Is std.container.array more or less an equivalent of C#'s List<T>?

[A Guy With a Question]

Reading this, the interface seems very similar, but I'm not sure. 
There's only like a two sentence general description, then it 
goes on to talk about a boolean specialization...

I'm looking for something that doesn't have to resize every 
insert/append, but also it's going to be copying the whole array 
either each time.
