按第二列对锯齿状数组进行排序 [英] Sorting a jagged array by second column

问题描述

我有一个锯齿状的数组，我需要按"2"列对其进行排序:

I have a jagged array and I need to sort it by the column "2":

示例:array [x] [2]

example: array[x][2]

我大约有64个"x"，第二列("2"是)，我有4个不同的选项，但是我需要按第二个选项进行排序.

What I have is about 64 where the "x" is and in the second column (where the "2" is) I have 4 different options, but I need to sort by the second option.

推荐答案

只需使用 OrderBy :

array = array.OrderBy(inner => inner[2]).ToArray();

如果使用就地排序很重要，则可以使用 Array.Sort :

If it's important to use an in place sort then you can use Array.Sort:

Array.Sort(array, (first, second) => 
    string.Compare(first[2], second[2]));
