В следующем примере показано, как StringSplitOptions перечисление используется для включения или исключения подстрок, созданных методом String.Split :

Комментарии

Метод String.Split возвращает массив подстрок в заданной строке, разделенный указанными символами или строками. Смежные разделители выдают элемент массива, содержащий пустую строку (""). Одно из полей перечисления StringSplitOptions указывает, должен ли элемент, содержащий пустую строку, включаться в возвращаемый массив.

None Укажите поле для вызова поведения String.Split метода по умолчанию, которое не требует обрезки пробелов и включения пустых подстрок.

Поле TrimEntries доступно только в .NET 5 и более поздних версиях.
