从 MVC 3 控制器将 JavaScript 注入 PDF

Question

在我的ASP.NET MVC3(Razor) 应用程序中，我正在为print utility 苦苦挣扎。我要auto print a PDF file which is converted from rdlc。

我使用以下代码将 rdlc 转换为 pdf：

        LocalReport localReport = new LocalReport();

        localReport.ReportPath = @"Reports/OP/Rdlc/ClinicInvoiceReceipt.rdlc";

        iClinicInvoiceReceipt = new RmtOPInvoice.ClinicInvoiceReceipt();
        DataTable dt = iClinicInvoiceReceipt.SelectReceiptDtlForPrint(1);

        ReportDataSource reportDataSource = new ReportDataSource();
        reportDataSource.Value = dt;
        reportDataSource.Name = "DataSet1";
        localReport.DataSources.Add(reportDataSource);

        string reportType = "PDF";
        string mimeType;
        string encoding;
        string fileNameExtension;

        string deviceInfo =
         @"<DeviceInfo>
            <OutputFormat>PDF</OutputFormat>
            <PageWidth>5.83in</PageWidth>
            <PageHeight>8.27in</PageHeight>
            <MarginTop>0in</MarginTop>
            <MarginLeft>0.in</MarginLeft>
            <MarginRight>0in</MarginRight>
            <MarginBottom>in</MarginBottom>
        </DeviceInfo>";
        Warning[] warnings;

        string[] streams;

        byte[] renderedBytes;

        renderedBytes = localReport.Render(
           reportType,
           deviceInfo,
           out mimeType,
           out encoding,
           out fileNameExtension,
           out streams,
           out warnings);

        return File(renderedBytes, "application/pdf");

我想在视图上显示这个同时想open the print dialog of pdf viewer automaticaly

我只是在这里将 javscript 转换为 pdf here。但是我对在我上面的代码中实现这一点感到困惑。如果有人经历过这个，请分享。这对我真的很有帮助。

我刚刚发现在 PHP 中完成了相同的场景。 Here.

Answer 1

也许我发现的这个答案很有帮助

1. 是 ASP.NET MVC
2. 直接流式传输 RDLC 响应

Answer 2

我使用iTextSharp实现了这一点

Here 是我做的示例项目。
