我有一个用 C# 编写的网络应用程序，我需要能够在 aspx 页面上呈现SSRS 报告而不使用报告查看器控件。
因为 div 标签内的 HTML 将是完美的。我通过ReportingService2010 引用将应用程序附加到我的SSRS 实例。
我在网上找到了一些示例，但适用于ReportingServices2005，无法将它们移植过来。
我该怎么做？

这是我从大约一年前完成的一个项目中提取出来的。
几个关键点：
它使用 ReportExecutionService 引用，您将不得不使用它，但具体细节应该都在这里。
我真的很想花时间清理一下，但我没有时间抱歉，我希望它有所帮助

执行：
第一个参数是报告在服务器上的位置。 第二个是 SSRSExportType 枚举
RenderReport("ReportPathOnServer",SSRSExportType.HTML);
【讨论】：
如果您只是想显示报表的 HTML 渲染，并且希望它看起来像应用程序的原生对象，没有任何参数或工具栏，那么您可以直接调用报表的 URL 并包含 "&rc: URL 中的 Toolbar=false”。这将隐藏报表查看器控件的工具栏。此方法在URL Access Parameter Reference msdn article 下进行了描述。不完全是你要求的，但它可能达到目的。
如果您将结果嵌入到现有的 HTML 文档中，下面是一个省略 HTML 和 Body 部分的示例调用：
http://ServerName/ReportServer?%2fSome+Folder%2fSome+Report+Name&rs:Command=Render&rc:Toolbar=false&rc:HTMLFragment=true
【讨论】：
绝对是一个老问题，但如果您使用的是 ASP.NET MVC，您可以尝试this open source solution。它使用 HTML 帮助程序并在 iframe 中呈现 .aspx 页面。该 repo 有一个服务器端、本地渲染和匿名示例。
