Using IEnumerable without foreach loop

Question

I've gotta be missing something simple here.

Take the following code:

public IEnumerable<int> getInt(){
  for(int i = 0; i < 10; i++){
   yield return i;
  }
}

I can call this with:

foreach (int j in obj.getInt()){
  //do something with j
}

How can I use the getInt method without the foreach loop:

IEnumerable<int> iter = obj.getInt();
// do something with iter ??

Thanks.

For those wondering why I'd want this. I'm iterating two things:

IEnumerator<int> iter = obj.getInt().GetEnumerator();
foreach(object x in xs){
  if (x.someCondition) continue;
  iter.MoveNext();
  int n = iter.current();
  x.someProp = n;
  etc...
}

You can get a reference to the Enumerator, using the GetEnumerator method, then you can use the MoveNext() method to move on, and use the Current property to access your elements:

var enumerator = getInt().GetEnumerator();
while(enumerator.MoveNext())
{
    int n = enumerator.Current;
    Console.WriteLine(n);
}
