事件和IPCServerChannel引发TargetInvocationException

Question

For some bizarre problem when I try to use Events and IPC Remoting am getting these exceptions, which would be the point? Has anyone had this problem?

Client

BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();

IDictionary prop = new Hashtable();
prop["name"] = "remote";
prop["secure"] = true;
prop["priority"] = 1;
prop["tokenImpersonationLevel"] = TokenImpersonationLevel.Impersonation;

IpcClientChannel clientChannel = new IpcClientChannel(prop, clientProvider);
ChannelServices.RegisterChannel(clientChannel, true);
RemotingConfiguration.RegisterWellKnownClientType(typeof(Connector), "ipc://connector/connector");

Connector c = new Connector();
c.OnX += new Connector.X(c_OnX);
c.Connect();

Server

BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();
serverProvider.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full;

IDictionary prop = new Hashtable();
prop["name"] = "remote";
prop["secure"] = true;
prop["priority"] = 1;
prop["portName"] = "connector";
prop["tokenImpersonationLevel"] = TokenImpersonationLevel.Impersonation;
prop["authorizedGroup"] = new SecurityIdentifier("S-1-1-0").Translate(typeof(NTAccount)).ToString(); /* Everyone or Todos =p  - Sou amador, e dai ? */

// Create and register an IPC channel
IpcServerChannel serverChannel = new IpcServerChannel(prop, serverProvider);
ChannelServices.RegisterChannel(serverChannel, true);

// Expose an object
RemotingConfiguration.RegisterWellKnownServiceType(typeof(Connector), "connector", WellKnownObjectMode.Singleton);

Answer 1

Could not load file or assembly 'Vex Connector Client,...'

Pretty standard kind of error for a Remoting app, it just can't find the assembly. Make sure it's there, preferably in the same directory as the exe. Use Fuslogvw.exe if you have trouble diagnosing the reason it cannot find the assembly.

---

The fuslogvw traces show the problem clearly. The server is looking for "vex connector client.exe" in its own directory, Final Vex Connector/Vex Connector/Vex Connector Service/ bin/Debug/. But the file isn't there, it is stored in Final Vex Connector/Vex Connector/Vex Connector Client/bin/Debug/

Copy the file to fix the problem.

If you find it distasteful that the server needs the client.exe then put the classes they share in a separate project.
