推荐答案

List<decimal> scores = GetScores();
List<Fruit> fruit = GetFruit();

List<Tuple<decimal, Fruit>> sortedPairs = scores
  .Zip(fruit, (s, f) => Tuple.Create(s, f))
  .OrderBy(x => x.Item1)
  .ToList();

scores = sortedPairs.Select(x => x.Item1).ToList();
fruit = sortedPairs.Select(x => x.Item2).ToList();

现在您所要做的就是实现Zip，OrderBy，Select，ToList和Tuple.

Now all you have to do is implement Zip, OrderBy, Select, ToList and Tuple.
