IChannelSender.CreateMessageSink(String, Object, String) Метод

Определение

Возвращает приемник сообщений канала, который доставляет сообщения объекту данных канала или по указанному URL-адресу.

public:
 System::Runtime::Remoting::Messaging::IMessageSink ^ CreateMessageSink(System::String ^ url, System::Object ^ remoteChannelData, [Runtime::InteropServices::Out] System::String ^ % objectURI);
public System.Runtime.Remoting.Messaging.IMessageSink CreateMessageSink (string url, object remoteChannelData, out string objectURI);

Public Function CreateMessageSink (url As String, remoteChannelData As Object, ByRef objectURI As String) As IMessageSink

Параметры

url
String

URL-адрес, по которому новый сток доставляет сообщения. Может иметь значение null.

remoteChannelData
Object

Объект данных канала удаленного узла, по которому новый сток доставляет сообщения. Может иметь значение null.

objectURI
String

Когда метод возвращает управление, содержит URI нового приемника сообщений канала, который доставляет сообщения объекту данных канала или по указанному URL-адресу. Этот параметр передается неинициализированным.

Возвращаемое значение

IMessageSink

Приемник сообщений канала, который доставляет сообщения объекту канала данных, по указанному URL-адресу или null, если канал не может подключиться к данному каналу.

Комментарии

Метод CreateMessageSink возвращает приемник сообщений канала, который доставляет сообщения в указанный URL-адрес или объект данных канала. uri Если параметр имеет значениеnull, remoteChannelData параметр используется в качестве целевого объекта для приемника. Параметр url или remoteChannelData параметр могут быть null, но не оба.
