Question

我正在尝试从库的app.config文件读取类库中的服务配置。但低于异常

找不到名称为'WSHttpBinding_IUsers'且合同为'ISGP.Plugins.SolveService.IUsers'的终结点元素在ServiceModel客户端配置部分。这可能是因为找不到您的应用程序的配置文件，或因为在客户端元素中找不到与该名称匹配的终结点元素。

我尝试执行以下代码来读取配置并创建客户端

 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;
    }


}

按以下方式调用此方法

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

但是它抛出上述异常，app.config文件如下所示

 <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>

请在通道工厂构造函数中传递端点参数。

ConfigurationChannelFactory channelFactory =新 ConfigurationChannelFactory（configName，配置，null）;

您可以参考以下代码。

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();
