Syntax

'Declaration
Public Overridable ReadOnly Property Count As Integer

virtual property int Count {
    int get ();
}

abstract Count : int with get
override Count : int with get

Property Value

Type: System. . :: . .Int32
The number of elements actually contained in the ArrayList.

Implements

ICollection. . :: . .Count

Remarks

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

Capacity is always greater than or equal to Count. If Count exceeds 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.
