合同:
[ServiceContract]
public interface IDaemonService {
[OperationContract]
void SendNotification(DaemonNotification notification);
}
服务:
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class DaemonService : IDaemonService {
public DaemonService() {
}
public void SendNotification(DaemonNotification notification) {
App.NotificationWindow.Notify(notification);
}
}
在 WPF 应用程序中,我执行以下操作:
using (host = new ServiceHost(typeof (DaemonService), new[] {new Uri("net.pipe://localhost")})) {
host.AddServiceEndpoint(typeof (IDaemonService), new NetNamedPipeBinding(), "AkmDaemon");
host.Open();
}
此 WPF 应用程序启动另一个应用程序,如下所示:
Task.Factory.StartNew(() => {
var tpm = new Process { StartInfo = { FileName = "TPM" } };
tpm.Start();
}
});
名为 TPM 的应用程序正常启动。然后我在 Visual Studio 的调试菜单中附加到进程,我看到客户端说没有人在端点监听。
这是客户端:
[Export(typeof(DaemonClient))]
public class DaemonClient : IHandle<DaemonNotification> {
private readonly ChannelFactory<IDaemonService> channelFactory;
private readonly IDaemonService daemonServiceChannel;
public DaemonClient(IEventAggregator eventAggregator) {
EventAggregator = eventAggregator;
EventAggregator.Subscribe(this);
channelFactory = new ChannelFactory<IDaemonService>(new NetNamedPipeBinding(),
new EndpointAddress("net.pipe://localhost/AkmDaemon"));
daemonServiceChannel = channelFactory.CreateChannel();
}
public IEventAggregator EventAggregator { get; private set; }
public void Handle(DaemonNotification message) {
daemonServiceChannel.SendNotification(message); //Here I see that the endpoint //is not found
}
public void Close() {
channelFactory.Close();
}
}
EndpointNotFoundException 在“net.pipe://localhost/AkmDaemon”没有监听端点...... blablabla
