在 windows 启动时程序启动时无法打开 sqlite 数据库文件

Question

我通过以下代码将我的程序设置为在启动时启动：

Registry.CurrentUser
    .OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true)
    .SetValue(Application.ProductName, Application.ExecutablePath);

重新启动 Windows 并登录我的帐户（具有管理员访问权限）后，程序运行成功，但是当它尝试连接到 sqlite 文件时，遇到以下异常：

当我手动运行程序时，这个问题就消失了

我尝试使用文本文件而不是数据库，但是由 Windows 运行的程序创建的文件与手动运行的程序创建的文件不同。

如何在 windows 10 上解决此问题？

Answer 1

当我在启动的情况下重新启动并运行时，当前目录是系统目录。
所以要解决这个问题，我需要使用完整路径。
