Exemplos

O exemplo de código a seguir cria um ForEachLoopenumerador SMO e hospeda-o em um ForEachEnumeratorHost, em que ele é adicionado como no ForEachEnumeratorForEachLoop. Retornando um ForEachSMOEnumerator, um SMODataFileEnumerator é criado como um System.Collections.IEnumerator e iterado ao longo do uso MoveNext e Current. Depois que o índice tiver passado o final da coleção, ele Reset será usado para redefinir o iterador.
