static int SumWithFor(int n) int sum = 0; for (int i = 1; i = n; i+) sum += i; return sum; static int SumWithWhile(int n) int sum = 0, i = 1; while (i = n) sum += i; i+; return sum; static int SumWithDoWhile(int n) int sum = 0, i = 1; do sum += i; i+; while (i = n); return sum; 28、 编程输出九九乘法表。public partial class Form1 : Form public Form1() InitializeComponent(); private void button1_Click(object sender, EventArgs e) int i; int j; string a=; string, m = new string9, 9; for ( i=0;i 9;i +) for ( j = 0; j i + 1; j+) int sum = (i + 1) * (j + 1); mi, j = (i+1) + * + (j+1)+=+ sum; if (i = j) a = a + mi, j + rnrn; else a = a + mi, j + ; this.textBox1.Text = a; private void Form1_Load(object sender, EventArgs e) 29、 定义一个行数和列数相等的二维数组，并执行初始化，然后计算该数级两条对角线上的元素值之和。class Program static void Main(string args) int, nums = new int2, 2 2, 4 , 1, 3 ; string str = ; int n = 0; int m = 0; for (int i = 0; i 2; i+) str += nr; for (int j = 0; j 2; j+) str += numsi, j.ToString() + t; if (i = j) n = nums0, 0 + nums1, 1; else m = nums0, 1 + nums1, 0; str += nr; Console.WriteLine(数组:0正对角线的和为：1，负对角线的和为：2, str, n, m);30、建立一个一维数组，使用该数组列出所学习的课程名称。class Program static void Main(string args) ArrayList myAL = new ArrayList(); myAL.Add(XX); myAL.Add(YY); myAL.Add(ZZ); String strName = 课程名:; foreach (string st in myAL) strName += st + ; Console.WriteLine(strName); 31、编写程序,将一年中12个月，建立一个枚举类型数据,并对其进行调用。class Program enum month January, February, March, April, May, June, july, August, September, October, November, December ; static void Main(string args) Console.WriteLine(请输入1-12的月份：); int i = int.Parse(Console.ReadLine(); yuefen(i); public static void yuefen(int i) switch (i) case 1: Console.WriteLine(month.January); break;
