Question

I have execute an asynchronous method like below

System.Threading.Tasks.Task.Factory.StartNew(() => AddAttachment(information.Subject,
information.DocumentId.ToString(),
information.Sender,list.Name));

How to handle exception generated inside the method AddAttachment()?

Answer 1

You can create a continuation task to examine the one you created with StartNew:

Task outer = System.Threading.Tasks.Task.Factory.StartNew(() => AddAttachment(information.Subject, information.DocumentId.ToString(), information.Sender,list.Name))
    .ContinueWith(task => {
        if(task.IsFaulted)
        {
            AggregateException ex = task.Exception;
            //handle exception
        }
    });
