方法1：通过数据库

（1）导出excel

CDatabase database;
CString sDriver     = _T("MICROSOFT EXCEL DRIVER (*.XLS)"); // Excel安装驱动
CString sExcelFile  =  _T("c:\\系统告警信息导出文件.xls");     // 要建立的Excel文件
if (_waccess(sExcelFile.AllocSysString(),0)!= -1)remove(sExcelFile);//删除TRY
{// 创建进行存取的字符串CString sSql;sSql.Format(_T("DRIVER={%s};DSN='''';FIRSTROWHASNAMES=1;READONLY=FALSE;CREATE_DB=\"%s\";DBQ=%s"),sDriver, sExcelFile, sExcelFile);// 创建数据库 (既Excel表格文件)if( database.OpenEx(sSql,CDatabase::noOdbcDialog) ){//  创建表结构(姓名、年龄)sSql = _T("CREATE TABLE 表名(编号 TEXT, 字段1TEXT, 字段2TEXT, 字段3TEXT, 字段4TEXT, 字段5TEXT,[字段6] TEXT)");database.ExecuteSQL(sSql);for( int iCount=0; iCount <m_list.GetItemCount();iCount++){CString  strNum,strMsi,strPhoneNum,strType,strResult,strDescribe,strTime;strNum     = m_list.GetItemText(iCount, 0);strMsi     = m_list.GetItemText(iCount, 1);strPhoneNum = m_list.GetItemText(iCount, 2);strType       = m_list.GetItemText(iCount, 3);strResult  = m_list.GetItemText(iCount, 4);strDescribe = m_list.GetItemText(iCount, 5);strTime       = m_list.GetItemText(iCount, 6);// 插入数值sSql.Format(_T("INSERT INTO 表名(编号, 字段1, 字段2, 字段3, 字段4, 字段5,\[字段6]) VALUES ('%s','%s','%s', '%s','%s','%s', '%s')"),strNum,strMsi,strPhoneNum, strType,strResult,strDescribe, strTime);database.ExecuteSQL(sSql);}}   // 关闭数据库database.Close();}CATCH_ALL(e){TRACE1("Excel驱动没有安装: %s",sDriver);MessageBox(_T( "导出数据失败!"), _T( "错误" ), MB_OK);}END_CATCH_ALL;

（2）导入excel

CString strFileFilter(_T("XLS File(*.xls)|*.xls|XLSX File(*.xlsx)|*.xlsx||"));CFileDialog fileOpen(TRUE, _T("*.xls;*.xlsx"), _T(""), OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT,strFileFilter , NULL);if (IDOK != fileOpen.DoModal())return ;CString sExcelFile = fileOpen.GetPathName();CString sSql;CString sDriver       = _T("MICROSOFT EXCEL DRIVER (*.XLS)");              // Excel安装驱动sSql.Format(_T("DRIVER={%s};DSN='''';FIRSTROWHASNAMES=1;READONLY=FALSE;CREATE_DB=\"%s\";DBQ=%s"),sDriver, sExcelFile, sExcelFile);CDatabase database;CRecordset rs;if( !database.OpenEx(sSql,CDatabase::noOdbcDialog) )return;m_list.DeleteAllItems();CRecordset recordset(&database);sSql = _T("select * from 白名单 ");recordset.Open(CRecordset::forwardOnly, sSql, CRecordset::readOnly);CString strPhoneNumber,strVender,strIMSI,strIMEI,strRollCall;    int nIndex = 0;while( !recordset.IsEOF( ) ) {recordset.GetFieldValue(short(0),strPhoneNumber);recordset.GetFieldValue(short(1),strVender);recordset.GetFieldValue(short(2),strIMSI);recordset.GetFieldValue(short(3),strIMEI);recordset.GetFieldValue(short(4),strRollCall);recordset.MoveNext();}

方法2：调用libxl动态库
