近日自己做了一个asp.net的网站,想找个空间弄上去看看,http://vwdhosting.net在上面注册了一个空间,传上去之后就出现这个问题,几乎每个页面都出现了,但是在本机运行的时候完全正常,有些页面能读取出数据,但只要有DataTable绑定数据的地方就出错,在其它页用String返回的时候行.数据库用的是Access 2003简体中文版,编程环境是Microsoft Visual Studio 2005,数据库连接用的是OLEDB
已经是第二次问这个问题了,希望能得一解,要是分不够,只要能解决问题,分可再加.Server Error in '/' Application.

看看这个吧，你在你自己的机器上无错，可能是因为只有你自己一个人访问，如果在互联网上运行，可能同时会有多个用户访问，static 容易出现错误，

怎么是显示循环这块报错呢当然报错了吧？
for 貌似根本没有执行什么语句，也没有 } 来结束 就直接 %> 了，这样是不行的
