  • Is there a difference between iterable and enumerable?

  • c# - Theres a most performant way to check that a collection has . . .
    public static bool HasOne<T>(this IEnumerable<T> enumerable) { var enumerator = enumerable GetEnumerator(); return enumerator MoveNext() !enumerator MoveNext(); } another implementation (slighly slower but 100% sure will work effectivly on Linq to Entities) would be : public static bool HasOne<T>(this IEnumerable<T> enumerable) {
  • Ordered enumeration: IEnumerable or Array (in C#)?
