WP7中的UnhandledException

标签: c# windows-phone-7 unhandled-exception windows-phone-7.1

制作WP7应用程序时遇到这个奇怪的错误,我看不出原因。我得到的唯一输出/错误消息是“UnhandledException:参数不正确。::: ProgramName.App”

此错误随机发生,我没有从调试器获得有关如何解决它的任何信息。当我运行相同的代码两次,一次得到错误,另一次没有。所以,你们之前是否有过这个错误,也许可以告诉我它为什么会发生?这太令人沮丧了,因为它是随机发生的。任何提案都将受到高度赞赏:)

编辑:这是完整的堆栈跟踪:

我遇到了同样的问题。对我来说,修复是给每个我想要添加唯一名称的元素(例如Name = Guid.NewGuid()。ToString())。我希望这对你也有帮助!

单击Debug然后单击Exceptions,然后将Common Language Runtime Exceptions设置为“Thrown”,您应该看到堆栈跟踪。

但是,我确实认为这是一个错误,无法告诉如何在不查看代码/堆栈跟踪的情况下解决它
