Urs,
In addition to the overload that Armin used.
Seeing as the parameter is an Optional array, consider using a ParamArray
instead:
Function Test(ByVal ParamArray a() As Integer) As Integer
End Function
Then when you call it, passing no parameters you will get an empty array.
Dim x As Integer
x = Test()
Passing a list of intergers you will get an array of integers.
x = Test(1,2,3,4,5)
Passing an array of integers you will get that array of integers.
Dim a() As Integer = {1,2,3,4,5}
x = Test(a)
Hope this helps

Hi!
This sounds probably quite silly, but I just can't figure out this one.
Consider the following which lets "a" be an array with 0 elements:
Dim a() As Integer
a = New Integer() {}
Now what do I have to code if I want an empty array as default value in
a function? This one doesn't work:
Function test(Optional ByVal a As Integer() = New Integer() {})
End Function
It says: Constant expression required. Is this not possible in general
because default values can only be simple types?
Greets and thanks,
Urs
