在http//上没有端点可以接受WCF中的消息

我正在尝试开发 webservice .在我的应用程序中，我需要无需任何引用即可连接到 webservice ，因此我使用以下代码:

I am trying to develop a webservice. In my application I need to connect to my webservice without any referencing, so I use this code:

static void Main(string[] args)
{            

    BasicHttpBinding binding = new BasicHttpBinding();
    EndpointAddress address = new EndpointAddress("http://confdemo.spadsystem.com/WcfServiceLibrary1.Service1.svc");
    ChannelFactory<IService1> factory = new ChannelFactory<IService1>(binding, address);
    IService1 channel = factory.CreateChannel();

    Console.WriteLine(channel.GetCategoryName(1));
    Console.ReadLine();
}

但是在这一行中 channel.GetCategoryName(1)我收到此错误:

But in this line channel.GetCategoryName(1) I get this error :

There was no endpoint listening at http://confdemo.spadsystem.com/WcfServiceLibrary1.Service1.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

这是我的服务网络配置:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <customErrors mode="Off"/>
    <compilation debug="true" />
  </system.web>
  <!-- When deploying the service library project, the content of the config file must be added to the host's 
  app.config file. System.Configuration does not support config files for libraries. -->
  <system.serviceModel>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true">
    </serviceHostingEnvironment>
    <services>
      <service name="WcfServiceLibrary1.Service1">
        <host>
          <baseAddresses>
            <add baseAddress = "http://localhost:8733/Design_Time_Addresses/WcfServiceLibrary1/Service1/" />
          </baseAddresses>
        </host>
        <!-- Service Endpoints -->
        <!-- Unless fully qualified, address is relative to base address supplied above -->
        <endpoint address="confdemo.spadsystem.com/WcfServiceLibrary1.Service1.svc" binding="basicHttpBinding" contract="WcfServiceLibrary1.IService1">
          <!-- 
              Upon deployment, the following identity element should be removed or replaced to reflect the 
              identity under which the deployed service runs.  If removed, WCF will infer an appropriate identity 
              automatically.
          -->
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <!-- Metadata Endpoints -->
        <!-- The Metadata Exchange endpoint is used by the service to describe itself to clients. --> 
        <!-- This endpoint does not use a secure binding and should be secured or removed before deployment -->
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- 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="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

</configuration>

注意:当我添加引用时，它会起作用，但是当我不添加引用时，它就不会起作用.

note:when I add the reference it works, it doesn't work when I don't add that to reference .
