c# - channel 'tcp' 已经注册

Question

我希望给定的应用程序(Windows 服务)充当远程服务器和远程客户端。在生产环境中，我将运行我的应用程序的两个实例，通过 .NET Remoting 相互监控，并相应地报告故障。

我已经写了一个基本的部分，并得到“ channel ‘tcp’已经注册”异常。我想以编程方式设置 channel 配置。

正如其他人所说，如果您不指定 channel 名称，代码默认使用“tcp”并且每个 channel 都必须有一个唯一的名称:因此为您打开的每个 channel 指定一个唯一的名称...

   int tcpPort = 52131;
    // ------------------------------------------------------------
    BinaryServerFormatterSinkProvider serverProv =
        new BinaryServerFormatterSinkProvider();
    serverProv.TypeFilterLevel = TypeFilterLevel.Full; 
    RemotingConfiguration.CustomErrorsMode = CustomErrorsModes.Off;

    serverProv.TypeFilterLevel = TypeFilterLevel.Full;
    IDictionary propBag = new Hashtable();
    // -----------------------------------------
    bool isSecure = [true/false];
    propBag["port"] = tcpPort ;
    propBag["typeFilterLevel"] = TypeFilterLevel.Full;
    propBag["name"] = "UniqueChannelName";  // here enter unique channel name
    if (isSecure)  // if you want remoting comm to be secure and encrypted
    {
        propBag["secure"] = isSecure;
        propBag["impersonate"] = false;  // change to true to do impersonation
    }
    // -----------------------------------------
    tcpChan = new TcpChannel(
        propBag, null, serverProv);
    ChannelServices.RegisterChannel(tcpChan, isSecure);
    // --------------------------------------------

    string uRI = MyUniversalResourceIndicatorName;
    // ---------------------------------------------

    RemotingConfiguration.RegisterWellKnownServiceType(
        typeof(ImportServiceManager), uRI ,
        WellKnownObjectMode.SingleCall);
