要检查 HashSet 和指定集合是否共享公共元素，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例子 −
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
