【转】关于List排序的时效性

不多说了，就是说明List排序的时效性，仅仅用来备忘，改造自： http://blog.csdn.net/wanzhuan2010/article/details/6205884，感谢原作者

             listCustomer.Add(new Customer { name = "客户1", id =  });

             //Linq排序方式
             List<Customer> listCustomer3 = (from c in listCustomer
                                             orderby c.id descending //ascending
                                             select c).ToList<Customer>();
             //此处再加入新的list成员
             listCustomer1.Add(new Customer { name = "客户7", id =  });
             listCustomer2.Add(new Customer { name = "客户7", id =  });
             listCustomer3.Add(new Customer { name = "客户7", id =  });
             //
             Console.WriteLine("List.OrderBy方法升序排序");
             foreach (Customer customer in listCustomer1)
             {
                 Console.WriteLine(customer.name);
             }
             Console.WriteLine("List.OrderByDescending方法降序排序");
             foreach (Customer customer in listCustomer2)
             {
                 Console.WriteLine(customer.name);
             }
             Console.WriteLine("Linq方法降序排序");
             foreach (Customer customer in listCustomer3)
             {
                 Console.WriteLine(customer.name);
             }
             Console.ReadKey();
         }
     }
     class Customer
     {
         public int id { get; set; }
         public string name { get; set; }
     }
 }

结果展示：（新加入的成员没有参与排序）
