Stack Constructor (Int32)

Initializes a new instance of the Stack class that is empty and has the specified initial capacity or the default initial capacity, whichever is greater.

Namespace:  System.Collections
Assembly:  mscorlib (in mscorlib.dll)

new : 
        initialCapacity:int -> Stack

Parameters

initialCapacity
Type: System.Int32
The initial number of elements that the Stack can contain.

ExceptionCondition
ArgumentOutOfRangeException

initialCapacity is less than zero.

The capacity of a Stack is the number of elements that the Stack can hold. As elements are added to a Stack, 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.

This constructor is an O(n) operation, where n is initialCapacity.
