Потокобезопасность

Все члены этого типа являются потокобезопасны. Элементы, которые, как представляется, изменяют состояние экземпляра, фактически возвращают новый экземпляр, инициализированный с новым значением. Как и в случае с любым другим типом, чтение и запись в общую переменную, которая содержит экземпляр этого типа, должна быть защищена блокировкой, чтобы гарантировать безопасность потока.
