Question

我编写了一个程序，我在另一个类中有一个类。我需要知道我是否可以从内部类访问外部类的属性。

这样的事情：

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?

您仍然需要在某处创建这两个对象之间的链接。这是一个如何做到这一点的例子。

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

obj2.doSomething()

doSomething 现在可以影响 c1 和 c2 中定义的变量。实现：

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

从对象内部的对象访问对象的参数
