string 結構體名

{

?// 元素一 ?// 元素二?

?

//定義一個結構體 ???????

//struct student//student就是我們自己造的新數據類型 ???????

//{ ???????

//??? public int code;//public修飾符 ???????

//??? public string name;//結構體的成員 ???????

//??? public decimal height; ???????

//}

?

?//static void Main(string[] args) ???????

//{ ???????

//??? ArrayList arr = new ArrayList(); ???????

//??? for (int i = 0; i < 3; i++) ???????

//??? { ???????

//??????? student s = new student();//定義結構體變量 ???????

//??????? Console.Write("學號："); ???????

//??????? s.code = int.Parse(Console.ReadLine()); ???????

//??????? Console.Write("姓名："); ???????

//??????? s.name = Console.ReadLine(); ???????

//??????? Console.Write("身高："); ???????

//??????? s.height = decimal.Parse(Console.ReadLine());

???????

//??????? arr.Add(s); ???????

//??? }

???????

//??? for (int i = 0; i < 2; i++) ???????

//??? { ???????

//??????? for (int j = i + 1; j < 3; j++) ???????

//??????? { ???????

//??????????? student si = (student)arr[i]; ???????

//??????????? student sj = (student)arr[j];

???????

//??????????? if (si.height < sj.height) ???????

//??????????? { ???????

//??????????????? student zhong = si; ???????

//??????????????? arr[i] = arr[j]; ???????

//??????????????? arr[j] = zhong; ???????
