c# - 如何修复 "' System.AggregateException' 出现在 mscorlib.dll 中”

Question

我在调试时收到未处理的异常，程序停止执行。调试器没有向我显示该行，所以我不知道要修复什么。

An unhandled exception of type 'System.AggregateException' occurred in mscorlib.dll

Additional information: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread.

Cannot obtain value of local or argument '<this>' as it is not available at this instruction pointer, possibly because it has been optimized away. System.Threading.Tasks.TaskExceptionHolder

我该如何解决这个问题？

我还找到了this question这非常相似。

Answer 1

如消息所述，您有一个任务引发了未处理的异常。

打开 Break on All Exceptions (Debug, Exceptions) 并重新运行程序。
这将向您显示最初抛出异常时的原始异常。
