Array.IsReadOnly Property

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

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

public bool IsReadOnly { get; }

Property Value

Type: System.Boolean
This property is always false for all arrays.

Implements

IList.IsReadOnly

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.
