What is the most efficient way to convert a std::vector to a .NET List?

Answer 1

Consider turning into the vector directly into an array .. the below will work and be valid, until you resize the vector.

vector vec(10); int *array = &vec[0];

Then, you should be able to treat that (I think -- VS not on machine) as a passed array to populate your list.

You should also create your list with a size that you expect to need -- adding one by one will be slow.
