Gestion des exceptions de multithreading asynchrone?

Je souhaite avoir une approche de traitement des exceptions dans ma programmation asynchrone (beginInvoke / endInvoke) dans laquelle si l’un des threads (beginInvoke) échoue, je souhaite que tous les autres threads de traitement asynchrone ne fonctionnent plus. Veuillez suggérer une solution?, Ci-dessous, je joins mon exemple de code également:

public List SendMailAsynch(List requestDto) { List resultDto = new List(); List asyncResults = new List(); foreach (ThreadRequestDto t in requestDto) { //Create a delegate. DoSomeAsynchWorkDelegate del = new DoSomeAsynchWorkDelegate(DoSomeAsynchWork); // Initiate the asynchronous call IAsyncResult a = del.BeginInvoke(t,null, del); //IAsyncResult a = del.BeginInvoke(t, null,null); asyncResults.Add(a); } foreach (IAsyncResult ar in asyncResults) { // wait for each one to complete, then call EndInvoke, passing in the IAsyncResult. // We cast ar.AsyncState to a DoSomeAsynchWorkDelegate, as we passed it in as the second parameter to BeginInvoke. ar.AsyncWaitHandle.WaitOne(); //AsyncState property of IAsyncResult is used to get the delegate that was used to call that method DoSomeAsynchWorkDelegate del = (DoSomeAsynchWorkDelegate)ar.AsyncState; // Call EndInvoke to get the result. Add the result to the list of items. resultDto.Add(del.EndInvoke(ar)); } return resultDto; } 

• Où dois-je gérer les exceptions asynchrones?
• Qu’est-ce que Microsoft.Bcl.Async?
• TaskCompletionSource lance «Une tentative de transition d’une tâche vers un état final alors qu’elle était déjà terminée»
• Async / Await VS Task.Run: Quand utiliser? Comment utiliser?
• que se passe-t-il si j’attends une tâche déjà en cours d’exécution?

 class MyClass { private ManualResetEvent workFailedEvent = new ManualResetEvent(false); public List SendMailAsynch(List requestDto) { workFailedEvent.Reset(); // --- The rest of your code as written in your post --- } private void DoAsyncWorkFirst() { try { for (int i = 0; i < 10000; i++) { if (workFailedEvent.WaitOne(0, true)) { break; } // -- Do some work here --- } } catch (MyException) { workFailedEvent.Set(); } } private void DoAsyncWorkSecond() { try { for (int j = 0; j < 20000; j++) { if (workFailedEvent.WaitOne(0, true)) { break; } // --- Do some different work here --- } } catch (MyOtherException) { workFailedEvent.Set(); } } }
