C＃自定义类收集混淆
我有但是在子类中不断得到智能感知引用recursivelly问题（即：ProgramBudget.ParticipantTypeBudget.ParticipantTypeBudget.ParticipantTypeBudget ...）
什么是错的这个类，我如何使用它，自定义类低于：

ParticipantTypeBudget是ProgramBudget的成员。 ParticipantTypeBudget也继承了ProgramBudget，这意味着它获得了所有ProgramBudget的非私人成员。
看到问题了吗？
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();
摆脱这个递归，移动ParticipantTypeBudget，等出来的ProgramBudget。
编辑：另外，你问了汽车性能。那些属性没有明确的后台字段。我使用两种模式：
对于一个读/写性能，你这样做：
public int MyProperty {
get;
set;
}
注意，get和set不能有身体。
如果你需要一个只读属性，即一个只能由对象本身进行设置，使集合成员的保护：
public int MyProperty {
get;
protected set;
}
我为你添加了自动属性的例子。 – 2010-07-27 19:47:12
这就是所有的汽车属性？这很容易 – mattgcon 2010-07-27 20:04:45
是的。好，易于。请记住：如果你添加一个body来获取或设置，你必须实现另一个。 – 2010-07-27 20:16:37
由于ParticipantTypeBudget是ProgramBudget一个子类，它继承所有ProgramBudget的成员，包括所有嵌套类 - 因此，包括其本身。
然而，真正的问题是：为什么你要他们都是嵌套类？这会给你带来什么好处？
我怀疑OP没有自己编写所有的嵌套类 – 2010-07-27 19:31:52
Fyodor，我的意图是让所有的东西都包含在ProgramBudget对象中。我希望可以从表单中的ProgramBudget对象访问所有内容。这是甚至可能或正确的编码？ – mattgcon 2010-07-27 19:37:53
是的，我知道你希望他们都在ProgramBudger中。但问题是：你希望从这种安排中得到什么好处？ – 2010-07-27 19:46:52
您的派生类型是它们基类型的子类，因此创建了无限递归的父 - 子关系。将派生的子类移到它们自己的独立类中，以消除无限嵌套。
我很抱歉，大家浪费你的时间每一个人。我一直生病，而且当我创作这门课时，我并没有清楚地思考。我完全理解现在的复发事件，并且我应该为ProgramBudget类之外的每个子类创建自定义类，并为每个子类在ProgramBudget中创建一个属性。我将着眼于汽车性能并利用这一概念。
我们是否真的需要查看所有代码？毫无疑问？这就是为什么我低估了你的问题。 – 2010-07-27 19:28:27
有人需要了解自动属性！ – Aren 2010-07-27 19:28:44
认真 - 看看自动属性。它将为您节省大量的编码。 – 2010-07-27 19:30:22
