问如何使用WampSharp向特定客户端发送消息？

EN

public interface IArgumentsService
{
   [WampProcedure("com.arguments.ping")]
   void Ping();
}

public class ArgumentsService : IArgumentsService
{
   public void Ping()
   {
   }
}

IArgumentsService services = channel.RealmProxy.Services;
ArgumentService callee = new ArgumentService(this);
services.RegisterCallee(callee);

DefaultWampChannelFactory channelFactory = new DefaultWampChannelFactory();
IWampChannel channel = channelFactory.CreateJsonChannel("ws://127.0.0.1:8080/", "realm1");
Task channelOpenTask = channel.Open();
channelOpenTask.Wait();
IArgumentsService proxy = channel.RealmProxy.Services.GetCalleeProxy<IArgumentsService>();

proxy.Ping();
