範例

下列程式碼範例會示範如何使用 MessageContractAttribute 控制要求訊息和回應訊息的 SOAP 封套結構,並說明如何使用 MessageHeaderAttribute 建立回應訊息的 SOAP 標頭和使用 MessageBodyMemberAttribute 指定要求訊息和回應訊息的本文。The following code example shows the use of the MessageContractAttribute to control the SOAP envelope structure for both the request message and the response message, and the use of both the MessageHeaderAttribute (to create a SOAP header for the response message) and the MessageBodyMemberAttribute (to specify the bodies of both the request and response message). 這個程式碼範例包含每個所傳送訊息的範例。The code example contains an example of each message when sent.
