Комментарии

Важно!

Вызов методов из классов, реализующих этот интерфейс, для ненадежных данных представляет угрозу безопасности. Вызывайте методы классов, реализующих этот интерфейс, только для надежных данных. Дополнительные сведения см. в разделе Проверка всех входных данных.

Отправляя сторона каналов должна предоставлять IChannelSender интерфейс .

Свойства

ChannelName	Возвращает имя канала. (Унаследовано от IChannel)
ChannelPriority	Возвращает приоритет канала. (Унаследовано от IChannel)

Методы

CreateMessageSink(String, Object, String)	Возвращает приемник сообщений канала, который доставляет сообщения объекту данных канала или по указанному URL-адресу.
Parse(String, String)	Возвращает URI-объект в качестве внешнего параметра и URI текущего канала в качестве возвращаемого значения. (Унаследовано от IChannel)
