Question

我在WPF中创建了一个应用程序，它只是轮询应用程序。现在我想在Windows Startup上启动该应用程序（用户登录后）。我还使用Wix Toolset创建了一个安装程序包，它将注册表项添加到 Software \ Microsoft \ Windows \ CurrentVersion \ Run 。程序实际上尝试运行但没有错误。我从Windows 事件查看器中得到错误，我无法理解这个错误的产生位置。

堆栈追踪：

Application: icBlync.exe
Framework Version: v4.0.30319

请帮助。

当App从Startup启动时，工作目录不是已安装的目录。因此，当应用程序尝试加载图标时，它会提供 System.IO.DirectoryNotFoundException 。

我刚刚使用以下命令将工作目录更改为Installed目录：

Environment.CurrentDirectory = System.IO.Path.GetDirectoryName(System.Windows.Forms.Application.ExecutablePath);

Wpf应用程序不是在启动时启动而是手动运行？
