从对象内部的对象访问对象的参数

Question

我正在编写一个程序，其中我在另一个 class 中有一个 class。我需要知道我是否可以从内部访问外部 class 的属性。

像这样：

Module mod1

    Public Class c1
        Public var1 As Integer = 3

        Public Class c2

            Public Sub doSomething()
                'I need to access var1 from here. Is it possible?
            End Sub

        End Class

    End Class

End Module

非常感谢您的帮助！

编辑：我想做的事的例子

Dim obj1 As New c1 'Let's suppose that the object is properly initialized
Dim obj2 As New obj1.c2 'Let's suppose that the object is properly initialized

obj2.doSomething() 'Here, I want to affect ONLY the var1 of obj1. Would that be possible?

您仍然需要在这两个对象之间的某处创建一个 link。这是您如何操作的示例。

Dim obj1 As New c1
Dim obj2 As New c2(obj1)

obj2.doSomething()

doSomething 现在可以影响 c1 和 c2 中定义的两个变量。实施：

Public Class c1
    Public var1 As Integer = 3
End Class

Public Class c2
    Private linkedC1 As c1

    Public Sub New(ByVal linkedC1 As c1)
        Me.linkedC1 = linkedC1
    End Sub

    Public Sub doSomething()
        'I need to access var1 from here. Is it possible?
        linkedC1.var1 += 1
    End Sub

End Class
