Create IEnumerable.Find()

Question

I\'d like to write:

IEnumerable cars;
cars.Find(car => car.Color == \"Blue\")

Can I accomplish this with extension methods? The f

Answer 1

This method already exists. It's called FirstOrDefault

cars.FirstOrDefault(car => car.Color == "Blue");

If you were to implement it yourself it would look a bit like this

public static T Find(this IEnumerable enumerable, Func predicate) {
  foreach ( var current in enumerable ) {
    if ( predicate(current) ) {
      return current;
    }
  }
  return default(T);
}
