Variable argument list with Visual Basic? [duplicate]

问题

This question already has answers here:

Variable number of arguments in VB (3 answers)

Closed 5 years ago.

assumed I have a DLL that exports functions with variable arguments list like this:

int myfunc(int arg1,...)

Here "..." is a undefined number of additional arguments. Can such functions be called out of a Visual Basic application or is VB locked to functions with fixed arguments?

I'm just asking to avoid a design problem that would lock-out VB programmers...

Thanks!

回答1:

In VBA, functions can hand over an undefined number of arguments, so there should be no problem.

Directly in VBA, you'd define a function like this:

Function SumAll(ParamArray var() As Variant) As Double
    Dim i As Integer
    Dim tmp As Double
    For i = LBound(var) To UBound(var)
        If IsNumeric(var(i)) Then tmp = tmp + var(i)
    Next
    SumAll = tmp
End Function
