                if (lstMachineInfo != null && lstMachineInfo.Count > 0)
                {
                    BindToGridView(lstMachineInfo);
                    ShowStatusBar(lstMachineInfo.Count + " records found !!", true);
                }

Solution 1

... = lstMachineInfo.Where( x => x.date < DateTime.Now ).Last();
or
... = lstMachineInfo.Where(...).OrderDescending( x => x.date ).First();
or
etc.
