Syntax
'Declaration
Public ReadOnly Property IsReadOnly As Boolean

virtual property bool IsReadOnly {
bool get () sealed;

abstract IsReadOnly : bool with get
override IsReadOnly : bool with get
final function get IsReadOnly () : boolean
Property Value
Type: System. . :: . .Boolean
This property is always false for all arrays.
Implements
Remarks
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.
