蝙蝠：我是使用asp.net mvc 4的新手.

我有一个动作,创建一个Excel文件,然后将其转换为PDF.

从视图

@Html.ActionLink("Generate Invoice","genInvoice",new { id = item.invoiceID }) |

行动：

public ActionResult genInvoice(int id = 0)
    {
        var invoiceItems = from k in db.InvoiceItems
                           where k.invoiceID == id
                           select k;

        string invoiceClient = (from kk in db.Invoices
                                where kk.invoiceID == id
                                select kk.clientName).Single();


        invoiceClient = invoiceClient + "_" + DateTime.Now.ToString("ddd dd MMM yyyy hhTmm");
        string websitePath = Request.PhysicalApplicationPath;
        string pathName = websitePath + "" + invoiceClient ;
        generateInvoice(invoiceItems,pathName + ".xlsx",id);
        convertToPDF(pathName,invoiceClient);

//Response.AppendHeader("Content-Disposition","attachment");

          var viewModel = new InvoiceItemAdd();
          viewModel.Invoices = db.Invoices
              .Include(i => i.InvoiceItems)
              .OrderBy(i => i.invoiceID);
        return View("Index",viewModel);
        //return RedirectToAction("Index",viewModel);


    }

现在我想最终下载PDF文件,然后返回到索引视图.
它进入索引视图打印html等,但然后窗口保持为白色屏幕与url：/ Invoice / genInvoice / 1

知道我怎么能这样做吗？ (生成PDF后返回索引视图,同时下载)

解决方法

对不起,我修复了白屏问题.在尝试进行PDF下载时

//Response.AppendHeader("Content-Disposition","inline; filename="+invoiceClient+".pdf");
            //Return File(output,"application/pdf");
            //Response.Flush();

            //Response.End();

Response.End()没有被注释掉,我想这就停止了.

现在的问题是如何在单独的选项卡中打开PDF并返回当前的索引
用上面的代码.

编辑：
决定文件可以下载.

public FileResult genInvoice(int id = 0)
{
//More code
Response.AppendHeader("Content-Disposition","attachment; filename="+pathName+".pdf");
return File(websitePath + "" + invoiceClient + ".pdf","application/pdf");
}
