我正在部署到 IIS 6.0，这不是一项简单的任务。我终于设法连接到数据库（SQLServer 2005），但仅限于登录（ASP.NET 成员资格）。一旦我尝试单击另一个安全页面，数据库连接就会自动消失。这是次要问题。

这是我的错误信息：

特别是我正在查看这两行并想知道为什么我的本地计算机目录路径会出现在这个部署在远程服务器上的错误消息中。

有人可以告诉我这些路径从哪里显示或为什么显示？重申一下，这些路径来自我创建应用程序的开发机器。错误消息正在远程服务器上显示（通过远程桌面连接）。

谢谢

事实证明，这些路径来自我复制到远程服务器的 pdb 文件。我刚刚从我的开发机器上复制了整个应用程序以进行快速测试，并且这些文件随身携带。

我在 notepad++ 中搜索了路径字符串，虽然它实际上并没有返回字符串，但它返回了项目中的 pdb 文件路径。

我从服务器中删除了 pdb 文件，现在我的错误消息没有显示我的本地文件路径。

当 connectionString 出现拼写错误时，通常会发生此类错误。检查您的 web.config 文件中的所有内容是否正确。
