.Where? .WhereNot

Ever have some code like this?

CollectionOfThings.Where(x => !ThingMeetsSomeCondition(x))

If only there were a WhereNot method, then you could use it with a method group, like so

CollectionOfThings.WhereNot(ThingMeetsSomeCondition)

So Where is your WhereNot? Here:

  public static class Extensions

  {

    public static IEnumerable<T> WhereNot<T>(this IEnumerable<T> items, Func<T, bool> predicate)

    {

      return items.Where(x => !predicate(x));

    }

  }

 

Glad that’s done.
