是否可以确定访问对象的对象是什么？

Question

假设我有这些课程

Public Class Connection
    Private a as Node
    Private b as Node

    Public Property Self as Node
    Public Property Other as Node

    Public Sub New(a as Node, b as Node) 
        Me.a = a : Me.b = b
        a.Connection = Me : b.Connection = Me
    End Sub
End Class

Public Class Node 
    Public Connection as Connection
End Class

我就这样设置了

Dim a = New Node()
Dim b = New Node()
Dim c = New Connection(a, b);

因此两个节点共享同一个Connection对象。现在我想弄清楚是否有可能为Connection属性Self和Other定义一个getter，它可以检测到他们正在访问哪个对象并相应地改变它们的返回值？

例如一些伪代码

Public Property Other as Node
Get
    If (<CalledThroughObject> = a) Then Return b
    Return a
End Get

这应该是结果

a.Connection.Other = b
b.Connection.Other = a
