SQL-Server-2008R2

We have a SQL database file in folder in project and the connection string is :

SQL

public string Access_Con = @"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\DB\Financial.mdf;Integrated Security=True;User Instance=True;";

and we face following error:

Quote:
An attempt to attach an auto-named database for file failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

but when change connection string to :

C#

public string Access_Con = @"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|E:\AS-Accounting\Main-proj\accounting\Bisha_accounting\bin\Debug\DB\Financial.mdf ;Integrated Security=True;User Instance=True;";

that's run correctly.

thanks a lot.

Are you CRAZY? why did you put your database into the BIN folder??? what's wrong with you, man? The correct location is following: E:\AS-Accounting\Main-proj\accounting\Bisha_accounting\AppData\DB\Financial.mdf

if you move your DB in there your connection string would work.
The |DataDirectory| directive is mapped to the AppData application folder. Bisha, please, don't do stupid things, keep professional!
