聊天服务器出现.net远程处理问题

我的聊天服务器实现有问题，我不明白为什么它不能按预期工作。

客户端可以向服务器发送消息，但服务器只向自身而不是客户端发送消息。

例如，客户端连接到服务器，然后在聊天中键入"你好"。服务器成功地获取了消息，但随后将消息发布到自己的控制台，而不是发送到连接的客户端。

嗯。。。也许我错过了什么，因为我对.Net远程处理很陌生。也许有人可以帮我弄清楚问题出在哪里。任何帮助都将不胜感激！

代码：

我有一个小接口，用于服务器上的聊天实现

 public class ChatService : MarshalByRefObject, IService
 {
private Dictionary<string, IClient> m_ConnectedClients = new Dictionary<string, IClient>();
private static ChatService _Chat;
private ChatService()
{
    Console.WriteLine("chat service created");
    _Chat = this;
}
public bool Login(IClient user)
{
    Console.WriteLine("logging in: " + user.GetIp());
    if (!m_ConnectedClients.ContainsKey(user.GetIp()))
    {
            m_ConnectedClients.Add(user.GetIp(), user);
        PostMessage(user.GetIp(), user.GetUserName() + " has entered chat");
        return true;
    }
    return false;
}
public bool Logoff(string ip)
{
    Console.WriteLine("logging off: " + ip);
    IClient user;
    if (m_ConnectedClients.TryGetValue(ip, out user))
    {
        PostMessage(ip, user + " has left chat");
        m_ConnectedClients.Remove(ip);
        return true;
    }
    return false;
}
   public bool PostMessage(string ip, string text)
   {
            Console.WriteLine("posting message: " + text + " to: " + m_ConnectedClients.Values.Count);
    foreach (var chatter in m_ConnectedClients.Values)
    {
        Console.WriteLine(chatter.GetUserName() + " : " + chatter.GetIp());
        chatter.SendText(text);
    }
    return true;
}

}

My Server将聊天服务实现为singleton：

RemotingConfiguration.RegisterWellKnownServiceType(typeof(ChatService), "chatservice",  WellKnownObjectMode.Singleton);

我的客户也很直率：

[Serializable]
public class Chat_Client : IClient
{
    private string m_IpAdresse;
    private string m_UserName = "Jonny";
    private string m_Input;
    public Chat_Client(string ip, string username)
    {
        m_IpAdresse = ip;
        m_UserName = username;
    }
    public bool HandleInput(string input)
    {
        if (input.Equals("exit"))
        {
            Client.m_ChatService.Logoff(m_IpAdresse);
            return false;
        }
        m_Input = input;
        Thread sendThread = new Thread(new ThreadStart(SendPostMessage));
        sendThread.Start();
        //Console.WriteLine("post message");
        return true;
    }
    private void SendPostMessage()
    {
        Client.m_ChatService.PostMessage(m_IpAdresse, m_Input);
        Thread thisThread = Thread.CurrentThread;
        thisThread.Interrupt();
        thisThread.Abort();
    }

    public void SendText(string text)
    {
        Console.WriteLine("send text got: " + text);
        Console.WriteLine(text);
    }

主客户端通过以下方式连接到服务器：

public void Connect()
{
        try
        {
            TcpChannel channel = new TcpChannel(0);
            ChannelServices.RegisterChannel(channel, false);
            m_ChatService = (IService)Activator.GetObject(typeof(IService), "tcp://" + hostname + ":9898/Host/chatservice");
            System.Net.IPHostEntry hostInfo = Dns.GetHostEntry(Dns.GetHostName());
            m_IpAdresse = hostInfo.AddressList[0].ToString();
            Chat_Client client = new Chat_Client(m_IpAdresse, m_UserName);
            Console.WriteLine("Response from Server: " + m_ChatService.Login(client));
            string input = "";
            while (m_Running)
            {
                input = Console.ReadLine();
                m_Running = client.HandleInput(input);
            }
        }
}
