A couple of weeks ago i discovered Enumerable.OfType<TResult> when i let Resharper rewrite my code as a Linq statement. Here is the original code:

var selectedPersons = new List<personSelectItem>();
foreach(var selectedItem in selectedItems)
{
 var selectedPerson = selectedItem as PersonSelectItem;
 if (selectedPerson == null) continue;
 selectedPersons.Add(selectedPerson);
}

And here is how it looks after the rewrite:

var selectedPersons = selectedItems.OfType<personSelectItem>().ToList();

Yup, the Resharper license was definitely worth it’s money.
