HRESULT：0x800A03EC - 创建Excel文件时，它适用于我的计算机问题

Question

我正在使用来自我的asp.net应用程序中的mssql服务器的数据创建Excel报告。这里是我的方法：

[WebMethod] 
public static string ExportToExcel(string sourcetype) 
{ 
    Microsoft.Office.Interop.Excel.Application oXL; 
    Microsoft.Office.Interop.Excel._Workbook oWB; 
    Microsoft.Office.Interop.Excel._Worksheet oSheet; 
    Microsoft.Office.Interop.Excel.Range oRng; 

    try 
    { 
     oXL = new Microsoft.Office.Interop.Excel.Application(); 
     oXL.Visible = false; 

     oWB = (Microsoft.Office.Interop.Excel._Workbook)(oXL.Workbooks.Add(Missing.Value)); 
     oSheet = (Microsoft.Office.Interop.Excel._Worksheet)oWB.ActiveSheet; 

     List<ExcelReport> dataToExport = APIClient.GetExcelReportData(Utility.getCurrentFilterId(), sourcetype); 

     oSheet.Cells[1, 1] = "Source"; 
     oSheet.Cells[1, 2] = "UserName"; 
     oSheet.Cells[1, 3] = "Name"; 
     oSheet.Cells[1, 4] = "Message"; 
     oSheet.Cells[1, 5] = "Title"; 
     //oSheet.Cells[1, 6] = "Date"; 

     int activeRow = 2; 

     for (int i = 0; i < dataToExport.Count; i++) 
     { 
      oSheet.Cells[activeRow, 1] = dataToExport[i].Source; 
      oSheet.Cells[activeRow, 2] = dataToExport[i].UserName; 
      oSheet.Cells[activeRow, 3] = dataToExport[i].Name; 
      oSheet.Cells[activeRow, 4] = dataToExport[i].Message; 
      oSheet.Cells[activeRow, 5] = dataToExport[i].MessageTitle; 
      //oSheet.Cells[activeRow, 6] = dataToExport[i].EntityDate; 

      activeRow++; 
     } 

     oSheet.get_Range("A1", "Z1").Font.Bold = true; 
     oSheet.get_Range("A1", "Z1").VerticalAlignment = Microsoft.Office.Interop.Excel.XlVAlign.xlVAlignCenter; 
     oRng = oSheet.get_Range("A1", "Z1"); 
     oRng.EntireColumn.AutoFit(); 
     oXL.Visible = false; 
     oXL.UserControl = false; 

     string strFile = "report" + System.DateTime.Now.Ticks.ToString() + ".xls"; 
     string strCurrentDir = HttpContext.Current.Server.MapPath(".") + "\\ExcelReports\\"; 
     oWB.SaveAs(strCurrentDir + strFile, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, null, null, false, 
      false, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlShared, false, false, null, null, null); 
     //oWB.SaveCopyAs(strCurrentDir + strFile); 
     oWB.Close(null, null, null); 
     oXL.Workbooks.Close(); 
     oXL.Quit(); 
     System.Runtime.InteropServices.Marshal.ReleaseComObject(oRng); 
     System.Runtime.InteropServices.Marshal.ReleaseComObject(oXL); 
     System.Runtime.InteropServices.Marshal.ReleaseComObject(oSheet); 
     System.Runtime.InteropServices.Marshal.ReleaseComObject(oWB); 
     oSheet = null; 
     oWB = null; 
     oXL = null; 
     GC.Collect(); // force final cleanup! 

     //errLabel.Text = "<A href=http://" + strMachineName + "/ExcelGen/" + strFile + ">Download Report</a>"; 
     //string result = "<a href=\"~/ExcelReports/" + strFile + ">Raporu İndir</a>"; 
     string result = "ExcelReports/" + strFile; 
     return result; 
    } 
    catch (Exception theException) 
    { 
     String errorMessage; 
     errorMessage = "Error: "; 
     errorMessage = String.Concat(errorMessage, theException.Message); 
     errorMessage = String.Concat(errorMessage, " Line: "); 
     errorMessage = String.Concat(errorMessage, theException.Source); 

     return errorMessage; 
    } 

} 

它工作正常，在我的机器，并在该应用程序发布到，当我在VS 2010，然后按F5打开源代码服务器。但是，如果我尝试通过IIS访问我的应用程序使用浏览器，我得到HRESULT：0x800A03EC错误。

我尝试下面的命令：

appcmd set config -section:asp -enableParentPaths:true 

我试着写权限授予我的文件夹中。

我试图从组件服务更改我的MS Excel应用程序设置。

但没办法！我无法得到它的工作。你有什么主意吗？我在配置中犯了错误吗？

由于提前，

Answer 1

我复制你的问题..尝试了所有：oWB.SaveAs/oWB._SaveAs/(oXL.ActiveSheet as Microsoft.Office.Interop.Excel.Worksheet).SaveAs/oWB.Application.ActiveWorkbook.SaveAs所有抛出异常：HRESULT：0x800A03EC ...

但我看到你试着用：OWB .SaveCopyAs（strCurrentDir + strFile）; 和它的作品，如果我下一个设置：

oWB.Saved = true; 
oWB.SaveCopyAs(strCurrentDir + strFile); 

为什么你不使用SaveCopyAs？

让像下面

C:\Windows\SysWOW64\config\systemprofile\Desktop 
C:\Windows\System32\config\systemprofile\Desktop
