Array::IList::Add Method

Calling this method always throws a NotSupportedException exception.

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

private:
virtual int Add(
	Object^ value
) sealed = IList::Add

Parameters

value
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.

Implements

IList::Add(Object)

ExceptionCondition
NotSupportedException

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.
