0	using(Customer cs=new Customer()) { } is the short and performance wise better approach . The reason being we are creating an object of Customer in one shot and using GC feature to dispose it using using. ---Kishor kishor kumar Harsh_rc, if this helps please login to Mark As Answer. \| Alert Moderator

0	In all of your scenarios objects are created anayway , but the purpose of USING is to allow GC to take care of its dispose.and developer has not to worry about anything. kishor kumar Harsh_rc, if this helps please login to Mark As Answer. \| Alert Moderator
