TaskScheduler.UnobservedTaskException事件在.NET中用于在任务(Task)中发生的异常没有被捕获和处理的情况下触发。这个事件是TaskScheduler类的一部分,用于全局地捕获和处理那些未被任何任务等待(即“未观察到的”)任务中的异常。由于异步编程模型允许任务独立于启动它们的线程继续执行,如果这些任务中的异常没有被捕获,它们...
Task 中的异常# 在C# 中,写这样一段代码: Task.Run(() => { throw new InvalidOperationException("throw in task"); }); 这里异常在 Task 里面没有被捕获,外面也没有 await Task 的执行结果,那么,这个异常就成了游离的状态。 如果订阅了 TaskScheduler.UnobservedTaskException 事件,TaskScheduler.Unobserved...

C#的async/await功能基于TPL的Task对象,每个await操作符都是“等待”一个Task完成。在之前(或者说如今)的TPL中,Task对象的析构函数会查看它的Exception对象有没有被“访问”过,如果没有,且Task对象出现了异常,则会抛出这个异常,最终导致的结果往往便是进程退出。因此,我们必须小心翼翼地处理每一个Task对象的错误,...
