Asp.net 2.0页面出错,数据库连接问题?
我VDW 2005编写页面,web.config中连接字符窜定义为
<add name="UserConn" connectionString="Data Source=.\SQLExpress;Integrated Security=true;AttachDBFileName=|DataDirectory|aspnetdb.mdf;User Instance=True"
providerName="System.Data.SqlClient" />
数据库是SQLexpress2005，我在办公室机子上用以上配置可以正常工作，可在家里用同样配置的机子却出现以下页面错误，请问原因：
页面出错信息：
