背景：

在普通的C#项目中，可以直接调用 WCF / Webservice；

在微软BI的 ssis中，有 webservice任务组件，也可以直接调用简单的 WCF / Webservice;

偶这边的情况是，后端的 WCF中用的反射，所以在 ssis中的webservice任务组件中，死活不能识别 WCF对应的方法。

所以只能在ssis的 script task组件中，用纯代码的方式来调用WCF服务。


就这样，可能还是有问题；可能会碰到 不能识别 System.ServiceModel节点的错误。根本原因在于 微软的ssis的script task组件中，它不能识别 WCF/ webservice的 app.config文件。


解决方法：除了添加服务引用外，还需要在代码中设置所有的属性，包括 URL


参考代码：

//HttpsTransportBindingElement httpsTransport = new HttpsTransportBindingElement();
            HttpTransportBindingElement httpsTransport = new HttpTransportBindingElement();
            httpsTransport.ManualAddressing = false;
            httpsTransport.MaxBufferPoolSize = 524288;
            httpsTransport.MaxReceivedMessageSize = 65536;
            httpsTransport.AllowCookies = false;
            httpsTransport.AuthenticationScheme = System.Net.AuthenticationSchemes.Anonymous;
            httpsTransport.BypassProxyOnLocal = false;
            httpsTransport.DecompressionEnabled = true;
            httpsTransport.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
            httpsTransport.KeepAliveEnabled = true;
            httpsTransport.MaxBufferSize = 65536;
            httpsTransport.ProxyAuthenticationScheme = System.Net.AuthenticationSchemes.Anonymous;
            httpsTransport.Realm = "";
            httpsTransport.TransferMode = TransferMode.Buffered;
            httpsTransport.UnsafeConnectionNtlmAuthentication = false;
            httpsTransport.UseDefaultWebProxy = true;
            //httpsTransport.RequireClientCertificate = false;


            TextMessageEncodingBindingElement encoding = new TextMessageEncodingBindingElement();
            encoding.MessageVersion = MessageVersion.Soap11;
            encoding.WriteEncoding = Encoding.UTF8;
            encoding.MaxReadPoolSize = 64;
            encoding.MaxWritePoolSize = 16;
            encoding.ReaderQuotas.MaxDepth = 32;
            encoding.ReaderQuotas.MaxStringContentLength = 8192;
            encoding.ReaderQuotas.MaxArrayLength = 16384;
            encoding.ReaderQuotas.MaxBytesPerRead = 4096;
            encoding.ReaderQuotas.MaxNameTableCharCount = 16384;

            CustomBinding binding = new CustomBinding();
            binding.Name = "GetData";
            binding.Elements.Add(encoding);
            binding.Elements.Add(httpsTransport);

            EndpointAddress endPoint = new EndpointAddress("http://192.168.4.16:83/Service1.svc");

            TestServiceRef.Service1Client svc = new TestServiceRef.Service1Client(binding, endPoint);
            string sResult= svc.GetData(89);


结果：

微软 BI ssis 中的 script task中用代码直接调用 WCF / Webservice_c#
