Je souhaite avoir une approche de gestion des exceptions dans ma programmation asynchrone (beginInvoke/endInvoke) dans laquelle l'un des threads (beginInvoke) échoue, alors je veux que tous les autres threads de traitement asynchrones cessent de fonctionner. S'il vous plaît suggérer une solution ?, ci-dessous je joins mon exemple de code aussi:Gestion des exceptions de multithreading asynchrone?
public List<ThreadResultDto> SendMailAsynch(List<ThreadRequestDto> requestDto)
{
List<ThreadResultDto> resultDto = new List<ThreadResultDto>();
List<IAsyncResult> asyncResults = new List<IAsyncResult>();
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;
}
FYI, l'abréviation généralement acceptée de asynchrone est Async, pas Asynch :) –
