ArrayList Constructor (ICollection)

Initializes a new instance of the ArrayList class that contains elements copied from the specified collection and that has the same initial capacity as the number of elements copied.

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

'Declaration
Public Sub New ( _
	c As ICollection _
)

Parameters

c
Type: System.Collections.ICollection
The ICollection whose elements are copied to the new list.

ExceptionCondition
ArgumentNullException

c is Nothing.

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

The elements are copied onto the ArrayList in the same order they are read by the IEnumerator of the ICollection.

This constructor is an O(n) operation, where n is the number of elements in c.
