Filtering collections in C#

If you’re using C# 3.0 you can use linq, which is way better and way more elegant:

List<int> myList = GetListOfIntsFromSomewhere();

// This will filter ints that are not > 7 out of the list; Where returns an
// IEnumerable<T>, so call ToList to convert back to a List<T>.
List<int> filteredList = myList.Where(x => x > 7).ToList();

If you can’t find the .Where, that means you need to import using System.Linq; at the top of your file.
