C# Net Mvc：如何通过Ajax调用加载RDLC报告

我有一个控制器操作，它通过return File（）函数返回RDLC报告。通过浏览器地址栏调用此操作时，输出正常。同样，当通过ajaxget方法调用此操作时，成功数据将以字符串形式显示。我只想在新窗口中以PDF文件的形式显示ajax调用的输出。有办法吗？我不想将参数作为window.open（）函数的查询字符串发送，该函数用于从浏览器地址栏调用操作

success: function (data) { 
     var w = window.open();
     $(w.document.body).html(data);
     }

您必须使用此选项，而不是窗口。open（）使用此选项

您可以轻松地在此操作中放置代码

public ActionResult Download()

    {

        LocalReport localReport = new LocalReport();
        localReport.ReportPath = Server.MapPath("~/Reports/PatientRecipt.rdlc");
        ReportDataSource reportDataSource = new ReportDataSource();
        reportDataSource.Name = "DataSet1";
        //reportDataSource.Name = "PatientRecipt";
        reportDataSource.Value = applicationDbContext.TblInvoices.Select(x => x).ToList();
        localReport.DataSources.Add(reportDataSource);
        string reporttype = "PDF";
        string mimeType;
        string encoding; string[] streams;
        Warning[] warnings;
        byte[] renderedByte;
        renderedByte = localReport.Render(reporttype, "", out mimeType, out encoding, out reporttype, out streams, out warnings);

        Response.AddHeader("content-disposition", "attachment;filename = expens_report." + reporttype);

        return File(renderedByte, reporttype);

    }

不能使用ajax下载文件。请参阅使用重定向以获取返回文件的操作方法。您可以传递所有必需的参数，并在该操作方法内创建报告。@TetsuyaYamamoto我是这样做的，因为Stephen Muecke link说我想要的方法是不可能的。

public ActionResult Download()

    {

        LocalReport localReport = new LocalReport();
        localReport.ReportPath = Server.MapPath("~/Reports/PatientRecipt.rdlc");
        ReportDataSource reportDataSource = new ReportDataSource();
        reportDataSource.Name = "DataSet1";
        //reportDataSource.Name = "PatientRecipt";
        reportDataSource.Value = applicationDbContext.TblInvoices.Select(x => x).ToList();
        localReport.DataSources.Add(reportDataSource);
        string reporttype = "PDF";
        string mimeType;
        string encoding; string[] streams;
        Warning[] warnings;
        byte[] renderedByte;
        renderedByte = localReport.Render(reporttype, "", out mimeType, out encoding, out reporttype, out streams, out warnings);

        Response.AddHeader("content-disposition", "attachment;filename = expens_report." + reporttype);

        return File(renderedByte, reporttype);

    }
