How to pass an array as an optional argument

Question

Hi,

I would like to pass a multi-dimensional array as an optional argument to a procedure.  The trouble is I'm having difficulty trying to assign the array to a default value.  Can anyone help?!

You can't initialize a multi-dimensional array inline with the function/sub declaration as it needs to be a constant expression, instead try something like the following:

Public Sub MyMethod(Optional ByVal array(,) As Short = Nothing)     If (array Is Nothing) Then         array = New Short(1, 1) {{10, 10}, {10, 10}}     End If End Sub

Let's consider the following:

(ByVal A As String , Optional ByVal Filespec As String = Nothing)

It doesn't make any difference if you say...

(ByVal A As String , Optional ByVal B As system.array = Nothing)

:)
