Question

I’m looking for some type of iterator/enumerator that can write to the backing collection. As I understand it c# enumerators are read-only.

Answer 1

There’s nothing already existing in C# to do such a thing.

You’re right IEnumerator’s Current property is defined as a getter only.

You’d need to write a new class and/or interface to support such a thing.

interface IOutputable<T> {
  IOutputer<T> GetOutputer();
  }

interface IOutputer<T> {

  T Current { set; }

  bool MoveNext();
  void Reset();
  }
