범용 반사를 사용하여 런타임 시 동적으로 WCF 클라이언트 만들기

만약에 우리가 WCF 서비스의 URL,binding,contractType을 알고 있다면 우리는 아래의 코드를 사용하여 WCF 클라이언트 대상을 만들 수 있습니다.

ChannelFactory<ITaskService>.CreateChannel(new BasicHttpBinding(),new EndpointAddress(url));

그러나 위의 코드에서 우리는 BasicHttpBinding의 설정 가능한 설정을 할 수 없다. 이때 우리는 아래의 코드를 사용하여 App.와 협조할 수 있다.Config 를 통해 Binding 정보를 구성할 수 있습니다.

ChannelFactory<ITaskService>.CreateChannel(new BasicHttpBinding("BasicHttpBinding_TaskService"),new EndpointAddress(url));

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_TaskService" closeTimeout="00:01:00"
                        openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
                        allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
                        maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
                        messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
                        useDefaultWebProxy="true">
          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                             maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"
                                  realm="" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
  </system.serviceModel>
</configuration>

그러나 상기 방법은 모두 정태적으로 완성된 것이다. 우리는 동태적으로 WCF 클라이언트 대상을 만드는 것을 실현할 방법이 있습니까?

    var service1 = GetWcfClient(url, new BasicHttpBinding(), typeof(ITaskService)) as ITaskService;
    var service2 = GetWcfClient(url, new BasicHttpBinding("BasicHttpBinding_TaskService"), typeof(ITaskService)) as ITaskService;

    public static object GetWcfClient(string url, Binding binding, Type contractType)
    {
        Type channelFactoryGenericType = typeof(ChannelFactory<>).MakeGenericType(new Type[] { contractType });
        MethodInfo method = channelFactoryGenericType.GetMethod("CreateChannel", new Type[] { typeof(Binding), typeof(EndpointAddress) });
        return method.Invoke(null, new Object[] { binding, new EndpointAddress(url) });
    }

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_TaskService" closeTimeout="00:01:00"
                        openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
                        allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
                        maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
                        messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
                        useDefaultWebProxy="true">
          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                             maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"
                                  realm="" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
  </system.serviceModel>
</configuration>
