一、拓展程式碼

（1）主函式

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

 
namespace wc
{
    class Program
    {
        static void Main(string[] args)
        {
            string msg = "";    //輸入字串
            WC wordcount = new WC(); //引用WC類
            Char[] c = {' '};//分隔符
            while (msg != "exit")
            {
                msg = Console.ReadLine();    //輸入操作字串
 

                string[] msgSplit = msg.Split(c, StringSplitOptions.RemoveEmptyEntries);//將字串按空格分割
                wordcount.Operator(msgSplit);
            }
        }
    }
}

（2）WC類

二、拓展功能展示

三、靜態程式碼檢查

四、單元測試

五、個人總結

通過這次作業，學會了使用VS自帶的單元測試工具。同時，結隊程式設計互相討論，互相提供靈感，對程式設計的幫助很大。但是實在沒有找到靜態程式碼測試工具，只能看VS自帶的錯誤提示，沒有學習到靜態程式碼工具的使用，有一些遺憾。
