Flattening of AggregateExceptions for Processing

Question

I\'m running into a few issues where I call flatten on an AggregateException, but inside there is still ANOTHER AggregateException! T

Answer 1

Yes, there's exactly what you're asking for:

AggreggateException.Flatten()

will go through and compress everything down to a single AggregateException. So you can use it to loop through the all the inner exceptions like this:

try
{
    // something dangerous
}
catch (AggregateException ae)
{ 
    foreach(var innerException in ae.Flatten().InnerExceptions)
    {
        // handle error
    }
}
