问题描述

con = new SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=global::motion.Resources.db_imageDataSet;Integrated Security=True;Connect Timeout=30;User Instance=True");

正确吗
在这里我用过sqlserver DB
它的文件是
C:\Users\r\Desktop\final output\latest Rcar - Copy\motion\Resources\db_image.mdf

因此，如何纠正它

推荐答案

如果数据库已连接，请转到Management Studio并将数据库与SQL Server实例分离.之后，您的代码应该可以在运行数据库时附加数据库.

If the database is already attached, go to Management Studio and detach the database from the SQL Server instance. After that your code should be able to attach the database when you run it.
