这里是Application.Run代码

    [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new frmLogin2());
        }

    {
        if (e.KeyChar == (char)27)this.Close();
    }
}
}

这是app.config中的连接字符串

<add key="ConnStr" value="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\POS.mdf;Integrated Security=True;User Instance=True"/>

我正在使用Visual Studio 2008和SQL Server 2005 Express

Answer 1

实际上，问题出在连接字符串中，而不是Data Source=部分。这是User Instance=True

除非您对其需求绝对肯定，否则我建议将其删除 - User Instance的默认值为False。

我假设问题归结为权限/磁盘配额和其他与系统管理员相关的问题。 Here您可以找到有关User Instance是什么以及如何使用它的更多信息。

Answer 2

您的数据源是问题所在。你现在有：

Data Source=.\SQLEXPRESS

但你需要的是（本地）这样的：

Data Source=(local)

C＃Winform应用程序中的System.Data.SqlClient.Sql错误
