Hi,

I have a method which returns an array of fixed type objects (let's say MyObject).

The method creates a new empty Stack<MyObject>. Then, it does some work and pushes some number of MyObjects to the end of the Stack. Finally, it returns the Stack.ToArray().

It does not change already added items or their properties, nor remove them. The number of elements to add will cost performance. There is no need to sort/order the elements.

Is Stack a best thing to use? Or must I switch to Collection or List to ensure better performance and/or lower memory cost?
