合并多个List<T>类型并通过LINQ按指定属性排序
后台CS代码：
namespace WebFormTest.TestCollect { public partial class ListTest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { List<Person> list1 = new List<Person>(); list1.Add(new Person() { Age = 1, Name = "张三", Time = Convert.ToDateTime("2013/12/20 13:20") }); list1.Add(new Person() { Age = 5, Name = "李四", Time = Convert.ToDateTime("2013/12/20 14:20") }); list1.Add(new Person() { Age = 3, Name = "王五", Time = Convert.ToDateTime("2013/12/20 13:40") }); List<Person> list2 = new List<Person>(); list2.Add(new Person() { Age = 1, Name = "张三2", Time = Convert.ToDateTime("2013/12/20 13:20") }); list2.Add(new Person() { Age = 5, Name = "李四2", Time = Convert.ToDateTime("2013/12/20 14:20") }); list2.Add(new Person() { Age = 3, Name = "王五2", Time = Convert.ToDateTime("2013/12/20 13:40") }); list1 = list1.Concat(list2).ToList(); //合并多个list<T> list1 = list1.OrderByDescending(i => i.Time).ToList(); //降序排列 //list.OrderBy(i => i.Time);升序排列 Repeater1.DataSource = list1; Repeater1.DataBind(); } } public class Person { private int age; public int Age { get { return age; } set { age = value; } } private string name; public string Name { get { return name; } set { name = value; } } private DateTime time; public DateTime Time { get { return time; } set { time = value; } } } }
