IpcClientChannel的ArgumentNullException - 参数名称：URI

Question

当我尝试运行任何方法或读取对象的参数时，我得到ArgumentNullException。该对象有一个来自IpcServerChannel的实例。我该如何处理？

客户端

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

IpcClientChannel clientChannel = new IpcClientChannel(prop, null);
ChannelServices.RegisterChannel(clientChannel, true);

RemotingConfiguration.RegisterWellKnownClientType(typeof(Connector), "ipc://connector");

Connector c = new Connector();
c.Connect(); /* ArgumentNullException - Value cannot be null. Parameter name: URI */

服务器

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

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

// 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);

调用堆栈
