For both the Parallel.For and Parallel.ForEach methods as well as for PLINQ, exceptions are collected into an AggregateException object and rethrown in the context of the calling thread. All exceptions are propagated back to you. To learn more about exception handling for parallel loops, see ...
public static partial class Program { public static void Main() { HandleThree(); } public static void HandleThree() { var task = Task.Run( () => throw new CustomException("This exception is expected!")); try { task.Wait(); } catch (AggregateException ae) { foreach (v...
Parallel.Foreach），原来.NET已经实现这项功能而且语法简化的异常简单。
Exception handling in Task parallel library: while(!task1.IsCompleted){}// Or Task.Wait(); and catch the exception in UI thread; if(task.status==TaskStatus.falted){ foreach(var e in task1.Exception.InnerException){ //Log the exception ...

TPL默认是Parallel.ForEach使用场景是对CPU敏感的,TPL会持续创建线程,直到你的CPU利用率达100%;问题是你的使用场景如果不是CPU敏感的,例如是I/O敏感的,TPL想尽可能的利用你的CPU,所以检测你的CPU利用率,如果还不是100%就会一直创建线程...直到内存耗尽。所以,使用要注意使用场景十分CPU敏感的,另外可以加一个参数...

9. The loop continues until the maximum number of concurrent tasks is reached. If the limit is reached, the script waits for 1 second before checking again. 10. Error handling is implemented to log any errors that occur during the execution of the script. ...
