我希望在我的异步编程(beginInvoke/endInvoke)中有一种异常处理方法,如果任何一个线程(beginInvoke)失败,那么我希望所有其他异步处理线程停止工作。请提供一些解决方案?以下是我附加的示例代码:
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;
}
