c# list 用法（c# list 引用）

本文实例讲述了C#中list用法。分享给大家供大家参考，具体如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 protected void Page_Load(object sender, EventArgs e) { List<string> studentNames = new List<string>(); studentNames.Add("John"); studentNames.Add("Mary"); studentNames.Add("Rose"); //显示各元素 foreach (string item in studentNames) { Response.Write(item); Response.Write(" "); } Response.Write(" "); //List转换成符号分隔字符串 string studentAllName = string.Join(",", studentNames.ToArray()); Response.Write(studentAllName); Response.Write(" "); List<decimal> studentScore = new List<decimal>(); studentScore.Add(100); studentScore.Add(98); studentScore.Add(59); //排序 studentScore.Sort(); //反转排序 studentScore.Reverse(); //显示各元素 foreach (decimal score in studentScore) { Response.Write(score); Response.Write(" "); } //总计SUM Response.Write("总分" + studentScore.Sum()); Response.Write(" "); //List中是否存在 Response.Write(studentScore.Exists(MatchPRE)); Response.Write(" "); //List转换成JSon List<Student> list = new List<Student>(); for (int i = 0; i < 5; i++) { Student a = new Student(); a.Name = "张三" + i; a.Age = i; a.Sex = "男"; list.Add(a); } string json = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(list); Response.Write(json); Response.Write(" "); } private static bool MatchPRE(decimal p)//条件匹配函数，list1中每个元素都会传入P中 //匹配后函数返回 { if (p == 100)//此句为匹配条件，如果匹配，返回，你可以随意更改成你想要的值 return true; else { return false; } } public struct Student { public string Name; public int Age; public string Sex; }
