방법: 채널 팩터리를 만들어 채널을 만들고 관리하는 데 사용
ph x="1" /> 클래스에서는 서비스 엔드포인트에서 메시지를 받거나 보내기 위해 클라이언트에서 사용하는 여러 형식의 이중 채널을 만들고 관리하는 방법을 제공합니다.
예시
다음 코드에서는 채널 팩터리를 만드는 방법과 이 채널 팩터리를 사용하여 채널을 만들고 관리하는 방법을 보여 줍니다.
// Construct InstanceContext to handle messages on the callback interface.
// An instance of ChatApp is created and passed to the InstanceContext.
InstanceContext site = new InstanceContext(new ChatApp());
// Create the participant with the given endpoint configuration.
// Each participant opens a duplex channel to the mesh.
// Participant is an instance of the chat application that has opened a channel to the mesh.
using (DuplexChannelFactory<IChatChannel> cf =
new DuplexChannelFactory<IChatChannel>(site,"ChatEndpoint"))
{
X509Certificate2 issuer = GetCertificate(
StoreName.CertificateAuthority,
StoreLocation.CurrentUser, "CN=" + issuerName,
X509FindType.FindBySubjectDistinguishedName);
cf.Credentials.Peer.Certificate =
GetCertificate(StoreName.My,
StoreLocation.CurrentUser,
"CN=" + member,
X509FindType.FindBySubjectDistinguishedName);
cf.Credentials.Peer.PeerAuthentication.CertificateValidationMode =
X509CertificateValidationMode.Custom;
cf.Credentials.Peer.PeerAuthentication.CustomCertificateValidator =
new IssuerBasedValidator();
using (IChatChannel participant = cf.CreateChannel())
{
// Retrieve the PeerNode associated with the participant and register for online/offline events.
// PeerNode represents a node in the mesh. Mesh is the named collection of connected nodes.
IOnlineStatus ostat = participant.GetProperty<IOnlineStatus>();
ostat.Online += new EventHandler(OnOnline);
ostat.Offline += new EventHandler(OnOffline);
Console.WriteLine("{0} is ready", member);
Console.WriteLine("Press <ENTER> to send the chat message.");
// Announce self to other participants.
participant.Join(member);
Console.ReadLine();
participant.Chat(member, "Hi there - I am chatting");
Console.WriteLine("Press <ENTER> to terminate this instance of chat.");
Console.ReadLine();
// Leave the mesh and close the client.
participant.Leave(member);
}
