从HRESULT：0x800A03EC获取exception，同时在Excel工作簿中添加新工作表

同时在Excel工作簿中添加一个新工作表，我从HRESULTexception：0x800A03EC：

Microsoft.Office.Interop.Excel._Workbook m_objBook = null; object m_objOpt = "Test"; m_objBook = (Microsoft.Office.Interop.Excel._Workbook)(m_objBooks.Add(m_objOpt)); m_objSheets = (Microsoft.Office.Interop.Excel.Sheets)m_objBook.Worksheets; m_objSheet1 = (Microsoft.Office.Interop.Excel._Worksheet)(m_objSheets.get_Item(1)); m_objSheet1.Name = "Project List"; m_objSheet2 = (Microsoft.Office.Interop.Excel._Worksheet)(m_objSheets.get_Item(2)) m_objSheet2.Name = "Project Status"; m_objSheet3 = (Microsoft.Office.Interop.Excel._Worksheet)(m_objSheets.get_Item(3)); m_objSheet3.Name = "Pending items"; 

在下面一行我得到错误 – exception来自HRESULT：0x800A03EC

  m_objSheet4 = (Microsoft.Office.Interop.Excel._Worksheet)(m_objSheets.Add (m_objOpt, m_objSheet3, 1, m_objOpt)); m_objSheet4 = (Microsoft.Office.Interop.Excel._Worksheet)(m_objSheets.get_Item(4)); m_objSheet4.Name = "NewSheet";
