一、代码互审：

第一次都是实现了基本功能，没有完成扩展功能，这次还有个高级功能，于是讨论了后续功能如何实现。

我们的意见基本一致，认为高级功能需要窗体来实现比较简单，于是决定用C#语言来实现。

二、部分代码

using System;
using System.Diagnostics;



namespace WordCount
{
    class program
    {
        static void Main(string[] args)
        {
            Console.Write("wc.exe -c file.c\t返回文件 file.c 的字符数\n" +
                          "wc.exe -w file.c\t返回文件 file.c 的单词总数\n" +
                          "wc.exe -l file.c\t返回文件 file.c 的总行数\n" +
                          "wc.exe -a file.c\t返回更复杂的数据(代码行/空行/注释行)\n" +
                          "wc.exe -o output.txt\t将结果输出到指定文件output.txt\n" +
                          "wc.exe -e stopList.txt\t停用词表，统计文件单词总数时，不统计该表中的单词\n" +
                          "wc.exe -s\t循环执行所有.c文件\n");
            Wordcount wc = new Wordcount();
            while (true)
            {
                Console.WriteLine("--------------------------");
                Console.WriteLine("输入命令：");


                string str = Console.ReadLine();


                Stopwatch stopwatch = new Stopwatch();
                stopwatch.Start(); // 开始监视代码运行时间

                

                wc.ExecutiveCommand(str);

                stopwatch.Stop(); // 停止监视
                TimeSpan timespan = stopwatch.Elapsed; // 获取当前实例测量得出的总时间
                string hours = timespan.TotalHours.ToString("#0.00000000 "); // 总小时
                string minutes = timespan.TotalMinutes.ToString("#0.00000000 "); // 总分钟
                string seconds = timespan.TotalSeconds.ToString("#0.00000000 "); // 总秒数
                string milliseconds = timespan.TotalMilliseconds.ToString("#0.00000000 "); // 总毫秒数
                Console.Write("运行时间  "+timespan);

            }
        }

    }
}
