上代码：

using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    
    namespace ConsoleApplication1
    {
        
        class Program
        {
        
            static void Main(string[] args)
            {
        
                //文件打开
                //string file = System.IO.File.ReadAllLines(@"");
                int count = 0;
                string tmp = "";
                //初始化次数
                string words = "hihi hello,hihi,hello,hihi?";
                var new_i = words.Split(new char[] {
         ' ', ',', '.', '?' },StringSplitOptions.RemoveEmptyEntries);
                Console.Write("总的单词数量：{0}\n", new_i.Length);
                for (int i = 0; i < new_i.Length; i++)
                {
        
                    //查询每个单词出现的次数
                    var query = from key in new_i where key.ToUpperInvariant() == new_i[i].ToUpperInvariant() select key;
                    int key_count = query.Count();
                    if (key_count > count) {
