带有使用ASP.NET MVC C＃生成的SQL存储过程的子报表的晶体报表

Question

我已经在Visual Studio 2019中使用存储过程创建了Crystal Report，该报告具有多个子报表和一个参数。我可以从报告中预览它。现在，我想预览它或使用ASP.NET MVC C＃生成PDF。但是我找不到办法。谁能帮忙？

Answer 1

伙计们，我对此进行了进一步研究，并找到了解决方案。它完美地工作而无需创建数据表。干杯。

public ActionResult DownloadPortfolio()
    {
        if (Session["user"] == null)
        {
            return RedirectToAction("Login", "Users");
        }
        User user = (User)Session["user"];

        ReportDocument rd = new ReportDocument();
        rd.Load(Path.Combine(Server.MapPath("~/Reports"), "InvestorPortfolio.rpt"));
        rd.SetDatabaseLogon(DbKeyManager.DbUser, DbKeyManager.DbPass, DbKeyManager.DbSource, DbKeyManager.DbName);
        rd.SetParameterValue("@investorcode", user.InvestorCode);

        Response.Buffer = false;
        Response.ClearContent();
        Response.ClearHeaders();


        rd.PrintOptions.PaperOrientation = CrystalDecisions.Shared.PaperOrientation.Portrait;
        rd.PrintOptions.ApplyPageMargins(new CrystalDecisions.Shared.PageMargins(5, 5, 5, 5));
        rd.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.PaperA4;

        Stream stream = rd.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
        stream.Seek(0, SeekOrigin.Begin);

        return File(stream, "application/pdf", user.InvestorCode+"Portfolio-Statement.pdf");
    }

您可以尝试生成pdf报告。

List<data> Data = //Data From stored procedure  
 rpt_Portfolio_finance rpt = new rpt_Portfolio_finance();
        rpt.Load();
        rpt.SetDataSource(Data);
        Stream s = rpt.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
        return File(s, "application/pdf");
