当我使用iis将mvc应用程序部署到实时服务器时,为什么会出现错误“HRESULT异常:0x800A03EC”?

问题描述 投票:0回答:2

我正在上传一个excel文件,并尝试阅读其内容。使用以下代码,它在localhost上正常工作。但是,如果我使用IIS上传到实时服务器,它将无法正常工作。奇怪的是,我上传的文件确实保存到服务器上的内容文件夹,但是在错误消息中它看起来是从我的本地计算机打开文件:

Microsoft.Office.Interop.Excel.Workbooks.Open(String Filename,Object UpdateLinks,Object ReadOnly,Object Format,Object Password,Object WriteResPassword,Object IgnoreReadOnlyRecommended,Object Origin,Object Delimiter,Object Editable,Object Notify,Object Converter,Object AddToMru ,Object Local,Object CorruptLoad)+0 Twilio4.Controllers.HomeController.Import(HttpPostedFileBase excelfile,SendMessageVal Model)

在C:\ Users \ sbudhai \ source \ repos \ SAP \ SAP \ Controllers \ HomeController.cs:111

[HttpPost]
public ActionResult Import(HttpPostedFileBase excelfile, SendMessageVal Model)
{
    if(ModelState.IsValid == true)
    {
        if (excelfile == null || excelfile.ContentLength == 0)
        {
            ViewBag.Error2 = "Please select an excel file <br>";
            return View(Model);
        }
        else
        {
            if (excelfile.FileName.EndsWith("xlsx") || excelfile.FileName.EndsWith("xls"))
            {
                string path = Server.MapPath("~/Content/" + excelfile.FileName);
                if (System.IO.File.Exists(path))
                    System.IO.File.Delete(path);
                excelfile.SaveAs(path);

                //Read data from excel file 
                Excel.Application application = new Excel.Application();
                Excel.Workbook workbook = application.Workbooks.Open(path);
                Excel.Worksheet worksheet = workbook.ActiveSheet;
                Excel.Range range = worksheet.UsedRange;
                List<NUMBER> listProducts = new List<NUMBER>();
                var C = range.Rows.Count;
                var B = range.Rows.Count;

                C++;
                for (int row = 2; row < C; row++)
                {
                    NUMBER p = new NUMBER();
                    p.NUMBER1 = long.Parse(((Excel.Range)range.Cells[row, 1]).Text);
                    listProducts.Add(p);
                }

                ViewBag.ListProducts = listProducts;
                workbook.Close(path);
                return View("Confirm", listProducts);
            }
            else
            {
                ViewBag.Error = "File type is incorrect <br>";
                return View(Model);
            }

        }
    }
    else
    { 
        return View(Model);
    }
}

在服务器上使用Office Interop是not supported

链接的文章描述了您将面临的一些问题。我建议使用替代品,如EPPlus,或商业产品,如Aspose Cells

您可以使用OpenXML库而不是Office Interop,您将花时间尝试修复它,但最终会更好
