Array.IList.Add Method (Object)
Calling this method always throws a NotSupportedException exception.
Assembly: mscorlib (in mscorlib.dll)
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.
