Declaring a parameter as a REF or OUT ARRAY

[Michael Gunter]

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?

Michael,

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

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!
