编程c#代码以创建SSRS数据驱动订阅

我在SQL Reporting service 2012标准版下有带参数的SSRS报告。我喜欢导出到excel,并在电子邮件中作为附件发送到不同的收据,收据来自一些SQL查询,这意味着它是动态的。

数据驱动订阅可以做到这一点,但我有SQL Server 2012标准版,它不支持数据驱动订阅,我不能升级,所以我正在寻找任何代码,可以做类似的工作,如数据驱动订阅。

我发现这个链接解决了我的问题。 http://jaliyaudagedara.blogspot.com/2012/10/creating-data-driven-subscription.html

当我在visual studio 2015“类库”项目下通过添加服务引用来尝试这段代码时 http://mylocalserver:81/reportserver/ReportService2010.asmx “我在这行代码中遇到了一个错误。 ReportingService2010SoapClient rs=新的ReportingService2010SoapClient();

有关错误的其他信息:找不到引用合同“ReportService2010”的默认端点元素。ServiceModel客户端配置部分中的ReportingService2010Soap。这可能是因为找不到应用程序的配置文件,或者在客户端元素中找不到与此约定匹配的端点元素。

在花了足够的时间使它与“类库”项目一起工作之后,我决定通过添加web服务引用来完成web服务项目下的代码。经过一些尝试和错误,我终于在web服务项目下获得了工作代码。下面的代码在我的本地机器上运行,该机器有Sql server 2012 enterprise edition,但它给了我同样的错误,即在我的公司服务器上(该服务器有Sql server 2012 standard edition),此版本的Reporting Services不支持“数据驱动的报表订阅”。
