对 C# 代码进行编程以创建 SSRS 数据驱动订阅

Question

我在 SQL 报告服务 2012 标准版下有带有参数的 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，并且收据来自一些 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，但我有不支持数据驱动订阅的SQL Server 2012标准版，我无法升级，所以我正在寻找任何可以像数据驱动订阅一样做类似工作的代码。

我找到了这个链接，它有我的问题的解决方案。 http://jaliyaudagedara.blogspot.com/2012/10/creating-data-driven-subscription.html

当我通过添加服务引用"http://mylocalserver:81/reportserver/ReportService2010.asmx"在Visual Studio 2015"类库"项目下尝试此代码时，我在此代码行上收到错误。 ReportingService2010SoapClient rs= new ReportingService2010SoapClient((;

有关错误的其他信息：在 ServiceModel 客户端配置部分找不到引用协定"ReportService2010.ReportingService2010Soap"的默认终结点元素。这可能是因为找不到应用程序的配置文件，或者因为在客户端元素中找不到与此协定匹配的终结点元素。

在花费足够的时间使其与"类库"项目一起使用后，我决定通过添加 Web 服务引用来执行 Web 服务项目下的代码。 经过一些反复试验，最后，我在Web服务项目下获得了工作代码。 下面的代码适用于我的本地计算机，该计算机具有Sql Server 2012企业版，但它给了我相同的错误，指出"数据驱动的报表订阅"在此不受支持报告服务版本"在我的公司服务器上，该服务器具有SQL Server 2012标准版。

你没有说明为什么需要数据驱动订阅 - 常规 SSRS 订阅可以通过电子邮件发送包含设置或默认参数的 Excel 报表。

据我所知，没有任何第三方工具可以模拟数据驱动订阅，但有一些用户创建了自己的工具。

如果只想根据条件触发订阅，则只需使用 SSIS 作业运行查询以确定是否发送，如果发送，则触发订阅。

类似于数据驱动订阅 SSRS 标准版 2008

如果您需要更复杂的东西(例如更改 TO/CC 收件人、更改参数值...(，则需要进行更多编程。以下是理论和代码入门的几件事：
