对列表进行排序，以便最终获得特定的值 [英] Sort a List so a specific value ends up on top

问题描述

我有一个类Offer，其中包含一个已归档的类别.

I have a class Offer which contains a filed Category.

我希望特定类别的所有商品都显示在顶部，然后是其他所有商品.

I want all Offers of a specific category to appear on top, followed by all else.

我尝试过，但无济于事，您会推荐什么?

I tried this, but to no avail, what would you recommend?

Offers = Offers.OrderBy(x => x.Category == "Corporate").ToList();

推荐答案

按布尔值排序时，false(0)在true(1)之前.要首先获取与谓词匹配的元素，应使用OrderByDescending:

When you order by a boolean value false (0) comes before true (1). To get the elements that match the predicate first you should reverse the sort order by using OrderByDescending:

Offers = Offers.OrderByDescending(x => x.Category == "Corporate").ToList();
