將字典轉換為元組列表

Question

如何以最短的方式將字典轉換為元組列表（C#）？

Dictionary<long,int> myDico = new Dictionary<long,int>();
IList<Tuple<long, int>> applyOnTree = myDico.Something();

Answer 1

像這樣的東西？

var list = myDico.Select(x => new Tuple<long, int>(x.Key, x.Value)).ToList();

Answer 2

你可以試試這個

var applyOnTree = myDico.Select(x => Tuple.Create(x.Key, x.Value)).ToList();

Answer 3

System.ValueTuple (struct, mutable field) 是大多數時候的方法。 System.Tuple (class, readonly) 不太有趣。

List<(long,int)> tuples = new Dictionary<long, int>().Select(x => (x.Key, x.Value)).ToList();
