黑马程序员 将Access数据库里的数据导入Sql server数据库里

---------------------- Windows Phone 7手机开发、.Net培训、期待与您交流！ ----------------------  

 

前几天在黑马论坛上遇到一个网友求手机IP地址的数据，我便回复，网上如果找不到的话可以加我QQ，今晚下班回来，打开QQ给他传过去~结

果让他想不到，用不了，因为我在网下下的是Access的数据库，而他用的是Sql Server数据库，然后我就引用了前几天所学的知识~些了一小段

程序，把Access数据库里的数据导入到Sql Server，虽然代码不够简洁，但还是顺利的完成啦~哈哈，希望网友给予改善
