WCF 错误“没有端点正在监听...”

Question

我正在创建我的第一个 WCF 应用程序。当它们在同一台计算机上时，客户端可以与主机通信，但从 LAN 上的其他计算机失败。两者都是控制台应用程序。

这是我的代码和配置。

客户端配置：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
   <system.serviceModel>
      <bindings>
         <wsHttpBinding>
            <binding name="WSHttpBinding_ICalculator" />
         </wsHttpBinding>
      </bindings>
      <client>
         <endpoint name="WSHttpBinding_ICalculator"
             address="http://192.168.100.6:8000/ServiceModelSamples/Service/CalculatorService"
             binding="wsHttpBinding" 
             bindingConfiguration="WSHttpBinding_ICalculator"
             contract="ServiceReference1.ICalculator">
             <identity>
                <userPrincipalName value="saumitra\skpaul" />
             </identity>
         </endpoint>
      </client>
   </system.serviceModel>
</configuration>

主机代码：

class Program
{
    static void Main(string[] args)
    {
        // Step 1 Create a URI to serve as the base address.
        Uri baseAddress = new Uri("http://Localhost:8000/ServiceModelSamples/Service");

        // Step 2 Create a ServiceHost instance
        ServiceHost selfHost = new ServiceHost(typeof(CalculatorService), baseAddress);

        try
        {
            // Step 3 Add a service endpoint.
            selfHost.AddServiceEndpoint(typeof(ICalculator), new WSHttpBinding(), "CalculatorService");

            // Step 4 Enable metadata exchange.
            ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
            smb.HttpGetEnabled = true;
            selfHost.Description.Behaviors.Add(smb);

            // Step 5 Start the service.
            selfHost.Open();
            Console.WriteLine("The service is ready.");
            Console.WriteLine("Press <ENTER> to terminate service.");
            Console.WriteLine();
            Console.ReadLine();

            // Close the ServiceHostBase to shutdown the service.
            selfHost.Close();
        }
        catch (CommunicationException ce)
        {
            Console.WriteLine("An exception occurred: {0}", ce.Message);
            selfHost.Abort();
        }
    }
}

你可以从this post得到一个想法

您也可以使用套接字编程。 Here 是一个非常好的多客户端、双向通信套接字编程示例。

Answer 2

首先确保从客户端使用的地址是服务器的正确位置。您的代码目前被硬编码到目的地...

<endpoint address="http://192.168.100.6:8000/

...但是服务器实际上是在 192.168.100.6 上运行的吗？
