CollectionBase Constructor

Initializes a new instance of the CollectionBase class with the default initial capacity.

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

protected CollectionBase()

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

This constructor is an O(1) operation.
