vb6里面如何实现类似VB.net的clone实例?

segray

'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.

segray

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~
