Declaring a parameter as a REF or OUT ARRAY

Good afternoon,

I am creating an interface in C++ using the managed extensions. I need to
declare a parameter as an out string[] (as would be represented in C#). Does
anyone know how to do this? Declaring out parameters generally takes the
form:

[Out] <type> __gc* name

and arrays generally take the form:

<type> name __gc[];

However, none of the below work:

[Out] <type> name __gc[] __gc*;
[Out] <type> name __gc* __gc[];
[Out] <type> __gc* name __gc[];

Any ideas?

What you want should probably be:
[Out] String * (&name) __gc[]

(ugly, yes, I know)

Hi Michael,

Thanks for posting in the community.

From your description, I understand that you want to declare a parameter
as an out string[] in an interface using the managed extensions.

Does Tomas's answer resolve your problem, if you still have questions or
concerns, please feel free to post it in the group.
Thanks!

Sorry if this is the wrong group. I tried to find the one I thought would be most relevant. I'm an old PHP guy, who knows little about asp and NOTHING about asp.net, but need to learn at least enough to convert a favorite PHP script to work on an ASP.NET site. I'm experimenting with simple example scripts that will help me learn how to implement each "piece" of the puzzle.

Hello, I'm having some difficulty compiling template classes as containers for other template objects. Specifically, I have a hierarchy of template classes that contain each other. Template class B has an instance of template class A, which has some base type T (usually int or double). However, the base type T is important to calculations in B, so I would like to obtain access to the type for further variable declaration within B. ...
