How do I get a changed value back from C#

[tony]

Hello!

Assume I have an C++.net function called loadPostNames see below.
loadPostNames( dialog->GetAllPostNames(index) );
This function loadPostNames have GetAllPostNames(index) as a parameter.
Function GetAllPostNames is a method in C#.

Now to my question this identifier index passed as a parameter to method
GetAllPostNames is changed in
C# I want to be able to get the new changed value back to the C++.Net
function..

I have tried several possibilitys but I get compile error.

How should I write?

If the C# method is changing the value of the 'index' argument and you
want to propagate the changed index value back to the caller, then the
C# method should be written to use a 'ref int index' parameter (assuming
the index is an integer). This should translate as an 'int& index'
parameter in C++/CLI.
