作业1:统计出txt文本里面的单词数，并找出频率出现最高的单词是哪个？
运行结果：
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) {count = key_count;tmp = new_i[i];}}Console.Write("频率出现最高的单词是：{0}\n", tmp);Console.Write("次数为：{0}\n", count);Console.ReadKey();}}}

基础代码运行成功！通过外部打开！
创建11.txt
通过外部打开：
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_A = System.IO.File.ReadAllLines(@"C:\Users\Administrator\Desktop\11.txt");string file_A = System.IO.File.ReadAllText(@"C:\Users\Administrator\Desktop\11.txt");//Console.Write(file_A);int count = 0;string tmp = "";//初始化次数var new_i = file_A.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) {count = key_count;tmp = new_i[i];}}Console.Write("频率出现最高的单词是：{0}\n", tmp);Console.Write("次数为：{0}\n", count);Console.ReadKey();}}}
