如何使用这个类：
public class SSRSReportViewer
{
private ReportViewer _reportViewer;
//Display Report with NO parameters.
SSRSReport.DisplayReport(_reportViewer, ReportPath);
//Display Report WITH Parameters.
List<ReportParameter> paramList = new List<ReportParameter>();
paramList.Add(new ReportParameter("param1", param1);
paramList.Add(new ReportParameter("param2", param2);
SSRSReport.DisplayReport(_reportViewer, ReportPath ,paramList);
//Convert the Report to PDF Attachment.
//This Attachment object can be used along with SMTPClient
//object to send the report as a PDF attachment with an email.
Attachment att = SSRSReport.ConvertToPDFAttachment(this._reportViewer, fileName);
//Save Report with NO parameters already displayed on the reportViewer as PDF.
SSRSReport.SaveAsPDF(_reportViewer, filePath);
//Save Report with NO Parameters as PDF without displaying it in the ReportViewer.
SSRSReport.SaveAsPDF(_reportViewer, filePath, ReportPath);
//Save the Report WITH parameters as PDF.
SSRSReport.SaveAsPDF(_reportViewer, filePath, ReportPath, paramList);
}

我相信2005年之后的所有SSRS版本都有一个SOAP Web服务，可以访问并提供您所需的内容 . C＃应该能够读取它（或者如果你的代码更快，你可以渲染客户端） . GetDataSourceContents是要查找的元素 . Here's 2008年的文件 .
您可以在2008 here找到Microsoft的完整 endpoints 规范 . 应该有一个带有reportservice2008.asmx的目录（或者如果您认为this讨论，则为... 2006 for SharePoint） . Here's有关如何将服务引用添加到Visual Studio的文档 .
这是我觉得它可能适合你的一段代码
如何使用这个类：

已经说得好，更简单的方法是使用webservice：
案例1：您要列出所有报告
使用"CatalogItem()"服务
以任何你想要的方式显示并让用户选择
案例2：您确切地知道要启动或用户选择哪个报告（通过单击元素）来显示一个
然后是简单的电话：
http://YOUR_REPORTING_SERVER_URL?/PATH_TO_SPECIFIC_REPORT/REPORT_NAME&rs:Command=Render&rs:Format=EXCEL&ADDITIONNAL_PARAMETER1=VALUE注意：rs：格式在这里配置为导出Excel（您也可以定义pdf等...） . 让报告服务为您完成工作 . 不想导出，跳过此参数可在导航资源管理器中打开报告服务 .
