Question

我使用net.tcp绑定创建了一个WCF服务，并且我能够在我的控制台应用程序中添加一个服务引用而没有错误。

执行此操作后，我尝试在我的控制台应用中自行托管此服务。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它[:: 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();

这是控制台应用程序中的app.config

任何人都可以帮助我。

Answer 1

有可能：

1）防火墙正在阻止请求。看看吧。

2）确保

Net.Tcp侦听器适配器;
Net.Tcp端口共享服务

正在运行（Windows服务）

Answer 2

您的客户端配置的网址为

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

而您的服务已开启

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

控制台应用客户端端点元素的app.config中缺少PORT编号。

Answer 3

可能有多种原因，因为其他答案可以解决问题。但就我而言，问题在安装待处理的 Windows 更新后解决了。
