项Attachdbfilename无效

[xjl1314521wxw]

<appSettings/>
<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=192.168.1.101;AttachDbFilename=|DataDirectory|LogIn.mdf;Integrated Security=True;User Instance=True;"/>
</connectionStrings>
每次运行页面都显示Attachdbfilename无效是怎么回事？

AttachDbFilename好像只用在sqlserver Express 版,你的数据库是Express 吗

请查帮助中 “连接字符串语法 (ADO.NET)”

AttachDbFilename

你是连接SQL?

确认SQL SERVER EXPRSS已安装到本地计算机上，
并且SQL SERVER (SQLEXPRESS)服务已经成功启动。

在本地SQL服务器实例附加数据库文件 " Server=.\SQLExpress; AttachDbFilename=c:\mydbfile.mdf; Database=dbname; Database=dbname; Trusted_Connection=Yes; "
" Server=.\SQLExpress; AttachDbFilename=|DataDirectory|mydbfile.mdf; Database=dbname; Trusted_Connection=Yes; "

" Data Source=.\SQLExpress; integrated security=true; attachdbfilename=|DataDirectory|\mydb.mdf; user instance=true; "

Data Source=myServerAddress;Initial Catalog=myDataBase; User Id=myUsername;Password=myPassword;
