LINQ方法和使用OrderBy()，Take()和ToList()的顺序 [英] LINQ method and the order to use OrderBy() , Take() , and ToList()

问题描述

我只是意识到我的LINQ方法并没有按照我的想象做任何事情.

I just realized that my LINQ methods aren't doing anything at all what I thought they were.

HighestRatedBooks = allBooks.OrderByDescending(b => b.Review.Rating).Take(5).ToList();

上面的查询未获得评分最高的5本图书，而是5本看似随机的图书.

The above query doesn't get the top 5 highest rated books, but rather 5 seemingly random books.

正确的查询是什么样的?

What would the correct query look like?

现在，这本书返回的书甚至没有具有的评级，更不用说高评级了.

Right now this is returning books that don't even have a rating, much less a high one.

推荐答案

您的查询顺序正确； Review和Rating是什么类型?

Your query is ordered correctly; what are the Review and Rating types?
