WCF：Net.TCP多个绑定，相同端口，不同IP地址

我遇到了问题。我是 WCF 的新手，因此我们将不胜感激。

这是我的代码：

public static void StartHosts()
    {
        try
        {
            // Create a new host
            ServiceHost host = new ServiceHost(typeof(ServerTasks));

            List<IPAddress> ips = new List<IPAddress>(Dns.GetHostAddresses(Dns.GetHostName()));
            if (IPAddress.Loopback != null)
                ips.Add(IPAddress.Loopback);

            ips.RemoveAll(i => i.AddressFamily != AddressFamily.InterNetwork);

            foreach (var ip in ips)
            {
                string uri = string.Empty;

                // Formulate the uri for this host
                uri = string.Format(
                    "net.tcp://{0}:{1}/ServerTasks",
                    ip.ToString(),
                    ServerSettings.Instance.TCPListeningPort
                );


                // Add the endpoint binding
                host.AddServiceEndpoint(
                    typeof(ServerTasks),
                    new NetTcpBinding(SecurityMode.Transport) { TransferMode = TransferMode.Streamed },
                    uri
                );

            }



            // Add the meta data publishing
            var smb = host.Description.Behaviors.Find<ServiceMetadataBehavior>();
            if (smb == null)
                smb = new ServiceMetadataBehavior();

            smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
            host.Description.Behaviors.Add(smb);

            host.AddServiceEndpoint(
                ServiceMetadataBehavior.MexContractName,
                MetadataExchangeBindings.CreateMexTcpBinding(),
                "net.tcp://localhost/ServerTasks/mex"
            );

            // Run the host
            host.Open();
        }
        catch (Exception exc)
        {
            DebugLogger.WriteException(exc);
        }
    }

行上抛出异常：“host.Open();”

例外的是：

系统无效操作异常URI“net.tcp://192.168.1.45:4329/ServerTasks”的注册已存在。

感谢科拉扎提供的信息！

我已经想出了如何实现这一目标。我的做法完全错误。

我的最终目标是让该服务侦听计算机上可用的每个 IP 地址。尝试单独绑定到每个地址是错误的方法。

相反，我只需要将服务绑定到机器的主机名（不是“localhost”）并且 WCF 自动侦听所有适配器。

这是更正后的代码：

public static void StartHosts()
    {
        try
        {
            // Formulate the uri for this host
            string uri = string.Format(
                "net.tcp://{0}:{1}/ServerTasks",
                Dns.GetHostName(),
                ServerSettings.Instance.TCPListeningPort
            );

            // Create a new host
            ServiceHost host = new ServiceHost(typeof(ServerTasks), new Uri(uri));

            // Add the endpoint binding
            host.AddServiceEndpoint(
                typeof(ServerTasks),
                new NetTcpBinding(SecurityMode.Transport) 
                        { 
                            TransferMode = TransferMode.Streamed
                        },
                uri
            );

            // Add the meta data publishing
            var smb = host.Description.Behaviors.Find<ServiceMetadataBehavior>();
            if (smb == null)
                smb = new ServiceMetadataBehavior();

            smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
            host.Description.Behaviors.Add(smb);

            host.AddServiceEndpoint(
                ServiceMetadataBehavior.MexContractName,
                MetadataExchangeBindings.CreateMexTcpBinding(),
                "net.tcp://localhost/ServerTasks/mex"
            );

            // Run the host
            host.Open();
        }
        catch (Exception exc)
        {
            DebugLogger.WriteException(exc);
        }
    }
