Enumerating through instances of derived class instances



if have numerous instances of different derived classes (with classes derived same base class), how might possibly enumerate through them, besides them being in list?

 

to enumerate them, need in collection.


if want use instances, "easiest" method typically make array:

  foreach(var item in new baseclass[] {instance1, instance2, instance3}) {    // use item }


if you're making method, can use iterators:

  ienumerable<baseclass> getenumerator() {    yield return instance1;    yield return instance2;    yield return instance3; }
