You can use the yield keyword to hold and return the data to the caller. See below for an example.
Public static IEnumerable ExampleMethod()
{
List li = new List();
foreach (int item in li)
{
if (item 3)
{
li.Add(i);
}
}
//Instead of the above, you could use Yield like below
foreach (int item in ListCollection)
{
if (item 3) yield return item;
}
}
