class - 将对象传递给类方法: Object doesn't support this property or method

Question

您好，我正在使用 excel 2013 vba，我想将工作表对象传递给类函数:

'类模块Class1'

Sub receive(ByRef ws As Worksheet)
    msgbox ws.name
End Sub

调用类方法接收:

Sub passToClass()
  Dim ws as Worksheet
  Set ws = ThisWorkbook.Worksheets("sheet1")
  Dim myClass As New Class1
  myClass.receive(ws) ' Run-time Error '438': Object doesn't support this property or method
End Sub

一个有效的简单测试是同一模块中的两个子例程:

Sub pass()
   Dim ws as Worksheet
   Set ws = ThisWorkbook.Worksheets("sheet1")
   call receive(ws)
End Sub

Sub Receive(ByRef ws As Worksheet)
    msgbox ws.name
End Sub

我在概念上缺少什么？

提前致谢!

Answer 1

您需要从调用中删除括号:

myClass.receive ws

或添加Call关键字:

Call myClass.receive(ws)

只有在以下情况下调用例程时才需要括号:

• 您使用Call关键字；或
• 您正在调用函数并且使用返回值；或
• 您明确需要评估或取消引用您传递的变量。
