我有一个使用.net 4.0框架的IIS7应用程序。应用程序池对应用程序的文件夹具有权限(读/写/执行),并具有(选择/读取/连接)数据库的权限。 IIS7接受aspx文件,一切似乎都很好,但是当我从服务器外部调用ti时,我收到404错误。
当我进入服务器并拨打http://localhost链接时,我收到此错误
Server Error in '/Phonebook/PhoneBook' Application.

如果我调用default-defaut.html文件,它可以正常工作,但如果我调用default-defaut.aspx则不行。但是在daufault页面设置中,aspx和html都在那里。
此外,它似乎与sql server有关,但我不明白在哪里调试
我不知道这是做什么的。有人可以帮忙吗?

方法DBUtils.Execute似乎有错误。你对page_load或page_load之前的任何事件有什么看法?

错误告诉您问题的确切位置:
DBUtils类的第3行有一个错误:
PhoneBookApplication.DBUtils.Execute(SqlCommand command) +399
IIS不是问题。如果您收到404错误是因为您没有找到正确的URL。
