ArrayList.AddRange Method (ICollection)


Adds the elements of an ICollection to the end of the ArrayList.

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

abstract AddRange : 
        c:ICollection -> unit
override AddRange : 
        c:ICollection -> unit


Type: System.Collections.ICollection

The ICollection whose elements should be added to the end of the ArrayList. The collection itself cannot be null, but it can contain elements that are null.

Exception Condition

c is null.


The ArrayList is read-only.


The ArrayList has a fixed size.

ArrayList accepts null as a valid value and allows duplicate elements.

The order of the elements in the ICollection is preserved in the ArrayList.

If the new Count (the current Count plus the size of the collection) will be greater than Capacity, the capacity of the ArrayList is increased by automatically reallocating the internal array to accommodate the new elements, and the existing elements are copied to the new array before the new elements are added.

If the ArrayList can accommodate the new elements without increasing the Capacity, this method is an O(n) operation, where n is the number of elements to be added. If the capacity needs to be increased to accommodate the new elements, this method becomes an O(n + m) operation, where n is the number of elements to be added and m is Count.

The following code example shows how to add elements to the ArrayList.
