Question

我一直在寻找在ASP.Net MVC中进行报告的解决方案，我确实遇到了Rai Kaimal Rendering an RDLC directly to the Response stream in ASP.NET MVC的解决方案。一切正常，但localReport.Render（）函数需要很长时间来呈现页面（2个非常简单的页面需要40秒 - 相同的报告在2秒内从winforms解决方案执行）。任何帮助，将不胜感激。如果没有办法加速报告，我很想知道其他开发人员如何在ASP.Net MVC解决方案中处理报告。

这是我的代码：

    public ActionResult CustomerReport()
    {
        var localReport = new LocalReport
                              {
                                  ReportPath = Server.MapPath("~/Reports/CustomerReport.rdlc")
                              };
        var reportDataSource = new ReportDataSource("Customers", _repository.GetAll( ));

        localReport.DataSources.Add(reportDataSource);

        const string reportType = "PDF";

        string mimeType;
        string encoding;
        string fileNameExtension;

        //The DeviceInfo settings should be changed based on the reportType

        //http://msdn2.microsoft.com/en-us/library/ms155397.aspx

        const string deviceInfo = "<DeviceInfo>" +
                                  "  <OutputFormat>PDF</OutputFormat>" +
                                  "  <PageWidth>8.5in</PageWidth>" +
                                  "  <PageHeight>11in</PageHeight>" +
                                  "  <MarginTop>0.5in</MarginTop>" +
                                  "  <MarginLeft>1in</MarginLeft>" +
                                  "  <MarginRight>1in</MarginRight>" +
                                  "  <MarginBottom>0.5in</MarginBottom>" +
                                  "</DeviceInfo>";

        Warning[] warnings;
        string[] streams;

        //Render the report
        byte[] renderedBytes = localReport.Render(
            reportType,
            deviceInfo,
            out mimeType,
            out encoding,
            out fileNameExtension,
            out streams,
            out warnings);

        return File(renderedBytes, mimeType);
    }

在<trust legacyCasModel="true" level="Full"/> <system.web>内的web.config标记内放置# Adding a command to launch an application if x[0] ['alternatives'] [0] ['transcript'] == 'run ' and Command_State is 'Started': print("Running...") Command_State = 'Run' self.listening = True为我做了。我在ASP.NET Webforms中。 More details here
