推荐答案

1.尝试将数据库放入应用程序的App_Data文件夹中.
2.如果这不起作用，那么如果您是通过sql server management studio express创建数据库的，那么请尝试使用下面的此连接字符串.
数据源=.\ SQLEXPRESS;初始目录= CarRent;集成安全性= True
3.即使所有这些无助于尝试从sql server中删除已存在的数据库，但也请进行备份，因此，当没有附加的数据库时，它将绝对可以正常工作.

1. Try to put your data base in application''s App_Data folder.
2. If this doesn''t work than try to use this connection string below, if you created database by sql server management studio express.
Data Source=.\SQLEXPRESS;Initial Catalog=CarRent;Integrated Security=True
3. Even if all this doesn''t help than try to delete already existed database from sql server but please take a backup,So when there is no attached database,It''ll work fine absolutely.
