检查 HashSet 和指定的集合是否在 C# 中共享通用元素
要检查 HashSet 和指定的集合是否共享通用元素,C# 代码如下:
示例
using System; using System.Collections.Generic; public class Demo { public static void Main(){ HashSet<int> set1 = new HashSet<int>(); set1.Add(25); set1.Add(50); set1.Add(75); set1.Add(100); set1.Add(125); set1.Add(150); Console.WriteLine("Elements in HashSet1"); foreach(int val in set1){ Console.WriteLine(val); } HashSet<int> set2 = new HashSet<int>(); set2.Add(30); set2.Add(60); set2.Add(100); set2.Add(150); set2.Add(200); set2.Add(250); Console.WriteLine("Elements in HashSet2"); foreach(int val in set2){ Console.WriteLine(val); } Console.WriteLine("Do they share common elements? "+set1.Overlaps(set2)); } }
输出
这将产生以下输出:
Elements in HashSet1 25 50 75 100 125 150 Elements in HashSet2 30 60 100 150 200 250 Do they share common elements? True
示例
现在让我们看另一个示例:
using System; using System.Collections.Generic; public class Demo { public static void Main(){ HashSet<String> set1 = new HashSet<String>(); set1.Add("Nathan"); set1.Add("Tim"); set1.Add("Tom"); set1.Add("Jack"); set1.Add("Steve"); set1.Add("David"); Console.WriteLine("Elements in HashSet1"); foreach(string val in set1){ Console.WriteLine(val); } HashSet<String> set2 = new HashSet<String>(); set2.Add("Tom"); set2.Add("Jack"); set2.Add("Kevin"); Console.WriteLine("Elements in HashSet2"); foreach(string val in set2){ Console.WriteLine(val); } Console.WriteLine("Do they share common elements? "+set1.Overlaps(set2)); } }
输出
这将产生以下输出:
Elements in HashSet1 Nathan Tim Tom Jack Steve David Elements in HashSet2 Tom Jack Kevin Do they share common elements? True
