int arrays between C# and C++

[Guest]

How can I transport int arrays between C# and C++ so that an int array
created in C# will be filled with contents in the C++ dll and so that this
content is accessible in the C# dll again.

Using C++/CLI and accepting a parameter of type cli::array<int>^.

I am assuming by C++ you mean unmanaged C++ dll. Without the signature of
the C++ dll function, I cannot tell you a definitive answer but you can try
applying

[MArshalAs(UnmanagedType.ByValTArray,SizeConst=number of elements in array)]

attribute to your parameter/return type.
