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.
Assembly: mscorlib (in mscorlib.dll)
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.
