Passing containers between C# and C++

[Kenneth Porter]

How do I pass a container from C# to C++?

My client is writing an app in C# that needs to pass a collection of 3-
space vectors to my native C++ library. It will also need to read back the
collection.

In pure native C++, I'd just pass a "std::vector<MyType>&" where MyType is
an x/y/z vector (which might contain a std::vector<double>).

What's the portable C++/CLI equivalent that C# can easily deal with?

The passed container might hold from 10,000 to 100,000 objects.

I might misunderstand your requirement, but you could always use
List<List<int>^or something (List from System::Collections::Generic).

Thanks, that sounds like the right thing.
