C#6.0新添加了 lambda的强力支持,用lambda的确可以节省好多代码,让代码看起来更简洁,更直观; 这里做一个笔记,C#的匿名委托 Demo 1 class Program 2 { 3 static void Main(string[] args) 4 { 5 6 List<tb_User> list = new List<tb_User>{ 7 new tb_User{ Id = 1001, Name = "susan", Age = 10 }, 8 new tb_User{ Id = 1002, Name = "susan", Age = 10 }, 9 new tb_User{ Id = 1003, Name = "susan", Age = 10 }, 10 new tb_User{ Id = 1004, Name = "susan4", Age = 10 }, 11 new tb_User{ Id = 1005, Name = "susan5", Age = 10 }, 12 new tb_User{ Id = 1006, Name = "susan6", Age = 17 }, 13 new tb_User{ Id = 1007, Name = "susan7", Age = 18 }, 14 new tb_User{ Id = 1008, Name = "susan8", Age = 19 }, 15 new tb_User{ Id = 1009, Name = "susan9", Age = 20 }, 16 new tb_User{ Id = 1010, Name = "susan10", Age = 21 } 17 }; 18 19 var list1 = list.Find( 20 tb_User => { return tb_User.Age == 18; } 21 ); 22 23 var list2 = list.Find( 24 delegate (tb_User user){ 25 return user.Age == 18; 26 } 27 ); 28 Console.WriteLine(list2.Age); 29 30 31 32 Console.ReadKey(); 33 } 34 } 35 public class tb_User 36 { 37 public int Id { get; set; } 38 public string Name { get; set; } 39 public int Age { get; set; } 40 41 } 这里list1和list2实现的是同一个功能,但是用list1的方法显然要简洁很多! 仅仅作为笔记,参考! 本文为七小站主原创作品,转载请注明出处:http://www.cnblogs.com/qixiaoyizhan/ 且在文章页面明显位置给出原文链接,否则保留追究法律责任的权利。 |
