| 一般一個已經實現功能的WEB Server會發布自己的WSDL檔案，供用戶端組建代理程式類。 但有時是先有的server與client互動的介面定義（WSDL）檔案，然後由server和client端分別寫程式，一個提供web服務，一個使用web服務。 以下介紹如何由已有的WSDL檔案在VS2005中產生server端代碼。 1）使用VS2005提供的工具wsdl.exe由WSDL檔案產生cs檔案： 使用wsdl.exe的/serverInterface選項（或縮寫的 /si）指定輸入的wsdl檔案（注意，如果要轉換的wsdl檔案中import了其他wsdl檔案，則所有檔案都應列出，包括使用到的xsd檔案也應列出）。輸出將是 一個代碼檔案（預設是C#的，如果需要別的語言，參考MSDN中wsdl.exe的使用說明），其中包含每個 wsdl 綁定的介面。 樣本：假設ServerInterfaceSample.wsdl檔案中import了importedSample.wsdl，並使用Service.xsd作為schema檔案； wsdl.exe /si ServerInterfaceSample.wsdl importedSample.wsdl Service.xsd 產生代碼如下: //------------------------------------------------------------------------------

} 代碼中有一個介面類,並給出了介面函式宣告. 此功能的優點是將實現代碼和協定代碼（如介面所定義的那樣）分開。 如果更改 wsdl，然後重建介面，則不會丟失任何實現代碼。 若要遵循建議的設計指南，則不應將任何代碼放置在更改 wsdl 協定的實現中。 同樣，不應使用影響運行時行為的代碼來更改介面。 協定和實現的詳細資料應該分開。
2) 在VS IDE中建立一個web service工程,加入新產生的**Interface.cs檔案.
將自動產生的Service類改為從加入的Interface介面類派生,並實現所有的介面函數.(注意名空間一致) [WebService(Namespace = "http://www.csapi.org/cs/wsdl")]
