代码

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace ConsoleApplication1{    class Program    {        static void Main(string[] args)        {            Console.WriteLine("请输入一串数字:");            string s = Console.ReadLine();            char[] chnum = s.ToCharArray();            int count = 0, Count = 0, other = 0, figure = 0;            for (int i = 0; i < s.Length; i++)            {                if ((char)s[i] > 'a' && (char)s[i] < 'z')                {                    count++;                }                if ((char)s[i] > 'A' && (char)s[i] < 'Z')                {                    Count++;                }                if ((int)s[i] > '0' && (int)s[i] < '9')                {                    figure++;                }                else                {                    other++;                }            }            Console.Write("大写字母的个数为:");            Console.WriteLine(Count);            Console.Write("小写字母的个数为:");            Console.WriteLine(count);            Console.Write("数字的个数为:");            Console.WriteLine(figure);            Console.Write("其他字符的个数为:");            Console.WriteLine(other);            Console.ReadKey();        }    }}
