Stack Constructor (ICollection)
Initializes a new instance of the Stack class that contains elements copied from the specified collection and has the same initial capacity as the number of elements copied.
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 the number of elements in col.
