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     1
            for (int i = 0; i < renshu ;i++ )
            {
                Console.WriteLine("输入第{0}个人的成绩；",i+1);
                chengji[i] = int.Parse(Console.ReadLine());。。。。。。。赋值
            }
            Console.WriteLine("打印成绩");
            Console.ReadLine();
            Console.Clear();
            for (int i = 0; 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();

 

二维数组

 

int[,] array = new int[3, 4]{           

{1,2,3,4},            

 {3,4,5,6},             

{5,6,7,8} };            



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

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);
            }

打印图形

          
            string[,] wang = new string[,] {
            {"  ","■","■","■","■","■",""},
            {"  ","  ","  ","■","","",""},
            {"  ","  ","  ","■","","",""},
            {"  ","  ","■","■","■","",""},
            {"  ","  ","  ","■","","",""},
            {"  ","  ","  ","■","","",""},
            {"■","■","■","■","■","■","■"}
            };
            for (int i = 0; i < 7;i++ )
            {
                for (int j = 0; j < 7;j++ )
                {
                    Console.Write(wang[i,j]);
                }
                Console.WriteLine();
            }

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 = 0; i < a;i++ )
            {
                Console.Write("请输入第{0}个姓名：",(i+1));
                name[i] = Console.ReadLine();
                Console.Write("请输入第{0}个人的分数：",(i+1));
                score[i] = double.Parse(Console.ReadLine());
            }

            for (int i = 0; i < a - 1;i++ )
            {
                for (int j = i + 1; j < a;j++ )
                {
                    if (score[i] < score[j])
                    {
                        double zhong = score[i];
                        score[i] = score[j];
                        score[j] = zhong;
                        string zh = name[i];
                        name[i] = name[j];
                        name[j] = zh;
                    }
                }
            }
            Console.WriteLine("最高分的学生是：{0}，他的分数是：{1}",name[0],score[0]);

 

//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
            Console.Write("请输入班级人数：");
            int renshu = int.Parse(Console.ReadLine());
            string[] str = new string[renshu*2];
            int zhi = 0;
            for (int i = 0; i < renshu * 2; i += 2)
            {    
                zhi++;
                Console.Write("请输入第{0}个人的姓名：",zhi);
                str[i] = Console.ReadLine();
                Console.Write("请输入第{0}个人的成绩：", zhi);
                str[i+1] = Console.ReadLine();
                
            }
            for (int i = 0; i < renshu * 2-2; i += 2)
            {
                for (int j = i + 3; j < renshu * 2; j += 2)
                {
                    if (double.Parse(str[i + 1]) < double.Parse(str[j]))
                    {
                        string zhong = str[i];
                        str[i] = str[j - 1];
                        str[j - 1] = zhong;
                        zhong = str[i + 1];
                        str[i + 1] = str[j];
                        str[j] = zhong;
                    }
                }
            }
            Console.WriteLine("最高分是{0}，是{1}考得", str[1], str[0]);



                Console.ReadLine();

二维数组替换

            Console.WriteLine("输入要替换的字");
            string c = Console.ReadLine();
            Console.WriteLine("输入要替换wei的字");
            string d = Console.ReadLine();

            string[,] array = new string[4, 6] { 
               { "春","眠","不","觉","晓","，"},
               { "处","处","闻","啼","鸟","，"},
               { "夜","来","风","雨","声","，"},

            };
            for (int i = 0; i < 4; i++)
            {
                for (int j = 0; j < 6; j++)
                {
                    if (array[i, j] == c)
                    {
                        array[i, j] = d;
                    }
                }

            }
            foreach (string aa in array)
            {
