如何分隔字符串中的段落 [英] How to separate paragraphs in a string

问题描述

我真的需要你的帮助。我试图拿一个多行字符串，并将其分成几个单独的文本。

我意识到，每当我跳过一行是那里的\\\\r的序列。之后，我以为每一行都以\\\
开头，并以\r结尾。因此，我写了以下代码。

  using System; 
使用System.Collections.Generic; 
使用System.Linq; 
使用System.Text; 
使用System.Text.RegularExpressions; 
 
命名空间ConsoleApplication15 
 {
类程序
 {
 struct ParagraphInfo 
 {
 public ParagraphInfo（string text）
 {
 int i; 
 Text = text; 
 i = text.IndexOf（'。'）; 
 FirstSentence = text.Substring（0，i）; 
} 
 
 public string Text，FirstSentence; 
} 
 
 static void Main（string [] args）
 {
 int tmp = 0; 
 int tmp1 = 0; 
 string MultiParagraphString = @AA.aa。
 
 BB.bb. 
 
 CC.cc. 
 
 DD.dd. 
 
 EE.ee.; 
 
列表< ParagraphInfo> Paragraphs = new List&ParagraphInfo>（）; 
 
 Regex NewParagraphFinder = new Regex（@[\\\
] [\r]）; 
 MatchCollection NewParagraphMatches = NewParagraphFinder.Matches（MultiParagraphString）; （int i = 0; i< NewParagraphMatches.Count; i ++）
 {
 if（i == 0）
 {
 Paragraphs.Add（new ParagraphInfo（（MultiParagraphString.Substring（0，NewParagraphMatches [0] .Index））））; 
} 
 else if（i ==（NewParagraphMatches.Count  -  1））
 {
 tmp = NewParagraphMatches [i] .Index + 3; 
 tmp1 = MultiParagraphString.Length  -  NewParagraphMatches [i] .Index  -  3; 
 Paragraphs.Add（new ParagraphInfo（MultiParagraphString.Substring（tmp，tmp1）））; 
} 
 else 
 {
 tmp = NewParagraphMatches [i] .Index + 3; 
 tmp1 = NewParagraphMatches [i + 1] .Index  -  NewParagraphMatches [i] .Index + 3; 
 Paragraphs.Add（new ParagraphInfo（MultiParagraphString.Substring（tmp，tmp1）））; 
} 
} 
 
 Console.WriteLine（MultiParagraphString）; 
 foreach（ParagraphInfo Paragraph in段落）
 {
 Console.WriteLine（Paragraph.Text）; 
 
} 
 
 
} 
} 
} 
  

当我在整个文本中一个接一个地打印了段落的每个成员时，出现了一些相当奇怪的出现。段落列表的输出是这样的：

AA.aa。

---

CC.cc。

DD。

---

DD.dd。

EE。

---

ee。

---

我不明白为什么会发生这种情况，而且我不知道为什么输出如此不同的每一次。

对不起，如果这是一团糟，但我真的需要一些帮助。
BTW如果有人有更好的主意，可以随意分享..

谢谢

解决方案

您可以尝试以下操作：

  MultiParagraphString.Split（new [] {Environment .NewLine}，
 StringSplitOptions.RemoveEmptyEntries）; 
  

这将返回一个 IEnumerable< String> 。如果要将其转换为结构，只需使用选择：

  MultiParagraphString.Split（new [] {Environment.NewLine}，
 StringSplitOptions.RemoveEmptyEntries）
 .Select（s => new ParagraphInfo（s））ToList（）; 
  

Hi guys I really need your help. I was trying to take a multi-line string which was concluded of a few paragraphs and split it into a few individual texts.

I realized that whenever I skip a line there is a sequence of \n\r in there. Afterwards I thought that each new line starts with a \n and end with a \r. Therefor, I wrote the following code.

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

namespace ConsoleApplication15
{
   class Program
   {
    struct ParagraphInfo
    {
        public ParagraphInfo(string text)
        {
            int i;
            Text = text;
            i = text.IndexOf('.');
            FirstSentence = text.Substring(0, i);
        }

        public string Text, FirstSentence;
    }

    static void Main(string[] args)
    {
        int tmp = 0;
        int tmp1 = 0;
        string MultiParagraphString = @"AA.aa.

BB.bb.

CC.cc.

DD.dd.

EE.ee.";

        List<ParagraphInfo> Paragraphs = new List<ParagraphInfo>();

        Regex NewParagraphFinder = new Regex(@"[\n][\r]");
        MatchCollection NewParagraphMatches = NewParagraphFinder.Matches(MultiParagraphString);


        for (int i = 0; i < NewParagraphMatches.Count; i++)
        {
            if (i == 0)
            {
                Paragraphs.Add(new ParagraphInfo((MultiParagraphString.Substring(0, NewParagraphMatches[0].Index))));
            }
            else if (i == (NewParagraphMatches.Count - 1))
            {
                tmp = NewParagraphMatches[i].Index + 3;
                tmp1 = MultiParagraphString.Length - NewParagraphMatches[i].Index - 3;
                Paragraphs.Add(new ParagraphInfo(MultiParagraphString.Substring(tmp, tmp1)));
            }
            else
            {
                tmp = NewParagraphMatches[i].Index + 3;
                tmp1 = NewParagraphMatches[i + 1].Index - NewParagraphMatches[i].Index+3;
                Paragraphs.Add(new ParagraphInfo(MultiParagraphString.Substring(tmp, tmp1)));
            }
        }

        Console.WriteLine(MultiParagraphString);
        foreach (ParagraphInfo Paragraph in Paragraphs)
        {
            Console.WriteLine(Paragraph.Text);

        }


    }
}
}

when I printed each member of Paragraphs one after another alongside the entire text something rather bizarre came appeared. The output of the Paragraph list was this:

AA.aa.

---

CC.cc.

DD.

---

DD.dd.

EE.

---

EE.ee.

---

I can not understand why does this keep happening, and moreover I can not figure out why is the output so different each time.

Sorry if it's a mess but I really need some help here. BTW if anyone has a better idea to do it feel free to share..

Thanks

You may try the following:

MultiParagraphString.Split(new [] {Environment.NewLine}, 
           StringSplitOptions.RemoveEmptyEntries);

That will return a IEnumerable<String>. If you want to transform them to your structures just use Select:

MultiParagraphString.Split(new [] {Environment.NewLine}, 
           StringSplitOptions.RemoveEmptyEntries)
          .Select(s => new ParagraphInfo(s)).ToList();
