Property Value

Type: System. . :: . .Boolean
true if the ArrayList is read-only; otherwise, false. The default is false.

Implements

IList. . :: . .IsReadOnly

Remarks

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

A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection; therefore, if changes are made to the underlying collection, the read-only collection reflects those changes.

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