IEnumerator<T> Implementation

Question

I have a this code

public class SomeClass<T>: IEnumerable<T>
{
    public List<SomeClass<T>> MyList = new List<SomeClass<T>>();

    public IEnumerator<T> GetEnumerator()
    {
        throw new NotImplementedException();
    }
}

How can I Extract a IEnumerator from MyList ?

Thanks StackoverFlower....

Answer 1

This:

public List<SomeClass<T>> MyList = new List<SomeClass<T>>();

Needs to be this:

public List<T> MyList = new List<T>();

then, this should work:

public IEnumerator<T> Getenumerator ()
{
  foreach (var item in MyList){
     yield return item;}
}

You can't have a

List<SomeClass<T>>

that you pull the enumerator for, because you have specified in the interface that the enumerator will return an enumerable item of <T>. You can also change IEnumerable<T> to be

IEnumerable<SomeClass<T>>

and change the Enumerator to be

public IEnumerator<SomeClass<T>> Getenumerator ()
{
  foreach (var item in MyList){
     yield return item;}
}

Answer 2

The trivial option would be return MyList.GetEnumerator().
