編程C＃代碼以創建SSRS數據驅動的訂閱

Question

我在SQL Reporting Service 2012標准版下有帶有參數的SSRS報告。 我喜歡導出到excel並作為電子郵件中的附件發送到其他收據，而收據來自某些SQL查詢，這意味着它是動態的。

數據驅動的訂閱可以做到這一點，但是我有SQL Server 2012 Standard Edition，它不支持數據驅動的訂閱，並且我不能升級，因此我正在尋找可以完成類似數據驅動的訂閱的任何代碼。

我發現此鏈接可以解決我的問題。 http://jaliyaudagedara.blogspot.com/2012/10/creating-data-driven-subscription.html

當我在Visual Studio 2015“類庫”項目下通過添加服務引用“ http：// mylocalserver：81 / reportserver / ReportService2010.asmx ”嘗試此代碼時，在此代碼行上出現錯誤。 ReportingService2010SoapClient rs = new ReportingService2010SoapClient（）;

有關錯誤的其他信息：在ServiceModel客戶端配置部分中找不到引用合同'ReportService2010.ReportingService2010Soap'的默認終結點元素。 這可能是因為找不到您的應用程序的配置文件，或者是因為在客戶端元素中找不到與該協定匹配的端點元素。

在花了足夠的時間使其可以與“類庫”項目一起使用之后，我決定通過添加Web服務引用來在Web Service項目下進行代碼。 最后經過反復試驗，我在Web服務項目下獲得了工作代碼。 下面的代碼在具有Sql Server 2012企業版的本地計算機上運行，​​但是它給我同樣的錯誤，表明在具有SQL Server 2012標准的公司服務器上，此版本的Reporting Services不支持“數據驅動的報表訂閱”。版。

您無需說明為什么需要數據驅動訂閱-常規的SSRS訂閱可以通過電子郵件將包含設置參數或默認參數的Excel報告發送給您。

據我所知，沒有任何第三方工具可以模擬“數據驅動”訂閱，但是有些用戶創建了自己的訂閱。

如果只想根據條件觸發訂閱，則可以使用SSIS作業運行查詢以確定是否發送並觸發訂閱。

類似於數據驅動訂閱SSRS Standard Edition 2008

如果您需要更復雜的內容（例如更改TO / CC收件人，更改參數值...），則需要進行一些編程。 這是從理論和代碼開始的幾件事：
