C# 我能从这样的碰撞信息中得到有用的信息吗？

我使用的是Xamarin.iOS，它是Objective-C的C#包装器

我有一个任务中发生的崩溃，但该信息没有用处，如下所示：

*** Terminating app due to uncaught exception 'System.AggregateException', reason: 'System.AggregateException: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property.

这些数字意味着什么？我能从这些数字中检索出调用了哪个文件甚至哪个方法吗？

上面的崩溃信息显示了崩溃期间活动帧的列表

1   CoreFoundation                       0x000000018da17cec 0x18d93b000 + 904428

上述样本框架的详细信息

1 : Frame Number

CoreFoundation : Framework Name

0x000000018da17cec : Address of the called Function

0x18d93b000 : File Name

+8740 : Line of the Code

要从地址中获取函数名和文件名，我们需要将崩溃报告符号化

您在这个问题中发布的崩溃日志的一部分显示了所有默认的iOS框架，因此即使在符号化之后，您也可能无法获得那么多有用的信息。您需要查找带有应用程序名称的活动框架，这可能会为您提供有用的信息

有许多第三方库可供我们用于事故报告，如Fabric、曲棍球应用程序、Flurry

似乎支持Xamarin，希望能有所帮助。

您可以使用Xcode或atos terminal命令将这些数字符号化-我所要做的就是将报告符号化。我现在使用hockeyApp，每次上传构建时我都会上传我的dsyms给他们，这样每次崩溃都可以立即被符号化
