c# 对制表符分隔的文件进行排序

c# sort a tab delimited file

我看过很多关于排序制表符分隔的主题,但一直无法掌握或理解完成这段代码的任务,而且我刚刚开始使用 C#。希望有人能回答这个问题。

我想打开一个文本文件,该文件以制表符分隔并带有特定数量的字段。问题是如何使用第一列字段然后使用第二列对其进行排序。如果可能的话,我希望能够查看列表数组中的字段以进行调试。我希望这个示例以制表符分隔的形式出现。 那我当然希望能写回来

如上所述 - 你真的不能指望别人为你做这些工作......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,它可能会在您向其提供真实世界数据的那一刻崩溃,但希望能帮助您入门。

        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);
