Question

我正在创建一个WCF服务，它似乎在昨天的VS测试客户端上正常运行但今天它似乎在我尝试更改web.config文件后抛出此错误。

下面是代码和配置文件：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;

namespace TSService
{
    interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface ITSService

    [OperationContract]
    List<Sel_Test> RunScript(List<SName> SNamesToRun, int LogPathIndex, RunEnvironment EnvironmentName, BOptions BType, NavOption NavEnum);

}

 [DataContract]
    public class STest
    {
        [DataMember]
        public ScriptName SName { get; set; }
        [DataMember]
        public BOptions BTypeUsed { get; set; }
        [DataMember]
        public int SResult { get; set; }
    }

    [DataContract(Name= "SName")]
    public enum SName
    {
        [EnumMember]
        PXXXX1,
        [EnumMember]
        PXXXX2,
        [EnumMember]
        PXXXX3,
        [EnumMember]
        PXXXX4

    }

    [DataContract]
    public enum NavOption 
    {
        [EnumMember]
        ContinueToNext,
        [EnumMember]
        Skip,
        [EnumMember]
        SignIn,
        [EnumMember]
        Registration
    }

    [DataContract]
    public enum BOptions
    { 
        [EnumMember]
        FAA1,
        [EnumMember]
        ReFi,
        [EnumMember]
        RIE
    }

    [DataContract]
    public enum RunEnvironment 
    {
        [EnumMember]
        D,
        [EnumMember]
        Q,
        [EnumMember]
        S,
        [EnumMember]
        P
    }
    [DataContract]
    public enum PType 
    {
        [EnumMember]
        MAPD,
        [EnumMember]
        PDP,
        [EnumMember]
        MA,
        [EnumMember]
        Mgap
    };
}

在配置文件中我有：

<system.serviceModel>

    <behaviors>
      <serviceBehaviors>
        <behavior name="TSServiceBehavior">
          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>

    <services>
      <service name="TSService.ITSService" behaviorConfiguration="TSServiceBehavior">
        <endpoint address=""
                  binding ="basicHttpBinding"
                  contract="TSService.ITSService" />

        <endpoint address="mex"
                  binding="mexHttpsBinding"
                  contract="IMetadataExchange" />
      </service>
    </services>


    <bindings>
      <basicHttpBinding>
        <binding name ="TSServiceBinding" receiveTimeout="00:20:00" sendTimeout="00:20:00">
          <security mode="None"/>
        </binding>
      </basicHttpBinding>
    </bindings>


    <!--<protocolMapping>
      <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>-->
    <serviceHostingEnvironment aspNetCompatibilityEnabled="False" multipleSiteBindingsEnabled="true"/>
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <!--
        To browse web app root directory during debugging, set the value below to true.
        Set to false before deployment to avoid disclosing web app folder information.
      -->
    <directoryBrowse enabled="true"/>
  </system.webServer>



  <system.diagnostics>
    <sources>
      <source name="System.ServiceModel"
              switchValue="Information, ActivityTracing"
              propagateActivity="true">
        <listeners>
          <add name="traceListener"
              type="System.Diagnostics.XmlWriterTraceListener"
              initializeData= "c:\log\Traces.svclog" />
        </listeners>
      </source>
    </sources>
  </system.diagnostics>

在SVC标记中我有：

<%@ ServiceHost Language="C#" Debug="true" Service="TSService.ITSService" CodeBehind="TSService.svc.cs" %>

运行VS WCFTest客户端时出现的错误：

根据评论将其标记为已回答 - “我通过在标记中将ITSService更改为TSSErvice来消除此错误。”

ServiceHost仅支持类服务类型
