请教WCF的net .tcp绑定的问题

Question

这是我的代码，有两种宿主方式，我用的是宿主在控制台里面也就是自宿主，而且下面的代码也能启动起来，我是在启动的状态下添加service服务引用的，但是我添加服务的时候缺报错。请问是怎么回事？
Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:8087/'.
Could not connect to net.tcp://localhost:8087/. The connection attempt lasted for a time span of 00:00:01.9531250. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8087. 
No connection could be made because the target machine actively refused it 127.0.0.1:8087
If the service is defined in the current solution, try building the solution and adding the service reference again.

Answer 1

添加service服务引用的时候必须使用http开头的地址，所以你必须保证你的服务里有类似下面的节配置：
         <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8087/ChatService"/>
          </baseAddresses>
        </host>当然，如果你完全使用代码来配置也可以，请测试以下代码：
        static void Main(string[] args)
        {
            Uri baseAddress = new Uri("http://localhost:8087/ChatService");
            using (ServiceHost host = new ServiceHost(typeof(ChatService), baseAddress))
            {
                BindingElement bindingElement = new TcpTransportBindingElement();
                CustomBinding binding = new CustomBinding(bindingElement);                 host.AddServiceEndpoint(typeof(IChat), binding, "net.tcp://localhost:8087/ChatService");
                ServiceMetadataBehavior metadataBehavior; metadataBehavior = host.Description.Behaviors.Find<ServiceMetadataBehavior>();
                if (metadataBehavior == null)
                {
                    metadataBehavior = new ServiceMetadataBehavior();
                    host.Description.Behaviors.Add(metadataBehavior);
                }
                host.Open();
                Console.Write("The service is ready,press any key to exit!");
                Console.ReadLine();
            }
        }

楼上的，报错：
HTTP could not register URL http://+:8087/ChatService/ because TCP port 8087 is being used by another application.

那你试试用配置文件呢？通过service服务引用添加客户端我只在app.config下设置services写过，通过代码方式没做过。
我一开始使用WCF的时候也是添加service服务引用，那是看着例子设置的app.config。后来发现可以通过代码设置的时候，已经不再添加service服务引用了，客户端直接代码设置，引用公共接口dll，这样效率很高，所以你这种写法我没有试过，你可以考虑将地址写在配置文件中。类似这样的配置文件节点，是可以正常添加引用的，引用地址：http://localhost:8000/ckth/service
<services>
      <service name="ConsoleApplication1.DataManagerService"
               behaviorConfiguration="DataManagerBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8000/ckth/service"/>
          </baseAddresses>
        </host>
        <!-- this endpoint is exposed at: net.tcp://localhost:9000/servicemodelsamples/service  -->
        <endpoint address="net.tcp://localhost:9000/ckth/service"
                  binding="netTcpBinding"
                  bindingConfiguration="Binding1" 
                  contract="ConsoleApplication1.IDataManager" />
        <!-- the mex endpoint is exposed at http://localhost:8000/ServiceModelSamples/service/mex -->
        <endpoint address="mex" 
                  binding="mexHttpBinding"
                  contract="IMetadataExchange" />
      </service>
    </services>
        static void Main(string[] args)
        {
            // Create a ServiceHost for the CalculatorService type.
            using (ServiceHost serviceHost = new ServiceHost(typeof(DataManagerService)))
            {
                // Open the ServiceHost to create listeners and start listening for messages.
                
                serviceHost.Open();
                // The service can now be accessed.                Console.WriteLine("服务已开启.");
                Console.WriteLine("按 <ENTER> 终止服务.");
                Console.WriteLine();
                Console.ReadLine();
                serviceHost.Close();
            }
        }

楼上的，WCF对IIS有什么要求吗？我的是IIS 5.1，但是我试过宿主到IIS中绑定用的是wsHttpBinding，这样是没有问题的
