Açıklamalar

Kanallar, uzaktan çağrıları taşımak için the.NET Framework uzaktan iletişim altyapısı tarafından kullanılır. İstemci uzak bir nesneyi çağırdığında, çağrı bir istemci kanalı tarafından gönderilen ve bir sunucu kanalı tarafından alınan bir iletide seri hale getirilir. İleti alındıktan sonra seri durumdan çıkarılır ve işlenir. Döndürülen tüm değerler sunucu kanalı tarafından iletilir ve istemci kanalı tarafından alınır.

IpcChannel sınıfı, sınıfın ve sınıfının işlevselliğini IpcClientChannel birleştiren bir kolaylık sınıfıdırIpcServerChannel.
