我创建了一个在Windows启动时启动的WPF应用程序。应用程序检查系统上的文件列表,如果缺少任何文件,则弹出文件路径。

我面临的问题是当我在应用程序运行时重新启动系统时,在重新启动时我的应用程序崩溃并抛出System.Threading.ThreadAbortException。下面是我在事件日志中获得的堆栈跟踪

Application: FileValidator.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

问题是什么,有人在此之前遇到过这个问题吗?

答案 0 :(得分:3)

如果没有更多的调试信息或代码可以肯定地回答,但这听起来像是CLR的一个问题。例如,如果您的应用程序在CLR运行时完全初始化之前执行,则可能会遇到类似于此处的异常。由于WPF主要是托管代码,我认为这是一种独特的可能性。

我建议您将启动条目从HKLM移至HKCU。这样,它应该在用户登录而不是在Windows启动时加载,这应该意味着CLR将在那时初始化。

如果这不起作用,MSDN建议您对ThreadAbortExceptions执行try / catch。如果WPF支持或不支持处理,我不记得我的头脑,但如果是这样,那么如果将执行移动到引导堆栈的用户登录部分并不能解决它,那么这将是你最好的选择。

Is CLR loaded and initialized everytime,when a new managed application is loaded?

您能否查看更多详情

  • 有内部异常吗?
  • 系统事件日志中是否有任何条目。
  • 请设置性能计数器并检查clr的任何故​​障(perfmon.exe)
  • 希望您了解Application类中的事件,例如DispatcherUnhandledException。请订阅这些事件。这将有助于捕获try {} catch {}
  • 中遗漏的异常
