Xamarin形式：我在代码中添加了很多TrackEvent，并且可以在非catch语句中使用TrackError

Question

我不确定我是否走在正确的轨道上。我在这个方法中放了很多跟踪事件来跟踪用户流。任何人都知道我是否投入太多。

try

同样在执行前面代码时出错的if语句中，我应该调用Crashes.TrackError来跟踪错误，或者不应该使用Crashes.TrackError，因为它不是崩溃的。

如果不应该使用Crashes.TrackError，那么记录这些错误的最佳做法是什么。我可以放在TrackEvent中但是有限制的字符可以作为属性传递。

TrackError专门用于跟踪捕获的异常。
