我想在 Visual Studio 2010 高级版中将一些数据写入 excel 文件，但是当我运行我的代码时，出现此错误：
comexception was unhandled by user code
Exception from HRESULT: 0x800A03EC
我在详细视图中的错误：
System.Runtime.InteropServices.COMException was unhandled by user code
Message=Exception from HRESULT: 0x800A03EC
Source=Microsoft.Office.Interop.Excel
ErrorCode=-2146827284

我使用 microsoft office 2013，我有参考资料：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;
using Microsoft.Office.Interop.Excel;
最后我在以下代码部分中出现了这个错误：
workbook = excelObj.Workbooks.Open(HttpContext.Current.Server.MapPath("~/") + fileName, 0, false, Type.Missing, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", true, false, Type.Missing, true, 0, 0);
我的完整代码：
Microsoft.Office.Interop.Excel.Application excelObj = null;
Microsoft.Office.Interop.Excel.Workbook workbook = null;
excelObj = new Microsoft.Office.Interop.Excel.Application();
string fileName = "DBE_BAKIM_FORMU" + ".xlsx";
System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");
workbook = excelObj.Workbooks.Open(HttpContext.Current.Server.MapPath("~/") + fileName, 0, false, Type.Missing, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", true, false, Type.Missing, true, 0, 0);
Microsoft.Office.Interop.Excel.Sheets sheets = workbook.Worksheets;
Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)sheets.get_Item(1);
worksheet.Cells[6, 3] = c.TalepTarihi.ToString();
worksheet.Cells[7, 3] = c.TalepTuru;
worksheet.Cells[8, 3] = c.ModulAdi;
worksheet.Cells[9, 3] = c.EkranRaporAdi;
worksheet.Cells[10, 3] = c.VerilenSure;
worksheet.Cells[11, 4] = c.USER.UserName +" " +c.USER.UserSurname;
worksheet.Cells[12, 4] = Convert.ToInt64(c.USER.UserTel);
workbook.Save();
excelObj.Workbooks.Close();
excelObj.Application.Quit();
提前谢谢..为什么我会犯这个错误？请帮忙..
