按照在另一个列表C#中找到的值对列表进行排序

Question

假设我有以下两个列表..

var unscoredList = new List<string> { "John", "Robert", "Rebecca" };

var scoredList = new List<WordScore>
{
    new WordScore("John", 10),
    new WordScore("Robert", 40),
    new WordScore("Rebecca", 30)
};

有没有办法我可以unscoredList通过scoredList首先出现得分最高的单词的值对值进行排序unscoredList？

如果需要,下面是WordScore类.

public class WordScore {
    public string Word;
    public int Score;

    public WordScore(string word, int score) {
        Word = word;
        Score = score;
    }
}

Answer 1

如果您不需要就地排序,则可以执行以下操作:

var scoreLookup = scoredList.ToDictionary(l => l.Word, l => l.Score);

var result = unscoredList.OrderByDescending(l => scoreLookup[l]);

或者,您可以使用:

unscoredList.Sort((l,r) => scoreLookup[r].CompareTo(scoreLookup[l]));

当然,应该进行一些完整性检查(scoredList中的重复值,unscoredList中不在scoredList中的值等).
