谢谢你的编辑。 – Cake 2011-01-22 16:40:22

错误似乎很明显 - 您对AttachDBFilename的价值无效。

|DataDirectory|应当向.mdf文件的物理路径：

c:\data dir\aspnetdb.mdf

一起：

data source=mssql2008.chaiyohosting.com;Integrated 
Security=SSPI;AttachDBFilename=c:\data dir\aspnetdb.mdf;User Instance=true

本地主机是好的，但是当我复制到真正的主机不工作。以及如何找到真正托管的物理路径。 – Cake 2011-01-22 16:51:59
