将由返回字符分隔的字符串转换为List< string>的最佳方法是什么？ [英] What is the best way to convert a string separated by return chars into a List<string>?

问题描述

将一个字符串块（一个包含返回字符的字符串，例如从一个文件或一个文本框）转换为 List< string> / code> 。

p>

  using System; 
使用System.Collections.Generic; 
使用System.Linq; 
 
命名空间TestConvert9922 
 {
 class程序
 {
 static void Main（string [] args）
 {
 string testBlock =line one+ Environment.NewLine + 
line two+ Environment.NewLine + 
line three+ Environment.NewLine + 
line four+ Environment.NewLine + 
第五行; 
 
列表< string> lines = StringHelpers.ConvertBlockToLines（testBlock）; 
 
 lines.ForEach（l => Console.WriteLine（l））; 
 Console.ReadLine（）; 
} 
} 
 
 public static class StringHelpers 
 {
 public static List< string> ConvertBlockToLines（这个字符串块）
 {
字符串fixedBlock = block.Replace（Environment.NewLine，§）; 
列表< string> lines = fixedBlock.Split（'§'）。ToList< string>（）; 
 lines.ForEach（s => s = s.Trim（））; 
回报行; 
} 
 
} 
} 
  

解决方案

 列表< string> newStr = str.Split（new [] {Environment.NewLine}，StringSplitOptions.None）.ToList（）; 
  

这会将连续换行符保留为空字符串（请参见 StringSplitOptions ）

I need to often convert a "string block" (a string containing return characters, e.g. from a file or a TextBox) into List<string>.

What is a more elegant way of doing it than the ConvertBlockToLines method below?

using System;
using System.Collections.Generic;
using System.Linq;

namespace TestConvert9922
{
    class Program
    {
        static void Main(string[] args)
        {
            string testBlock = "line one" + Environment.NewLine +
                "line two" + Environment.NewLine +
                "line three" + Environment.NewLine +
                "line four" + Environment.NewLine +
                "line five";

            List<string> lines = StringHelpers.ConvertBlockToLines(testBlock);

            lines.ForEach(l => Console.WriteLine(l));
            Console.ReadLine();
        }
    }

    public static class StringHelpers
    {
        public static List<string> ConvertBlockToLines(this string block)
        {
            string fixedBlock = block.Replace(Environment.NewLine, "§");
            List<string> lines = fixedBlock.Split('§').ToList<string>();
            lines.ForEach(s => s = s.Trim());
            return lines;
        }

    }
}

解决方案

List<string> newStr = str.Split(new[] { Environment.NewLine }, StringSplitOptions.None).ToList();

This will keep consecutive newlines as empty strings (see StringSplitOptions)
