2. C#求最小公倍数
- class Program {
- static void Main(string[] args) {
- int n = m(20, 15); System.Console.WriteLine("最小公倍数为:" + n.ToString());
- System.Console.Read(); }
- static int f(int a, int b)//最大公约数 {
- if (a < b) { a = a + b; b = a - b; a = a - b; } return (a % b == 0) ? b : f(a % b, b);
- } static int m(int a, int b)//最小公倍数
- { return a * b / f(a, b);
- } }
3. C#汉字转拼音
- /// <summary> /// 把汉字转换成拼音(全拼)
- /// </summary> /// <param name="hzString">汉字字符串</param>
- /// <returns>转换后的拼音(全拼)字符串</returns> public static string ConvertE(string hzString)
- { // 匹配中文字符
- Regex regex = new Regex("^[u4e00-u9fa5]$"); byte[] array = new byte[2];
- string pyString = ""; int chrAsc = 0;
- int i1 = 0; int i2 = 0;
- char[] noWChar = hzString.ToCharArray(); for (int j = 0; j < noWChar.Length; j++)
