從服務導向解決方案使用管線
客戶服務協調流程的內嵌版本 (CustomerService) 直接呼叫付款追蹤系統。 為了準備已傳送訊息和處理已接收訊息，協調流程會從程式碼呼叫管線。 這可從其他實例版本重複使用管線。 它也維持從管線階段減少協調流程。
呼叫管線
若要從程式碼使用管線，您必須建立訊息集合、將要處理的訊息新增到集合、建立空的訊息以接收結果訊息，以及叫用管線。
CustomerService 協調流程中的下列程式碼位於ConstructRequestMessageAfterSendPipeline圖形中：
// Create the collection of messages to be sent to the send pipeline...
sendPipelineInputMessages =
new Microsoft.XLANGs.Pipeline.SendPipelineInputMessages();
sendPipelineInputMessages.Add(LastPaymentRequest);
// Create an empty message for the output from the pipeline...
LastPaymentRequestAfterSendPipeline = null;
// Execute the send pipeline and get the message output from
// the send pipeline.
Microsoft.XLANGs.Pipeline.XLANGPipelineManager.
ExecuteSendPipeline(
typeof(
Microsoft.Samples.BizTalk.
WoodgroveBank.PaymentTrackerPipelines.
PaymentTrackerSendPipeline
),
sendPipelineInputMessages,
LastPaymentRequestAfterSendPipeline
);
GetLastPaymentResponse圖形會從上述程式碼取得訊息、將它傳送至付款追蹤系統，並透過接收管線處理傳回的訊息：
// Execute the inline method to send the message to the
// Payment Tracking System and get the response.
// The response message received should be passed through the
// receive pipeline.
LastPaymentResponseBeforeReceivePipeline =
Microsoft.Samples.BizTalk.
WoodgroveBank.
PaymentTrackerCall.
PaymentTrackerCaller.
GetPaymeTrackerResponse
(
LastPaymentRequestAfterSendPipeline
);
// Execute the receive pipeline using the helper class so that we don't
// need to declare the non-serializable types involved.
// Set the documentspec name so the xml disassembler in the
// pipeline can resolve the schemas for the received message
// without ambiguity.
LastPaymentResponseBeforeReceivePipeline(XMLNORM.DocumentSpecName) =
"Microsoft.Samples.BizTalk.WoodgroveBank.Schemas.LastPaymentResponse, Microsoft.Samples.BizTalk.WoodgroveBank.Schemas, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5f57a322d27bc5fb";
// Create an empty response message and fill it in with the
// real response from the Payment Tracking System
LastPaymentResponse = null;
Microsoft.Samples.BizTalk.WoodgroveBank.Utilities.
ReceivePipelineHelper.CallReceivePipeLine (
typeof(
Microsoft.Samples.BizTalk.WoodgroveBank.
PaymentTrackerPipelines.PaymentTrackerReceivePipeline
),
LastPaymentResponseBeforeReceivePipeline,
LastPaymentResponse
);
