这是 Application.Run 代码

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

    private void frmLogin2_KeyPress(object sender, KeyPressEventArgs e)
    {
        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

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

除非您对它的需要非常肯定，否则我建议将其删除 - 默认User Instance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。在这里您可以找到更多关于它是什么User Instance以及如何使用它的信息。

您的数据源是问题所在。您目前拥有：

Data Source=.\SQLEXPRESS

但是你需要的是（本地）这样的：

Data Source=(local)
