函数

void是没有返回值,括号内是参数

private只能在当前类里面用,public公用的,可以在整个命名空间使用

函数 函数创建与使用 示例一 身份证截取  static public string jiequ(string a)         {

            string p = a.Substring(6, 8);             Console.WriteLine(p);             string n = a.Substring(6, 4);             string y = a.Substring(10, 2);             string d = a.Substring(12, 2);             return "您的生日是:" + n + "年" + y + "月" + d + "日";

        }         static void Main(string[] args)         {             Console.WriteLine("输入身份证号:");             Console.WriteLine(jiequ(Console.ReadLine()));                     }

一群羊赶到村庄去卖,美国一个村庄对视之前总数的1/2+1只,过了7个村庄之后还剩两只,问最初赶了几只羊?? 递归法        public int dgqiuyang(int cun)         {             int sum = 0;             if (cun==7)             {                 return 2;             }             sum=2*(dgqiuyang(cun+1)+1);             return sum;         }         static void Main(string[] args)         {             hanshu hb = new hanshu();             double x = hb.dgqiuyang(1);             Console.Write("求羊"+x);                 Console.ReadLine ();         }

打印图形 菱形  static public void lingxing(int x)         {

            string t = "※";             for (int i = 0; i < x - 1; i++)//菱形上部             {

                for (int k = x; k > i + 1; k--)                 {

                    Console.Write("  ");

                }                 for (int k = 2 * x; k > 2 * (x - i) - 1; k--)                 {

                    Console.Write(t);                 }

                Console.WriteLine();             }

            for (int i = 0; i < x; i++)//菱形下部             {                 for (int k = 0; k < i; k++)                 {

                    Console.Write("  ");

                }                 for (int k = 0; k < 2 * (x - i) - 1; k++)                 {

                    Console.Write(t);                 }                 Console.WriteLine();             }

        }

方形         static public void fangxing(int x,int y)         {             string t = "※";             for (int i = 0; i < y; i++)             {

                for (int k = 0; k <x; k++)                 {                     Console.Write(t);                 }                 Console.WriteLine();             }                       }  平行四边形                static public void pingxing(int x,int y)         {             string t = "※";             for (int i = 0; i < y ; i++)             {

                for (int k = x-i; k<=x; k++)                 {

                    Console.Write("  ");

                }                 for (int k =0; k <x; k++)                 {

                    Console.Write(t);                 }

                Console.WriteLine();             }         } static void Main(string[] args)  {      while (true)      {           try      {

               Console.WriteLine("请选择:");                Console.WriteLine("1:菱形 \t2:方形 \t3:平行四边形\t4:尖三角\t5:杨辉三角\t6:瘦菱形");                int n = Convert.ToInt32(Console.ReadLine());                switch (n)                {                    case 1:                        Console.Write("需要打印行数:");                        int m = Convert.ToInt32(Console.ReadLine());                        lingxing(m);                        break;                    case 2:                        Console.Write("需要打印长度:");                        int m1 = Convert.ToInt32(Console.ReadLine());                        Console.Write("需要打印宽度:");                        int m2 = Convert.ToInt32(Console.ReadLine());                        fangxing(m1,m2);                        break;                    case 3:                         Console.Write("需要打印长度:");                        int m3 = Convert.ToInt32(Console.ReadLine());                        Console.Write("需要打印行数:");                        int m4 = Convert.ToInt32(Console.ReadLine());                        pingxing(m3,m4);                        break;                     default:                        break;                }
