Property Value

The number of elements that the CollectionBase can contain.

Exception typeCondition

ArgumentOutOfRangeException

Capacity is set to a value that is less than Count.

OutOfMemoryException

There is not enough memory available on the system.

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

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.

The capacity can be decreased by setting the Capacity property explicitly. When the value of Capacity is set explicitly, the internal array is also reallocated to accommodate the specified capacity.

Retrieving the value of this property is an O(1) operation; setting the property is an O(n) operation, where n is the new capacity.
