以某种方式订购的日期列表 [英] List of Dates ordered in a certain way

问题描述

我有一个日期列表(格式为yyyyMM的字符串)，如下所示:

I have a list of dates (strings in the format yyyyMM) as follows:

201608
201609
201610
201708
201709
201710

我想将它们重新排序如下:

I'd like to reorder them to be as follows:

201608
201708
201609
201709
201610
201710

我以为我可以颠倒字符串(即016102)来排序它们，但是显然，当月> = 10时，它会导致导致列表出现的问题，例如:

I thought I could reverse the strings (i.e. 016102) to order them but obviously with a month >= 10 it causes issues resulting in the list coming out like:

201610
201710
201608
201708
201609
201709

我尝试了以下操作: MyList.OrderBy(n => string.Concat(n.datestring.Reverse())).Select(n => n);

I tried the following: MyList.OrderBy(n => string.Concat(n.datestring.Reverse())).Select(n => n);

是否有一个很好的简洁方法(LINQ会很好)?感谢您的帮助.

Is there a nice succinct way of doing this (LINQ would be nice)? Thanks for any help.

推荐答案

使用LINQ，您可以按两位数字表示月份，然后按年份(和月份)排序:

Using LINQ, you order by the two digit month then the year (and month, but that shouldn't matter):

var ans = src.OrderBy(s => s.Substring(4)).ThenBy(s => s);
