1) If the processing method (in bot class) has signature void xxxx() (or it can be changed to this form) you can use System.Threading namespace: ThreadStart threadDelegate = new ThreadStart(bot.xxxx); Thread newThread = new Thread(threadDelegate); newThread.Start(); call code above in a loop for every bot in list 2)if you need pass parameters to process method You can call processing methods of each bot asynchronously using method ISynchronizeInvoke.BeginInvoke more information can be found on msdn http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpovrasynchronousprogrammingoverview.asp I hope you'll find this informations helpful
