C#二维数组

数组格式

             一维数组：
             Console.WriteLine("输入班级人数");
             int renshu = int.Parse(Console.ReadLine());
             int[] chengji = new int[renshu];   。。。。。。。。。。 初始化
             for (int i = ; i < renshu ;i++ )
             {
                 Console.WriteLine("输入第{0}个人的成绩；",i+);
                 chengji[i] = int.Parse(Console.ReadLine());。。。。。。。赋值
             }
             Console.WriteLine("打印成绩");
             Console.ReadLine();
             Console.Clear();
             for (int i = ; i < renshu;i++ )
             {
                 Console.Write(chengji[i]+"\t");。。。。。。。。。。。。。打印方法一
             }

             //foreach(int aa in chengji  )
             //{
             //    Console.WriteLine(aa);   。。。。。。。。。打印方法2
             //}
             Console.ReadLine();

数组格式1举例

二维数组

 int[,] array = new int[, ]{           

 {,,,},            

  {,,,},             

 {,,,} };            

 3表示，有三个一维数组            

 4表示，每一个一维数组中有4个元素

二维数组

split()    以***进行分割
分割开的内容需要放置在string类型的数组中，不需要给数组定义长度

             Console.Write("请输入姓名-年龄-工作单位：");
             //"张三-33-汉企"
             string s = Console.ReadLine();
             string[] array = s.Split('-');
             foreach (string aa in array)
             {
                 Console.WriteLine(aa);
             }

一维数组例题

             输入班级人数，输入每个人的人名及分数
             排序，知道最高分是多少，是谁考得
             Console.Write("请输入班级人数：");
             int a = int.Parse(Console.ReadLine());
             string [] name = new string[a];
             double [] score =new double[a];

             for (int i = ; i < a;i++ )
             {
                 Console.Write("请输入第{0}个姓名：",(i+));
                 name[i] = Console.ReadLine();
                 Console.Write("请输入第{0}个人的分数：",(i+));
                 score[i] = double.Parse(Console.ReadLine());
             }

             for (int i = ; i < a - ;i++ )
             {
                 for (int j = i + ; j < a;j++ )
                 {
                     if (score[i] < score[j])
                     {
                         double zhong = score[i];

打印最高分方法一

//输入班级人数，输入每个人的人名及分数
            //排序，知道最高分是多少，是谁考得
            //要求使用一个一维数组
