WCF net.tcp通信错误

Question

我创建了一个带有net.tcp绑定的WCF服务，并且能够在我的控制台应用程序中添加对它的服务引用，而不会出现错误。

在这样做之后，我尝试在我的控制台应用程序中自我托管这个服务。服务主机被打开，但是当我使用服务引用对象调用服务中的方法时，我得到了这个异常

‘无法连接到net.tcp://localhost/Design_Time_Addresses/MyWCFServiceLibrary/Service2/.。连接尝试持续的时间跨度为00:00:02.0800000。TCP错误代码10061:无法建立连接，因为目标计算机主动拒绝连接：：1:808。’

这是我的cs文件代码

Main method()

 Service2Client sc2 = new Service2Client();
                Uri baseaddress = new Uri("net.tcp://localhost:8732/Design_Time_Addresses/MyWCFServiceLibrary/Service2/");

                ServiceHost serviceHost = new ServiceHost(typeof(Service2Client), baseaddress);

                serviceHost.Open();

                Console.WriteLine(sc2.GetData(124)); --> exception comes at this point

                Console.ReadLine();

这是控制台应用中的app.config

有人能在这方面帮我吗？

Answer 1

这是可能的：

1) 防火墙正在拦截该请求。看看这个。

2)确保

• Net.Tcp侦听器Adapter;
• Net.Tcp端口共享Service

正在运行(Windows服务)

Answer 2

您的客户端配置的URL为

net.tcp://localhost/Design_Time_Addresses/MyWCFServiceLibrary/Service2/

鉴于您的服务处于打开状态

net.tcp://localhost:8732/Design_Time_Addresses/MyWCFServiceLibrary/Service2/

控制台应用程序客户端终结点元素的app.config中缺少端口号。

Answer 3

可能有多种原因，因为其他答案可以解决问题。但在我的案例中，问题在安装了挂起的windows更新后就解决了。
