【问题描述】：
对于一些奇怪的问题，当我尝试使用事件和 IPC 远程处理时，我得到了这些异常，重点是什么？有人遇到过这个问题吗？
客户
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();
服务器
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);

FusionLog=WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

除非您被困在 .NET 2.0 或更低版本，否则您不应该使用 Remoting。它已被 WCF 弃用。
