C# 客户可以'；在Windows服务中找不到WCF的端点元素

我正在尝试将WCF服务放入Windows服务中。我使用svcutil来使用CalculatorService.cs和output.config。我将output.config的内容放入App.config，并在其中编写一个客户端，包括CalculatorService.cs。当它运行时，我得到一个错误，“在ServiceModel客户机配置部分中找不到引用约定'IAnswerResult'的默认端点元素”。在我的客户端中，我刚刚复制了向导所说的要使用的内容：

protected void Page_Load(object sender, EventArgs e)
{
AnswerResultClient client = new AnswerResultClient(); // error here
client.QuestionAnswered("1", "2", "3");
}

在客户端（已生成）的App.config中，我有以下内容，但它告诉我合同“IAnswerResult”无效。我不知道为什么。。。它是由svcutil生成的

  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IAnswerResult" />
      </basicHttpBinding>
      <netTcpBinding>
        <binding name="NetTcpBinding_IAnswerResult" />
      </netTcpBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost:6255/CalculatorService" binding="basicHttpBinding"
          bindingConfiguration="BasicHttpBinding_IAnswerResult" contract="IAnswerResult"
          name="BasicHttpBinding_IAnswerResult" />
      <endpoint address="net.tcp://localhost:6256/CalculatorService"
          binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IAnswerResult"
          contract="IAnswerResult" name="NetTcpBinding_IAnswerResult">

          <servicePrincipalName value="host/Server2012" />
        </identity>
      </endpoint>
    </client>
  </system.serviceModel>

Windows服务/WCF服务中的App.config：

namespace EternaService
{
    [ServiceContract(Namespace = "http://EternaService")]

    public interface IAnswerResult
    {
        [OperationContract]
        string QuestionAnswered(string person_int, string course_int, string lesson_int);
    }


    public class CalculatorService : IAnswerResult
    {
        public string QuestionAnswered(string person_int, string course_int, string lesson_int)
        {
            string result = "";
            // Have input, now do something with it.
            return result;
        }

    }

    public partial class EternaService : ServiceBase
    {
        public ServiceHost serviceHost = null;

        public EternaService()
        {
            this.CanStop = true;
            this.CanHandlePowerEvent = true;
            this.CanHandleSessionChangeEvent = true;
            this.CanPauseAndContinue = true;
            this.CanShutdown = true;

            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {

            if (serviceHost != null)
            {
                serviceHost.Close();
            }
            serviceHost = new ServiceHost(typeof(CalculatorService));
            serviceHost.Open();
        }

在客户端计算器服务类中：

[System.ServiceModel.ServiceContractAttribute(Namespace= "http://CADEEternaService", ConfigurationName="IAnswerResult")]
public interface IAnswerResult
{

    [System.ServiceModel.OperationContractAttribute(Action= "http://CADEEternaService/IAnswerResult/QuestionAnswered", ReplyAction= "http://CADEEternaService/IAnswerResult/QuestionAnsweredResponse")]
    string QuestionAnswered(string person_int, string course_int, string lesson_int);

    [System.ServiceModel.OperationContractAttribute(Action= "http://CADEEternaService/IAnswerResult/QuestionAnswered", ReplyAction= "http://CADEEternaService/IAnswerResult/QuestionAnsweredResponse")]
    System.Threading.Tasks.Task<string> QuestionAnsweredAsync(string person_int, string course_int, string lesson_int);
}

[System.ServiceModel.ServiceContractAttribute（命名空间=”http://CADEEternaService，ConfigurationName=“IAnswerResult”）]
公共接口IAnswerResult
{

System.Threading.Tasks.Task QuestionAnsweredAsync（字符串人物、字符串课程、字符串课程）；
}

在客户端的app.config中：

  <endpoint address="http://localhost:6255/CalculatorService" binding="basicHttpBinding"
      bindingConfiguration="BasicHttpBinding_IAnswerResult" contract="CADEEternaService.IAnswerResult"
      name="BasicHttpBinding_IAnswerResult" />
  <endpoint address="net.tcp://localhost:6256/CalculatorService"
      binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IAnswerResult"
      contract="CADEEternaService.IAnswerResult" name="NetTcpBinding_IAnswerResult">

但它仍然将“cadeeternaneservice.IAnswerResult”标记为一个错误，我也得到了原始错误，“找不到引用契约‘IAnswerResult’的默认端点元素…”。。。但是，我觉得奇怪的是，它在错误消息中对IAnswerResult而不是CadeternanService.IAnswerResult发出吠声。

在客户端的配置中，契约需要是完全限定的名称，而不仅仅是接口名称

<endpoint address="http://localhost:6255/CalculatorService" 
          binding="basicHttpBinding"
          bindingConfiguration="BasicHttpBinding_IAnswerResult" 
          contract="EternaService.IAnswerResult"
          name="BasicHttpBinding_IAnswerResult" />
  <endpoint address="net.tcp://localhost:6256/CalculatorService"
            binding="netTcpBinding" 
            bindingConfiguration="NetTcpBinding_IAnswerResult"
            contract="EternaService.IAnswerResult"
            name="NetTcpBinding_IAnswerResult">

换句话说，

eternaservice.IAnswerResult

，而不仅仅是

IAnswerResult

您需要在合同之前添加生成的服务引用的名称空间。。。。 contract=“xxxxxxx.IAnswerResult

 <system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_IAnswerResult" />
  </basicHttpBinding>
  <netTcpBinding>
    <binding name="NetTcpBinding_IAnswerResult" />
  </netTcpBinding>
</bindings>
<client>
  <endpoint address="http://localhost:6255/CalculatorService" binding="basicHttpBinding"
      bindingConfiguration="BasicHttpBinding_IAnswerResult" contract="**xxxxx.IAnswerResult**"
      name="BasicHttpBinding_IAnswerResult" />
  <endpoint address="net.tcp://localhost:6256/CalculatorService"
      binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IAnswerResult"
      contract="IAnswerResult" name="NetTcpBinding_IAnswerResult">
    <identity>
      <servicePrincipalName value="host/Server2012" />
    </identity>
  </endpoint>
</client>

我将两个协定值都更改为“EternaService.IAnswerResult”，但它给出了相同的错误，“在ServiceModel客户端配置部分中找不到引用协定“IAnswerResult”的默认端点元素。”。这可能是因为找不到应用程序的配置文件，或者在客户端元素中找不到与此约定匹配的端点元素。“我尝试使用InEllisSense，但它找不到我能识别的内容。请注意，您在

ServiceContract

上设置的命名空间与该合约的命名空间没有任何关系。服务契约名称空间是SOAP的一部分。正如我前面所说的，完全限定的名称仍然会给出一个错误。在查看app.config时，如果我将鼠标悬停在协定值上，它会说“根据其数据类型'clientContractType'-枚举约束失败，协定值无效”尝试将命名空间更改为不在项目命名空间EternaService{[ServiceContract（命名空间="你的命名空间与你的服务名称相同。我以为你找到了什么…除非我把更改搞砸了。我使用CadeterNaService作为合同命名空间编辑了原始帖子。在客户端应用中，你需要从Windows服务添加对WCF服务库项目的引用，并将以下using语句添加到他在Windows服务项目中创建了**.cs文件。请尝试按照本教程进行操作。关键是客户端中对WCF服务的引用。奇怪的是，我创建了ServiceReference ok，但无法使用“using”来显示它.因此，我完全限定了它：CalculatorServiceReference.AnswerResultClient客户端=新的CalculatorServiceReference.AnswerResultClient（“NetTcpBinding_IAnswerResult”）；
