IsReadOnly Property

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Gets a value indicating whether the Array is read-only.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public ReadOnly Property IsReadOnly As Boolean
public bool IsReadOnly { get; }
public:
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

IList. . :: . .IsReadOnly

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.
