linq to sql 学习（5）关于排序的介绍

List<person> plist = new List<person>();

 

 person per = new person();

 plist.Add(new person { name = "cxx1", age = 24, sex = "男" });

 plist.Add(new person { name = "cxx2", age = 25, sex = "男" });

 plist.Add(new person { name = "cxx3", age = 26, sex = "男" });

 

 var selectperson = from person p in plist where (1==1) orderby p.age select p;

 

//②，简单方式，descending是降序

 var selectperson = from person p in plist where (1==1) orderby p.age descending select p;

 

//三，简单方式，thenby 排序，先按照年龄降序，如果相同，就按照名称降序

 selectperson.OrderByDescending(p=>p.age).ThenByDescending(p=>p.name);

 

 GridView1.DataSource = selectperson;

 GridView1.DataBind();

//①，简单方式，默认是升序
