要检查SortedSet是否是指定集合的超集,代码如下-
using System; using System.Collections.Generic; public class Demo { public static void Main(){ SortedSet<string> set1 = new SortedSet<string>(); set1.Add("CD"); set1.Add("CD"); set1.Add("CD"); set1.Add("CD"); Console.WriteLine("Elements in SortedSet1..."); foreach (string res in set1){ Console.WriteLine(res); } SortedSet<string> set2 = new SortedSet<string>(); set2.Add("BC"); set2.Add("CD"); set2.Add("DE"); set2.Add("EF"); set2.Add("AB"); set2.Add("HI"); set2.Add("JK"); Console.WriteLine("Elements in SortedSet2..."); foreach (string res in set2){ Console.WriteLine(res); } Console.WriteLine("SortedSet2 is a superset of SortedSet1? = "+set2.IsSupersetOf(set1)); } }
输出结果
这将产生以下输出-
Elements in SortedSet1... CD Elements in SortedSet2... AB BC CD DE EF HI JK SortedSet2 is a superset of SortedSet1? = True
让我们看另一个例子:
using System; using System.Collections.Generic; public class Demo { public static void Main(){ SortedSet<int> set1 = new SortedSet<int>(); set1.Add(10); set1.Add(20); set1.Add(30); set1.Add(40); set1.Add(50); set1.Add(60); Console.WriteLine("Elements in SortedSet1..."); foreach (int res in set1){ Console.WriteLine(res); } SortedSet<int> set2 = new SortedSet<int>(); set2.Add(10); set2.Add(20); set2.Add(30); set2.Add(40); set2.Add(50); set2.Add(60); set2.Add(70); set2.Add(80); set2.Add(90); set2.Add(100); Console.WriteLine("Elements in SortedSet2..."); foreach (int res in set2){ Console.WriteLine(res); } Console.WriteLine("SortedSet2 is a superset of SortedSet1? = "+set2.IsSupersetOf(set1)); } }
输出结果
这将产生以下输出-
Elements in SortedSet1... 10 20 30 40 50 60 Elements in SortedSet2... 10 20 30 40 50 60 70 80 90 100 SortedSet2 is a superset of SortedSet1? = True
