Question

我在 VBA 中编写了一个函数，它将计算两个值。有什么方法可以让我从函数返回这两个值。

在 VBA 中，您可以通过两种方式返回更多值：返回数组或使用 ByRef 声明，请参见：

    'return as array
    Function ReturnTwoValues(x As Long) As Long()
        Dim ret(1) As Long
        ret(0) = x
        ret(1) = x * 2
        ReturnTwoValues = ret
    End Function

    'return parameters declared as ByRef
    Sub ReturnTwoPars(x As Long, ByRef y1 As Long, ByRef y2 As Long)
        y1 = x
        y2 = x * 2
    End Sub


    Sub Test()
        'return an array
        Dim ar() As Long
        ar = ReturnTwoValues(2) 'variable must be the same type as function
        Debug.Print ar(0), ar(1)

        'use ByRef
        Dim y1 As Long
        Dim y2 As Long
        ReturnTwoPars 2, y1, y2
        Debug.Print y1, y2

    End Sub
