I'm a newbie to marshalling, what's the best way to call the following C++
function
from C#?

void foo(const vector<string> name) ?

I've tried doing a

[DllImport("test.dll"), CharSet = CharSet.Ansi)]
public static extern void foo(ArrayList name);

but that didn't work.

Hi,

I don't think there's an easy way to marshal STL template classes. I see
people are having problems even with regular string arrays. You can probably
set out to write a custom marshaler, but it's a LOT of pain IMO. I'd stick
to regular string arrays when doing C++ <-> C# interop.
