要检查SortedSet是否是指定集合的子集,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("AB"); set1.Add("BC"); set1.Add("CD"); set1.Add("EF"); 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("SortedSet1 is a subset of SortedSet2? = "+set1.IsSubsetOf(set2)); } }
输出结果
这将产生以下输出-
Elements in SortedSet1... AB BC CD EF Elements in SortedSet2... AB BC CD DE EF HI JK SortedSet1 is a subset of SortedSet2? = True
让我们看另一个例子:
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("SortedSet1 is a subset of SortedSet2? = "+set1.IsSubsetOf(set2)); } }
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 SortedSet1 is a subset of SortedSet2? = True
