c# - 无法打开，因为它是 706 版本。此服务器支持 662 及更早版本。不支持降级路径

Question

当我尝试运行我的网站(使用 aspx)时，出现了这个问题:

An exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll but was not handled in user code

Additional information: The database 'C:\USERS\XXXX\DESKTOP\BERMAN\APP_DATA\DATABASE.MDF' cannot be opened because it is version 706. This server supports version 662 and earlier. A downgrade path is not supported.

Could not open new database 'C:\USERS\XXXX\DESKTOP\BERMAN\APP_DATA\DATABASE.MDF'. CREATE DATABASE is aborted.

An attempt to attach an auto-named database for file C:\Users\XXXX\Desktop\Berman\app_data\DataBase.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

怎么办？

Answer 1

看起来 Database.mdf 文件是使用比服务器上安装的版本 (2008) 更高版本的 SQL Server Express (2012) 创建的。使用最新版本的 SQL Server Express 升级服务器。
