                     }}
        };
}

public static class LinqUpdates
{

public static void Update<T>(this IEnumerable<T> source, Action<T> action)
{
foreach (var item in source)
action(item);
}

}


i WANT TO UPDATE THE ABOVE LIST USING THE BELOW METHOS HOW?

i AM TRYING THIS WAY NOT POSSIBLE

Method is

public void Update(Employee obj)
        {
            var list = loadList;
            loadList.Where(p => p.EmpNo == obj.EmpNo).Update();
        }


I want to update whole List Ex: empList

in that list 3 classes are their

Update data the total list element by element ?

not possible to update single statement update whole list

like EX: empList.Update(obj)
