第1关：写一个函数

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace G1{ class Program { static void Main(string[] args) { string myWords = Hello(); Console.WriteLine(myWords); } /********** Begin *********/ static string Hello()        {            return "Hello World, this is my function!";        } /********** End *********/ }}

第2关：迭代函数

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace G2{ class Program { static void Main(string[] args) { int[] a = { 3, 4, 33, 2, 121, 34, 65, 34 }; int size = a.Length - 1; int result = Max(a, size); Console.WriteLine(result); } /********** Begin *********/  static int Max(int[] array, int i)        {            int temp;            if (i == 0)            {                return array[0];            }            else            {                temp = Max(array, i - 1);                if (temp > array[i])                {                    return temp;                }                else                {                    return array[i];                }            }        } /********** End *********/ }}

第3关：变量的作用域

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace G3{ class Program { static void Main(string[] args) { outputDiscount(); } /********** Begin *********/ static int originalPrice = 100;        static float discount = 0.73F;        static void outputDiscount()        {            Console.WriteLine("After discounting, the price is " + originalPrice * discount);        } /********** End *********/ }}

第4关：引用参数和值参数

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace G4{ class Program { static void Main(string[] args) { int totalPrice = 100; ; /********** Begin *********/ int originalPrice = 100;            float discount = 0.73F; /********** End *********/ outputDiscount(originalPrice, discount, ref totalPrice); Console.WriteLine("main totalPrice is " + totalPrice); } /********** Begin *********/ static void outputDiscount(int orgPrice, float dis,ref int total)        {            total = (int)(orgPrice * dis);            Console.WriteLine("After discounting, the price is " + total);        } /********** End *********/ }}
