示例代码示例:
Option Explicit
Dim obj: Set obj = New Foo
WScript.Echo "EnvFlags(0)=" & obj.EnvFlags(0) 'EnvFlags(0)=False
WScript.Echo Join(obj.EnvFlags(-1), ",") 'False,False,False
On Error Resume Next 'enabled just for facility's sake
obj.EnvFlags 0, True '<< Why this NOT work?...
If Err Then WScript.Echo Err.Number, Err.Description
'> 450 Wrong number of arguments or invalid property assignment
On Error Goto 0
Class Foo
Private mEnvFlags
Public Property Let EnvFlags(nIndex, bValue)
If vbBoolean <> VarType(bValue) Then Exit Property
If nIndex >= 0 And nIndex <= 2 Then
mEnvFlags(nIndex) = bValue
End If
End Property
Public Property Get EnvFlags(nIndex)
If nIndex < 0 Or nIndex > 2 Then
EnvFlags = mEnvFlags
Else
EnvFlags = mEnvFlags(nIndex)
End If
End Property
Private Sub Class_Initialize
mEnvFlags = Array(False, False, False)
End Sub
End Class
如何解决? (还有奖金-为什么会发生?)谢谢 最佳答案
请引用 Property Let
的文档。 Property Let
与子例程调用不同。正确的语法是
obj.EnvFlags(0) = True
