导出报表CPU飙升问题

每次执行到这句的时候，程序占用CPU就会一直往上飙升

您好，你使用这种导出方式试试：
// Provide the page report you want to render.GrapeCity.ActiveReports.PageReport report = new GrapeCity.ActiveReports.PageReport();GrapeCity.ActiveReports.Document.PageDocument reportDocument = new GrapeCity.ActiveReports.Document.PageDocument(report);// Create an output directory.System.IO.DirectoryInfo outputDirectory = new System.IO.DirectoryInfo(@"C:\MyExcel");outputDirectory.Create();// 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;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.FileStreamProvider outputProvider = new GrapeCity.ActiveReports.Rendering.IO.FileStreamProvider(outputDirectory, System.IO.Path.GetFileNameWithoutExtension(outputDirectory.Name));// Overwrite output file if it already exists.outputProvider.OverwriteOutputFile = true;reportDocument.Render(excelRenderingExtension, outputProvider, excelSetting.GetSettings());

你好，刚试了你说的这种方式，结果是一样的没有什么区别，请求的时候CPU还是会往上升

你使用的是ActiveReports那个版本，然后你说的CPU上升，是在你的报表导出的过程中，上升，导出完成就下降是这样吗？
