C# 在WCF中寻址服务时出现问题

我正在使用wcf编写一个服务。 我创建了一个包含两个项目的解决方案：

• 库：存储有关服务的文件（包含该服务的接口和相应实现）的项目。这个项目是一个图书馆项目
• 托管应用程序托管这些服务的项目（自托管）。由于这个原因，这个项目是一个可执行项目，它有一个配置文件，我在其中放置了配置服务所需的信息

我还编写了一个客户端来调用该服务。这将被称为客户端应用程序

我有服务。以下是接口和实现（库项目）：

以下是可执行项目（托管应用程序）中的

App.config

：

但如果我这样做，就会出现不匹配错误：

这封信是写给你的 'http://localhost:8081/Service1/GoInto/Svc' 无法在接收器上处理， 由于地址筛选器在上不匹配 端点调度器。检查一下 发送方和接收方的 我同意

为什么不工作？

必须在一个位置指定基址，要么在ServiceHost构造函数中，要么在元素中。如果您在这两个位置都有，WCF将抛出一个异常，说明您有两个相同方案（HTTP）的基址

可能发生的情况是，托管项目的app.config上的服务名称不匹配，因此无法获取配置（而您得到的是一个默认端点，其地址与基址相同）。尝试在宿主代码上添加foreach循环，您应该可以看到服务正在侦听的端点的地址

                Console.WriteLine("Opening host...");
            host.Open();

            foreach (ServiceEndpoint endpoint in host.Description.Endpoints)
            {
                Console.WriteLine("Endpoint:");
                Console.WriteLine("   Address: {0}", endpoint.Address.Uri);
                Console.WriteLine("   Binding: {0}", endpoint.Binding);
                Console.WriteLine("   Contract: {0}", endpoint.Contract.Name);
            }

            Console.WriteLine("Waiting...");
