Property Value

This property is always false for all arrays.

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

If you require a read-only collection, use a System.Collections class that implements the System.Collections.IList interface.

An array that is read-only does not allow the addition, removal, or modification of elements after the array is created.

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