一、拓展代码

（1）主函数

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace wc
{
    class Program
    {
        static void Main(string[] args)
        {
            string msg = "";    //输入字符串
            WC wordcount = new WC(); //引用WC类
            Char[] c = {' '};//分隔符
            while (msg != "exit")
            {
                msg = Console.ReadLine();    //输入操作字符串
                string[] msgSplit = msg.Split(c, StringSplitOptions.RemoveEmptyEntries);//将字符串按空格分割
                wordcount.Operator(msgSplit);
            }
        }
    }
}

（2）WC类
