using enumerator between class and object

Question

I have an array of struct in an object. I want to pass each of these struct in the array to the class using a foreach loop so that I can display each struct in the class. Here is the code in the object to pass the struct :

public IEnumerator recup_voitures()
{
    foreach (voiture v in _arrVCollection)
    {
        yield return (v);
    }
}

and I try to reccuperate these in the class using :

foreach (CarCollection.voiture o in collection.recup_voitures())
{
   //some console.writeline to display whats inside each struct 
}

this dosen't work. I get an error that say that it dosen't have a public GetEnumerator. Can anyone help me to figure this out?

Answer 1

You need to return an IEnumerable. (preferably IEnumerable<T>)

foreach operates on (objects that look like) IEnumerable<T> and calls GetEnumerator() to enumerate over the collection.
