vb6里面如何实现类似VB.net的clone实例?

[超级大笨狼]

'local variable(s) to hold property value(s)
Private mvarA As String 'local copy


Public Property Let A(ByVal vData As String)
'used when assigning a value to the property, on the left side of an assignment.
'Syntax: X.A = 5
mvarA = vData
End Property


Public Property Get A() As String
'used when retrieving value of a property, on the right side of an assignment.
'Syntax: Debug.Print X.A
A = mvarA
End Property

byval不起作用,vb6里面如何实现VB.net的clone实例?

很久没做过VB了,回头看觉得很不爽.

[超级大笨狼]

Private Sub Form_Load()
Dim testA, testB, testC
Set testA = New Class1
''MsgBox testA.Property(0)
''MsgBox CStr(testA.Class)
testA.A = "A"

Set testB = testA
testB.A = "B"
MsgBox testA.A

Set testC = clone(testA)
testC.A = "C"
MsgBox testA.A
'' testA.a=
End Sub

Private Function clone(ByVal instance) As Class1
Set clone = New Class1
Set clone = instance
End Function

只能自己写深度拷贝的代码,即,一个一个属性写过去

逐个赋值~
