如何根据数组的两个值创建数组？

Question

我有一个包含多个键的数组，

Array
(
    [0] => stdClass Object
        (
            [type] => ab_micro_list
            [title] => Testing List
            [user_id] => 70318
            [micro_list_id] => 390
        )

    [1] => stdClass Object
        (
            [type] => ab_micro_list
            [title] => Testing List
            [user_id] => 70319
            [micro_list_id] => 390
        )

)

基于这个数组我需要像这样创建数组

Array
    (
        ['Testing List'] => Array
            (
                ['users'] => Array
                         (
                               [0] => 70318
                               [1] => 70319
                         )

            )
    )

有没有办法实现这一目标。如果有人有任何建议，请分享。

Answer 1

试试这个。

int[] order = new[] {3, 1, 2}; //1 is third, 2 is first, 3 is second.

items = items.OrderBy(x => order[x.Id - 1]);
