If Count already equals the capacity, the capacity of the list is doubled by automatically reallocating the internal array before the new element is inserted.
If index is equal to Count, value is added to the end of CollectionBase.
In collections of contiguous elements, such as lists, the elements that follow the insertion point move down to accommodate the new element. If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does not apply to collections where elements are conceptually grouped into buckets, such as a hash table.
This method is an O(n) operation, where n is Count.
Notes to Implementers:
This method calls OnValidate, OnInsert, and OnInsertComplete.
