If you want to get the exception “asynchronously”, you could do:
MyAsyncMethod().
ContinueWith(t => Console.WriteLine(t.Exception),
TaskContinuationOptions.OnlyOnFaulted);
This will allow you to deal with an exception on a thread other than the “main” thread. This means you don’t have to “wait” for the call to MyAsyncMethod()
from the thread that calls MyAsyncMethod
; but, still allows you to do something with an exception–but only if an exception occurs.
Update:
technically, you could do something similar with await
:
try
{
await MyAsyncMethod().ConfigureAwait(false);
}
catch (Exception ex)
{
Trace.WriteLine(ex);
}
…which would be useful if you needed to specifically use try
/catch
(or using
) but I find the ContinueWith
to be a little more explicit because you have to know what ConfigureAwait(false)
means.
