Stack<T> Constructor (Int32)
Initializes a new instance of the Stack<T> class that is empty and has the specified initial capacity or the default initial capacity, whichever is greater.
Assembly: System (in System.dll)
The capacity of a Stack<T> is the number of elements that the Stack<T> can hold. As elements are added to a Stack<T>, the capacity is automatically increased as required by reallocating the internal array.
If the size of the collection can be estimated, specifying the initial capacity eliminates the need to perform a number of resizing operations while adding elements to the Stack<T>.
The capacity can be decreased by calling TrimExcess.
This constructor is an O(n) operation, where n is capacity.
