Question

我已经看过所有其他帖子，似乎帮不了我。

String constr = (@"Data Source=(localdb)\MSSQLLocalDB;
        AttachDbFilename= E:\Downloads Mainframe\Compressed\Main Menu\HRDAssets.mdf;
        initial catalog=HRDAssets; 
        Integrated Security=True;");

当我删除

AttachDbFilename= E:\Downloads Mainframe\Compressed\Main Menu\HRDAssets.mdf;

出现新问题

Answer 1

从连接字符串中删除此行

AttachDbFilename= E:\Downloads Mainframe\Compressed\Main Menu\HRDAssets.mdf;

和初始目录属性，我建议使用：

Data Source=(LocalDb)\MSSQLLocalDB;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\HRDAssets.mdf

无法将文件附加为数据库
