Question

我需要生成每个伙伴的AR的pdf副本，为此我试图通过TempData将模型传递给另一个视图，但它总是返回null。

以下是我的代码。

public ActionResult GenerateARPDFs(string dateasof)
{
    dateasof = "03-31-17";
    var report = new ReportViewModel();
    report.AccountsReceivable = _bhelper.GetAccountsReceivable("", "", "", DateTime.Parse(dateasof)).
                                Where(w => !w.SOANum.Any(y => char.IsLetter(y)) ||
                                w.SOANum.Contains("SOA")).ToList<AccountsReceivable>();

    foreach (var partner in report.AccountsReceivable.Select(m => m.BP).Distinct())
    {
        TempData["MyModel"] = report;
        var actionResult = new ActionAsPdf("AccountsReceivableReport_PerPartner", new { employeecode = partner })
        {   
            PageSize = Rotativa.Options.Size.Letter,
            PageOrientation = Rotativa.Options.Orientation.Landscape,
            PageMargins = new Rotativa.Options.Margins(5, 5, 5, 5),
            MinimumFontSize = 12
        };
        var byteArray = actionResult.BuildPdf(ControllerContext);
        var fullPath = ConfigurationManager.AppSettings["ArPDF"].ToString() + @"\" + partner + ".pdf";
        var fileStream = new FileStream(fullPath, FileMode.CreateNew, FileAccess.ReadWrite);
        fileStream.Write(byteArray, 0, byteArray.Length);
        fileStream.Close();
    }
    TempData["SuccessMessage"] = "Generation successful!";
    return View();
}



public ActionResult AccountsReceivableReport_PerPartner(string employeecode)
{
    var report = (ReportViewModel)TempData["MyModel"];
    report.AccountsReceivable = filter by partner here////....;
    return View(report);
}

但是当它到达AccountsReceivableReport时，tempdata始终为null。我可以回想一下AccountReceivableReport（）上的SP，但这需要更长的时间。

将tempdata传递给ActionAsPdf是否存在问题？我正在使用rotativa btw。

当我插入断点时，TempData [“MyModel”]已成功填充结果，但当我到达AccountsReceivableReport_PerPartner()的方法时，它现在为空。

如果我尝试将其从ActionAsPdf更改为ViewAsPdf，则会在buildPdf部分返回错误

ASP.NET MVC中的TempData基本上是派生自的字典对象 TempDataDictionary。 TempData将作为后续HTTP请求保留与其他选项（ViewBag和ViewData）相反，这些选项只适用于当前的要求。 detail

尝试此会话：

public ActionResult AccountsReceivableReport_PerPartner(string employeecode)
{
    var report = Session["MyModel"] as ReportViewModel;
    return View(report);
}

似乎无法将模型传递给ActionAsPdf
