要检查SortedSet对象是否是指定集合的正确子集,代码如下-
using System; using System.Collections.Generic; public class Demo { public static void Main(){ SortedSet set1 = new SortedSet(); set1.Add(20); set1.Add(40); set1.Add(60); set1.Add(80); set1.Add(100); set1.Add(120); set1.Add(140); Console.WriteLine("Elements in SortedSet1..."); foreach (int res in set1){ Console.WriteLine(res); } SortedSet set2 = new SortedSet(); set2.Add(20); set2.Add(40); set2.Add(60); Console.WriteLine("Elements in SortedSet2..."); foreach (int res in set2){ Console.WriteLine(res); } Console.WriteLine("SortedSet2 is a proper subset of SortedSet1? = "+set2.IsProperSubsetOf(set1)); } }
输出结果
这将产生以下输出-
Elements in SortedSet1... 20 40 60 80 100 120 140 Elements in SortedSet2... 20 40 60 SortedSet2 is a proper subset 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 set1 = new SortedSet(); set1.Add(20); set1.Add(40); set1.Add(60); Console.WriteLine("Elements in SortedSet1..."); foreach (int res in set1){ Console.WriteLine(res); } SortedSet set2 = new SortedSet(); set2.Add(20); set2.Add(40); set2.Add(60); Console.WriteLine("Elements in SortedSet2..."); foreach (int res in set2){ Console.WriteLine(res); } Console.WriteLine("SortedSet2 is a proper subset of SortedSet1? = "+set2.IsProperSubsetOf(set1)); } }
输出结果
这将产生以下输出-
Elements in SortedSet1... 20 40 60 Elements in SortedSet2... 20 40 60 SortedSet2 is a proper subset of SortedSet1? = False
