Sql 我的 mdf 数据库文件的连接字符串

Question

我的 database.mdf 与我的 application.exe 位于同一个文件夹中。我搜索了其他问题并找到了这种方式，但是在我启动程序后出现错误

string dbPath = Application.StartupPath + "\DATABASE1.MDF";

string strConnection = @"Data Source =.\SQLEXPRESS; AttachDbFilename = [" + dbPath + "]; Integrated Security = True; Connect Timeout = 30; User Instance = True";

Answer 1

NVM 找到解决方案。问题是 []

string dbPath = Application.StartupPath + "\DATABASE1.MDF";
        string strConnection =
            @"Data Source =.\SQLEXPRESS; AttachDbFilename = " + dbPath + "; Integrated Security = True; Connect Timeout = 30; User Instance = True";
