ローカルではない他のコンピュータに接続する

Question

私は自分のパソコンから他のパソコンに接続しようとしています。私は自宅にいるものをインターネットに接続しています。だから私は、プログラムMyIpAdressで他のPCをチェックし、それは次のようである：38.xx.xx.xx. そして、私はこのプログラムを持っています。サーバー：

public delegate void StatusChangedHandler(object sender, StatusChangedEventArgs e); 

    public class StatusChangedEventArgs : EventArgs 
    { 
     // This will store our only parameter/event argument, which is the event message 
     private string EventMsg; 

     // We need to define this property in order to retrieve the message in the event handler, back in Form1.cs 
     public string EventMessage 
     { 
      get 
      { 
       return EventMsg; 
      } 
     } 

     // The constructor will set the message 
     public StatusChangedEventArgs(string strEventMsg) 
     { 
      EventMsg = strEventMsg; 
     } 
    } 

    class Monitor 
    { 
     // Will store the IP address passed to it 
     IPAddress ipAddress; 

     // The constructor sets the IP address to the one retrieved by the instantiating object 
     public Monitor(IPAddress address) 
     { 
      ipAddress = address; 
     } 

     // Declare the event that we'll fire later 
     public event StatusChangedHandler StatusChangedEvent; 
     // The thread that will hold the connection listener 
     private Thread thrListener; 
     // The TCP object that listens for connections 
     private TcpListener tlsServer; 
     // The thread that will send information to the client 
     private Thread thrSender; 
     // Will tell the while loop to keep monitoring for connections 
     bool ServRunning = false; 

     public void StartMonitoring() 
     { 
      // Get the IP of the first network device, however this can prove unreliable on certain configurations 
      IPAddress ipaLocal = ipAddress; 
      if (tlsServer == null) 
      { 
       // Create the TCP listener object using the IP of the server and the specified port 
       tlsServer = new TcpListener(ipaLocal, 1986 ); 
      } 
      // Start the TCP listener and listen for connections 
      tlsServer.Start(); 

      // The while loop will check for true in this before checking for connections 
      ServRunning = true; 

      // Start the new tread that hosts the listener 
      thrListener = new Thread(KeepListening); 
      thrListener.Start(); 
     } 

     private void KeepListening() 
     { 
      TcpClient tclServer; 
      // While the server is running 
      while (ServRunning == true) 
      { 
       // Accept a pending connection 
       tclServer = tlsServer.AcceptTcpClient(); 
       // Start a new thread where our new client who just connected will be managed 
       thrSender = new Thread(new ParameterizedThreadStart(AcceptClient)); 
       // The thread calls the AcceptClient() method 
       thrSender.Start(tclServer); 
      } 
     } 

     // Occures when a new client is accepted 
     private void AcceptClient(object newClient) 
     { 
      // Set the argument/parameter to a message explaining what just happened 
      StatusChangedEventArgs evArg = new StatusChangedEventArgs("A client was successfully accepted."); 
      // Fire the event because a new client was accepted 
      StatusChangedEvent(this, evArg); 
     } 
    } 

をしかし、私はテキストボックスにipadressで埋める場合：38.xxx.xxx.xx、
をさせていただきますこのエラーが表示されます：

An unhandled exception of type 'System.Net.Sockets.SocketException' occurred in System.dll Additional information: The requested address is not valid in its context

ローカルIPアドレスしか表示されませんか？
しかし、それを変更する方法、それはまた、ローカルIpadressesを見つけることはありません？

そして、これはクライアントアプリケーションです：

tcpServer.Connect（IPAddress.Any、1986）：だから私はこの行を変更フォーム {

private string UserName = "Unknown"; 
    private StreamWriter swSender; 
    private StreamReader srReceiver; 
    private TcpClient tcpServer;

     srReceiver = new StreamReader(tcpServer.GetStream());

：

公共部分クラスをForm1 ;

が、私は、サーバーアプリケーションを実行する場合、私はこのエラーを取得します：

私はクライアントによって同じエラーを取得する：

型「System.Net.Sockets.SocketException」の未処理の例外が発生した

System.dllの

追加情報に：要求されたアドレスは

が

いただきありがとうございます、そのコンテキストで有効ではありません

私はあなたに2つの画像を示します：これはサーバーアプリケーションです。私はこのように、クライアントアプリケーションのコードを変更した場合

そして：

tcpServer.Connect（ip-addrで、1986）それは

これは、クライアントアプリ、それdoesntのが仕事であるに動作します;それから私は、このエラーが発生します。

追加情報：接続の試みは、接続先が適切に一定期間後に応答しなかったため、接続されたホストが応答に失敗したため、または確立された接続が失敗した失敗した

しかし、私はすることができます私はその後、変更しなければならないもの

private void InitializeConnection() 
     { 
      // Parse the IP address from the TextBox into an IPAddress object 
      ipAddr = IPAddress.Parse(txtServerIP.Text); 
      // Start a new TCP connections to the chat server 
      tcpServer = new TcpClient(); 
      tcpServer.Connect(IPAddress.Any, 1986); 

      // Helps us track whether we're connected or not 
      Connected = true; 
      // Prepare the form 
      UserName = txtUserName.Text; 

      // Disable and enable the appropriate fields 
      txtServerIP.Enabled = false; 
      txtUserName.Enabled = false; 
      txtMessage.Enabled = true; 
      btnSend.Enabled = true; 
      btnConnect.Text = "Disconnect"; 

      // Send the desired username to the server 
      swSender = new StreamWriter(tcpServer.GetStream()); 
      swSender.WriteLine(txtUserName.Text); 
      swSender.Flush(); 

      // Start the thread for receiving messages and further communication 
      thrMessaging = new Thread(new ThreadStart(ReceiveMessages)); 
      thrMessaging.Start(); 
     } 

：クライアントプログラムでは、他のPC

をピン私はこれを持っていますか？

Answer 1

おそらく、両方のPCのアプリケーションのファイアウォールのポートでTCP接続を許可する必要があります。ネットワークとの接続が許可されていることを確認してください。
