Array.IsReadOnly Property
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Gets a value indicating whether the Array is read-only.
Assembly: mscorlib (in mscorlib.dll)
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.
