End Async Call

Hi,

Within a loop I have begin and invoke on a delegate.

ArrayList aresult = new ArrayList();
foreach(string companyName in companies)
{
aresult.Add(dlgt.BeginInvoke(companyName, amount, null, null));
}


The method is working correctly but I don't know how to end the invoke.

I did have this code in but it isn't always waiting for the result to complete. It doesn't seem to be waiting long enough.

foreach(IAsyncResult ar in aresult)
{
if(ar.IsCompleted == false)
ar.AsyncWaitHandle.WaitOne();
}

Do I need a callback or do I have to wait for the result to complete using a difference method.

Thanks
