Boolean

This property is always true for all arrays.

IsFixedSize

Remarks

Array implements the IsFixedSize property because it is required by the System.Collections.IList interface.

An array with a fixed size does not allow the addition or removal of elements after the array is created, but it allows the modification of existing elements.

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