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();
}
}
