Question

我已经看到很多主题在对一个制表符进行分类但是无法掌握或理解完成这段代码的任务，而我刚刚开始使用C＃。我希望有人能回答这个问题。

我想打开一个文本文件，该文件是以特定数量的字段分隔的制表符。问题是如何使用第一列字段对其进行排序，然后使用第二列。我希望能够看到列表数组中的字段，以便进行调试，如果可能的话。我希望这个示例以制表符分隔的方式出现。当然，我希望能够把它写回来。

如上所述 - 你真的不能指望别人为你做这项工作......但我很无聊。

这是一个完整的控制台应用程序形式的简单解决方案，它可能会在您提供现实世界数据的第二个版本中崩溃，但希望能让您入门。

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

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
        //Read file
        var fileContents = File.ReadAllText("file.txt");

        //split on carriage returns and line feeds, remove empty entries.
        var lines = fileContents.Split(new[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);

        //Split each line on Tab
        var splitLines = lines.Select(l => l.Split(new[] { '\t' }, StringSplitOptions.RemoveEmptyEntries));

        //splitLines is now an array of arrays.  Each splitLine entry is a line, and each entry of each splitline element is
        //a single field... so we should be able to sort how we want, e.g. by first field then by second field:
        var sortedLines = splitLines.OrderBy(sl => sl[0]).ThenBy(sl => sl[1]);

        //put back together as TSV - put tabs back.
        var linesWithTabsAgain = sortedLines.Select(sl => string.Join("\t", sl));

        //put carriage returns/linefeeds back
        var linesWithCRLF = string.Join("\r\n", linesWithTabsAgain);

        File.WriteAllText("newFile.txt",linesWithCRLF);


    }
}
}
