System.Collections.ArrayList.Count Property

Gets the number of elements actually contained in the ArrayList.

Syntax

public virtual int Count { get; }

Value

A int that specifies the number of elements contained in the current instance.

Remarks

ArrayList.Capacity is the number of elements that the ArrayList can store. ArrayList.Count is the number of elements that are actually in the ArrayList.

ArrayList.Capacity is always greater than or equal to ArrayList.Count. If ArrayList.Count exceeds ArrayList.Capacity while adding elements, the capacity is automatically increased by reallocating the internal array before copying the old elements and adding the new elements.

Retrieving the value of this property is an O(1) operation.
