Question

我需要文本帮助。我得到了一个代码，例如，查找该行是否具有偶数个单词，然后找到文本文件中的每个第二个单词。问题是我不知道如何在每个第二个单词后附加一个字符串并打印出来。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Collections;
using System.IO;

namespace sd
{
class Program
{
    const string CFd = "..\\..\\A.txt";
    const string CFr = "..\\..\\Rezults.txt";

    static void Main(string[] args)
    {


        Apdoroti(CFd, CFr);
        Console.WriteLine();

        }
    static void Apdoroti(string fd, string fr)
    {
        string[] lines = File.ReadAllLines(fd, Encoding.GetEncoding(1257));
        using (var far = File.CreateText(fr))
        {
                StringBuilder news = new StringBuilder();
                VD(CFd,news);
                far.WriteLine(news);

        }
    }


    static void VD(string fv, StringBuilder news)
    {
        using (StreamReader reader = new StreamReader(fv,
        Encoding.GetEncoding(1257)))
        {
            string[] lines = File.ReadAllLines(fv, Encoding.GetEncoding(1257));
            int nrl;
            int prad = 1;
            foreach (string line in lines)
            {
                nrl = line.Trim().Split(' ').Count();
                string[] parts = line.Split(' ');
                if (nrl % 2 == 0)
                {
                    Console.WriteLine(nrl);
                    for (int i = 0; i < nrl; i += 2)
                    {
                        int ind = line.IndexOf(parts[i]);
                        nauja.Append(parts[i]);
                        Console.WriteLine(" {0} ", news);
                    }

                }
            }
        }
    }

}

}

例如，如果我收到类似这样的文字： “丛林中的怪物很久以前，聪明的狮子生活在丛林中。他的聪明才智总是受到尊重。”

然后应打印出： “怪物修道院在丛林修道院abb曾经是abb修道院，一个聪明的abb狮子在丛林中生活着abb。他的聪明才智总是受到尊重。”

Answer 1

您可以使用正则表达式替换，例如正则表达式：

@"\w+\s\w+\s"

它可以匹配Word，Space，Word和Space。

现在将其替换为：

"$&abb "

使用方法：

using System.Text.RegularExpressions;

string text =  "Monster in the Jungle Once upon a time a wise lion lived in jungle. He was always respected for his intelligence and kindness.";
Regex regex = new Regex(@"\w+\s\w+\s");
string output = regex.Replace(text, "$&abb ");

现在您将获得所需的输出。

修改：

要使用任意数量的单词，可以使用：

@"(\w+\s){3}"

可以将量词（here 3）设置为您想要的任何内容。

Edit2 ：

如果您不想替换数字：

@"([a-zA-Z]+\s){2}"

Answer 2

您可以使用linq，首先解析空格以获取单词列表（您正在做），然后为每个奇数元素添加所需的文本，最后将数组转换回字符串。

此外，通过更改mod函数，可以很容易地将其更改为每n个单词插入一次。请记住，虽然数组索引将从0开始。

如何每n个字插入一个字符串？
