1.使用XlsExport导出

以导出excel格式为例，XlsExport能够支持所有的报表类型

GrapeCity.ActiveReports.PageReport _reportDef = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(Server.MapPath("/Reports/" + report + ".rdlx")));            _reportDef.Report.DataSources[0].DataSourceReference = "";            _reportDef.Report.DataSources[0].ConnectionProperties.DataProvider = "OLEDB";            _reportDef.Report.DataSources[0].ConnectionProperties.ConnectString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};", Server.MapPath("/Data/NWind_CHS.mdb"));            GrapeCity.ActiveReports.Document.PageDocument _reportRuntime = new GrapeCity.ActiveReports.Document.PageDocument(_reportDef);                        GrapeCity.ActiveReports.Export.Excel.Section.XlsExport XlsExport1 = new GrapeCity.ActiveReports.Export.Excel.Section.XlsExport();            System.IO.MemoryStream ms = new System.IO.MemoryStream();            XlsExport1.FileFormat = GrapeCity.ActiveReports.Export.Excel.Section.FileFormat.Xlsx;            XlsExport1.Export(_reportRuntime, ms);            Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";            Response.AddHeader("content-disposition", Server.UrlPathEncode("attachment;filename=MyExport.xlsx"));            Response.BinaryWrite(ms.ToArray());            Response.End();

2.使用Render的方式导出

Render只能用来导出页面报表和RDL报表，但是对性能和样式都有很大的提升

GrapeCity.ActiveReports.PageReport _reportDef = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(Server.MapPath("/Reports/" + report + ".rdlx")));            _reportDef.Report.DataSources[0].DataSourceReference = "";            _reportDef.Report.DataSources[0].ConnectionProperties.DataProvider = "OLEDB";            _reportDef.Report.DataSources[0].ConnectionProperties.ConnectString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};", Server.MapPath("/Data/NWind_CHS.mdb"));            GrapeCity.ActiveReports.Document.PageDocument _reportRuntime = new GrapeCity.ActiveReports.Document.PageDocument(_reportDef);            // Create an output directory            System.IO.MemoryStream ms = new System.IO.MemoryStream();            // Provide settings for your rendering output.            GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtensionSettings            excelSetting = new GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtensionSettings();            excelSetting.FileFormat = GrapeCity.ActiveReports.Export.Excel.Page.FileFormat.Xls;            //excelSetting.MultiSheet = false;            GrapeCity.ActiveReports.Extensibility.Rendering.ISettings setting = excelSetting;            //Set the rendering extension and render the report.            GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtension            excelRenderingExtension = new            GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtension();            GrapeCity.ActiveReports.Rendering.IO.MemoryStreamProvider outputProvider = new GrapeCity.ActiveReports.Rendering.IO.MemoryStreamProvider();            _reportRuntime.Render(excelRenderingExtension, outputProvider, excelSetting.GetSettings());            Response.ContentType = "application/vnd.ms-excel";            Response.AddHeader("content-disposition", "inline;filename=MyExport.xls");            outputProvider.GetPrimaryStream().OpenStream().CopyTo(ms);            Response.BinaryWrite(ms.ToArray());            Response.End();
