目前集合用得最多的是Array和List,现对这2个Array和List的排序,做一些测试:
先上栗子:
Int32[] _testSort = new Int32[] { 1, 4, 2, 6, 8, 18, 3, 5, 9, 7, 11, 10 }; Array.Sort(_testSort, (a, b) => b-a); for (int i = 0; i < _testSort.Length; i += 1) { Console.WriteLine(_testSort[i]); } Console.WriteLine("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"); List<Int32> _listSort = new List<int>() { 1, 4, 2, 6, 8, 18, 3, 5, 9, 7, 11, 10 }; _listSort.Sort((a, b) => b - a); for (int i = 0; i < _listSort.Count; i += 1 ) { Console.WriteLine(_listSort[i]); } Console.ReadLine();
打印结果 :
C# Sort默认为升序 a-b , 若要将其将为降序 则是-(a-b) 也就是 b-a
