Hello prasad You can do something like this List lstDemo=new List (); DateTime now = DateTime.Now.AddSeconds(-30); if (lstDemo.Count() == 0) { lstDemo.Add(now); } if (!lstDemo.Contains(now)) { lstDemo.Add(DateTime.Now); } Please check like this

I think you have to use any keyvaluepair for the same.In key u can store the record value and in value you can store the time (Seconds rather). By using list i dont thin its possible.
