Question

我在服务器上运行时遇到保存Excel电子表格的问题，在本地运行时，它运行得很漂亮！

有没有人曾经遇到过这个或者能指出我正确的方向？

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

G:\Development\MI Development\Technical     Development\MIPortal\MIPortal\Old_App_Code\ExportToExcel.cs:line 411

以下是我用来尝试保存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;
        }

更新了新错误：

Error creating excel application: Retrieving the COM class factory for component with
CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error:

   at MiFiveDayReport.ExportToExcel..ctor(String filepath) in G:\Development\MI Development\Technical Development\MIPortal\MIPortal\Old_App_Code\ExportToExcel.cs:line 94

在以下行中：

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;
        }
