我在服务器上运行时保存 Excel 电子表格时遇到问题,在本地运行时,它运行良好!
有没有人遇到过这个问题或者可以指出我正确的方向?
应用程序池以“LocalSystem”身份运行。
谢谢!
我不断收到以下错误/堆栈跟踪:
Error saving the excel sheet:
Exception from HRESULT: 0x800A03EC at Microsoft.Office.Interop.Excel._Workbook.SaveAs(Object Filename, Object FileFormat,
Object Password, Object WriteResPassword, Object ReadOnlyRecommended, Object
CreateBackup, XlSaveAsAccessMode AccessMode, Object ConflictResolution, Object
AddToMru, Object TextCodepage, Object TextVisualLayout, Object Local)
at MiFiveDayReport.ExportToExcel.SaveAs(String filepath, XlFileFormat type) in
G:\Development\MI Development\Technical Development\MIPortal\MIPortal\Old_App_Code\ExportToExcel.cs:line 411
这是我用来尝试保存 excel 文档的代码:
try
{
if (log.IsInfoEnabled) log.Info("Saving...");
if (string.IsNullOrEmpty(filepath))
//Sets the filepath as the default
excelBook.SaveAs(this.filepath, type);
else
excelBook.SaveAs(filepath, type);
if (log.IsInfoEnabled) log.Info("Saved!");
success = true;
}
catch (Exception ex)
{
//SendEmail e = new SendEmail("Error saving excel sheet: " + ex.Message);
//SendEmail e1 = new SendEmail("Error saving excel sheet: " + ex.StackTrace);
if (log.IsErrorEnabled) log.Error("Error saving the excel sheet: "
+ ex.Message
+ ex.StackTrace);
throw;
}
更新的新错误:
Error creating excel application: Retrieving the COM class factory for component with

在以下行:
try
{
if (log.IsInfoEnabled) log.Info("Creating an excel application...");
excelApp = new Application();
if (log.IsInfoEnabled) log.Info("Excel application created");
}
catch (Exception ex)
{
if (log.IsErrorEnabled) log.Error("Error creating excel application: " + ex.Message + ex.StackTrace);
throw;
}
