Does Class need to implement IEnumerable to use Foreach

Question

This is in C#, I have a class that I am using from some else\'s DLL. It does not implement IEnumerable but has 2 methods that pass back a IEnumerator. Is there a way I can u

Answer 1

You could always wrap it, and as an aside to be "foreachable" you only need to have a method called "GetEnumerator" with the proper signature.

class EnumerableAdapter
{
  ExternalSillyClass _target;

  public EnumerableAdapter(ExternalSillyClass target)
  {
    _target = target;
  }

  public IEnumerable GetEnumerator(){ return _target.SomeMethodThatGivesAnEnumerator(); }

}
