Optional arguments

[Jens Thiel]

Hi all, I would like to exactly mimic the following VB.NET interface

Public Shared Function Fun( _
Optional ByVal p As Integer = 10 _
) As Double()

in C#. I already use OptionalAttribute from System.Runtime.InteropServices.
I tried to combine it with DefaultValueAttribute from System.ComponentModel
but the result is not the same. How do I set the default value in the same
way VB.NET does?

(I do not want to overload or discuss overloads ./. optional parameters ;-)

Oh well... I thought that this would be the answer. Thanks anyway!

Jens,

You can't, it's simply not supported in C#.
