WP7中的UnhandledException

Question

在制作WP7应用程序时,我遇到了这个奇怪的错误,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:)

我有同样的问题.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!
