C＃SqlConnection AttachDbFile无法识别文件路径

Question

我是C＃的新手，所以请原谅我。我试图写一个SqlConnection，但是下面的代码显示db路径开始处的红线。我已经从数据库的连接字符串复制了路径。这让我很头疼。任何帮助将不胜感激。

SqlConnection con = new SqlConnection(@"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename="D:\projects\Clinic POS\Clinic POS\Inventory.mdf";Integrated Security=True");

Answer 1

您应该删除文件名周围的引号：

SqlConnection con = new SqlConnection(@"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=D:\projects\Clinic POS\Clinic POS\Inventory.mdf;Integrated Security=True");

Answer 2

SqlConnection con = new SqlConnection("Data Source=(LocalDB)\\MSSQLLocalDB;AttachDbFilename=D:\\projects\\Clinic POS\\Clinic POS\\Inventory.mdf;Integrated Security=True");
