I'm converting a .NET gateway interface (call .NET code from IRIS) from the old "Caché style" that use imported proxy class to the new $system.external .NET gateway as documented in:
https://docs.intersystems.com/iris20221/csp/docbook/DocBook.UI.Page.cls…
For simple case it works and I'm fine, unfortunately I don't understand how to implement/access .NET arrays from IRIS and unfortunately the documentation has no info whatsoever on how to work with arrays.
What I'm looking for is how to implement the same code as described in the old .NET gateway
