System.InvalidOperationException: Collection was modified

Question

I am getting a following exception while enumerating through a queue:

System.InvalidOperationException: Collection was modified; enumeration opera

Answer 1

How about some LINQy goodness?

private bool extractWriteActions(out List channelWrites)
{

   channelWrites= tpotActionQueue.Where(x => x is WriteChannel).ToList()

   foreach(WriteChannel channel in channelWrites) {
      channel.Status = RecordStatus.Batched;
   }

  return ( channelWrites.Count > 0);
}
