Array.IList.Add Method (Object)


Calling this method always throws a NotSupportedException exception.

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

Private Function Add (
	value As Object
) As Integer
	Implements IList.Add


Type: System.Object

The object to be added to the IList.

Return Value

Type: System.Int32

Adding a value to an array is not supported. No value is returned.

Exception Condition

The IList has a fixed size.

Ordinarily, an IList.Add implementation adds a member to a collection. However, because arrays have a fixed size (the IsFixedSize property always returns true), this method always throws a NotSupportedException exception.

This member is an explicit interface member implementation. It can be used only when the Array instance is cast to an IList interface.
