virtual int System.Collections.IList.Add(System::Object ^ value) = System::Collections::IList::Add;int IList.Add(object value);abstract member System.Collections.IList.Add : obj -> int
override this.System.Collections.IList.Add : obj -> intFunction Add (value As Object) As Integer Implements IList.AddAdding a value to an array is not supported. No value is returned.
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.
