C# 无法建立连接，因为目标计算机主动拒绝127.0.0.1:8000内部异常

我是WCF的新手，创建了一个包含2个项目的解决方案，一个是客户端应用程序，另一个是web服务。 当我编译web服务代码时，它不会出错：

namespace Microsoft.ServiceModel.Samples
{

class Program
{
    static void Main(string[] args)
    {

        // Step 1 of the address configuration procedure: Create a URI to serve as the base address.
        Uri baseAddress = new Uri("http://localhost:8888/ServiceModelSamples/Service");

        /* Step 2 of the hosting procedure: Create ServiceHost
         * Use the ServiceHost class to configure and expose a service for use by client applications when you are not using Internet Information Services (IIS) to expose a service.  
         * IIS interacts with a ServiceHost object on your behalf.             
         */
        ServiceHost selfHost = new ServiceHost(typeof(CalculatorService), baseAddress);

        try
        {
            //WSHttpBinding is an interoperable binding that supports distributed transactions and secure, reliable sessions.
            WSHttpBinding ws = new WSHttpBinding();
            ws.Security.Mode = SecurityMode.Message; //Use SOAP message security
            ws.Security.Message.ClientCredentialType = MessageCredentialType.Windows; //Use windows authentication

            // Step 3 of the hosting procedure: Add a service endpoint.
            // Adds a service endpoint to the hosted service with a specified contract, binding, and endpoint address.
            //      The contract is the definition of what functionality the web service offers (i.e. its API)
            //      The binding specifies how the service communicates (protocols, transports, and message encoders)
            //      The address is the name of the endpoint being added to this service host
            selfHost.AddServiceEndpoint(
                typeof(ICalculator),
                ws, 
                "CalculatorService");

            // Step 4 of the hosting procedure: Enable metadata exchange.
            // Controls the publication of service metadata and associated information.
            //      HttpGetEnabled indicates whether to publish service metadata for retrieval using an HTTP/GET request.
            ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
            smb.HttpGetEnabled = true;
            //add the service metadata behavior to the list of service host behaviors
            selfHost.Description.Behaviors.Add(smb);

            // Step 5 of the hosting procedure: Start (and then stop) 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();
        }

        Console.ReadLine();
    }
}

我的app.config看起来像：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <wsHttpBinding>
                <binding name="WSHttpBinding_ICalculator" />
            </wsHttpBinding>
        </bindings>
        <client>
                <endpoint address="http://localhost:8000/ServiceModelSamples/Service"
                binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_ICalculator"
                contract="CalculatorServiceReference.ICalculator" name="WSHttpBinding_ICalculator">

            </endpoint>
        </client>
    </system.serviceModel>
</configuration>

专家能给我指出正确的方向吗？我尝试了许多不同的端点地址，但没有成功。提前谢谢

当您的客户端试图连接到端口8000时，您的服务器托管在8888上。更改服务器或客户端端口，使其匹配

看起来你希望它是8000，而不是8888

Uri baseAddress = new Uri("http://localhost:8000/ServiceModelSamples/Service");

---

我测试了你的代码。我相信您需要像下面这样将服务添加到客户端app.config文件中的基本地址

---

端点地址=”http://localhost:8888/ServiceModelSamples/Service/CalculatorService“

当我编译web服务代码时，它运行时没有错误

仅供参考编译=/=“运行时没有错误”我已更正，您是对的，它确实编译了，但显然不会运行时没有错误，谢谢！我将app.config更改为引用端口8000，因此它们都匹配，但得到的结果是相同的：将其更改为8000，现在获取：没有可以接受消息的端点正在侦听。这通常是由不正确的地址或SOAP操作引起的。有关更多详细信息，请参阅InnerException（如果存在）。您将需要发布新问题！这是一个完全不同的错误，原因完全不同！

Uri baseAddress = new Uri("http://localhost:8000/ServiceModelSamples/Service");
