Hi, You can give try to this. static void ParallelForEach (IEnumerable source, Action action) { using (var countEvent = new CountdownEvent(source.Count())) { foreach (var item in source) { ThreadPool.QueueUserWorkItem(i => { action((T)i); countEvent.Signal(); }, item); } countEvent.Wait(); } }

implement this class for parallel foreach public class Parallel { public static void ForEach (IEnumerable items, Action action) { if (items == null) throw new ArgumentNullException("enumerable"); if (action == null) throw new ArgumentNullException("action"); var resetEvents = new List (); foreach (var item in items) { var evt = new ManualResetEvent(false); ThreadPool.QueueUserWorkItem((i) => { action((T)i); evt.Set(); }, item); resetEvents.Add(evt); } foreach (var re in resetEvents) re.WaitOne(); } }
