List等数据集多栏位排序

List<Customer> list = new List<Customer>();
list.Add(new Customer { id = 1, name = "刘德华", age = 56, period=40 });
list.Add(new Customer { id = 2, name = "张学友", age = 52, period = 35 });
list.Add(new Customer { id = 3, name = "黎明", age = 58, period = 33 });
list.Add(new Customer { id = 4, name = "郭富城", age = 60, period = 36 });
list.Add(new Customer { id = 5, name = "古天乐", age = 60, period = 30 });
var sortlist = list.OrderBy(o=>o.age).ThenBy(t=>t.period).ToList();
