What's the C# equivalent of C++ vector?

I am searching for this feature:

To have a dynamic array of contiguously stored memory that has no performance penalty for access vs. standard arrays.

I was searching and they say .NET equivalent to the vector in C++ is the ArrayList, so:

Do ArrayList have that contiguous memory feature?

You could use a List<T> and when T is a value type it will be allocated in contiguous memory which would not be the case if T is a reference type.

Example:

List<int> integers = new List<int>();
integers.Add(1);
integers.Add(4);
integers.Add(7);

int someElement = integers[1];
