如何使用WCF服务的代理实现读取类库中的System.serviceModel

Question

I am trying to read service configuration in Class Library from the app.config file of the library. but getting below exception

Could not find endpoint element with name 'WSHttpBinding_IUsers' and contract 'ISGP.Plugins.SolveService.IUsers' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element.

I tried ti implement the below code to read the config and create the client

 public class ServiceManager
{
    public static T CreateServiceClient<T>(string configName)
    {
       // string _assemblyLocation = Assembly.GetExecutingAssembly().Location;

        var configuration = ConfigurationManager.OpenMappedExeConfiguration(
                         new ExeConfigurationFileMap
                         {
                             ExeConfigFilename = "app.config"
                         }, ConfigurationUserLevel.None);

        ConfigurationChannelFactory<T> channelFactory = new ConfigurationChannelFactory<T>(configName, configuration, null);
        var client = channelFactory.CreateChannel();
        return client;
    }


}

Call this method as below

    usersClient= (UsersClient)ServiceManager.CreateServiceClient<IUsersChannel>("WSHttpBinding_IUsers");
  usersClient.ClientCredentials.UserName.UserName = userName;
  usersClient.ClientCredentials.UserName.Password = password;

But it throws the above exception the app.config file is as below

 <system.serviceModel>
  <bindings>
    <wsHttpBinding>
      <binding name="WSHttpBinding_IUsers">
        <security mode="TransportWithMessageCredential">
          <transport clientCredentialType="None" />
          <message clientCredentialType="UserName" establishSecurityContext="false" />
        </security>
      </binding>
    </wsHttpBinding>
  </bindings>
  <client>
    <endpoint address="https://xxxxxx16.prod.xxxxx.local/WebServices/v3/Users.svc"
        binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IUsers"
        contract="ISGP.Plugins.SolveService.IUsers" name="WSHttpBinding_IUsers" />
  </client>
</system.serviceModel>

Please pass the endpoint parameter in the channel factory constructor.

ConfigurationChannelFactory channelFactory = new ConfigurationChannelFactory(configName, configuration, null);

You can refer to the following code.

ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
            fileMap.ExeConfigFilename = "app.config";
            Configuration newConfiguration = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
            ConfigurationChannelFactory<IService> factory = new ConfigurationChannelFactory<IService>("endpoint1", newConfiguration, new EndpointAddress("http://localhost:8000/servicemodelsamples/service"));
            factory.Credentials.UserName.UserName = "jack";
            factory.Credentials.UserName.Password = "123456";
            IService client1 = factory.CreateChannel();
