C#中两个HashSet的交集
要找到两个HashSet的交集，代码如下-
示例
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
HashSet<string> set1 = new HashSet<string>();
set1.Add("AB");
set1.Add("CD");
set1.Add("EF");
set1.Add("AB");
set1.Add("IJ");
set1.Add("KL");
set1.Add("EF");
set1.Add("OP");
Console.WriteLine("Elements in HashSet1");
foreach(string val in set1){
Console.WriteLine(val);
}
HashSet<string> set2 = new HashSet<string>();
set2.Add("EF");
set2.Add("KL");
Console.WriteLine("\nElements in HashSet2");
foreach(string val in set2){
Console.WriteLine(val);
}
Console.WriteLine("Count of elements in HashSet2 = " + set2.Count);
set2.Remove("KL");
Console.WriteLine("\nElements in HashSet2... (UPDATED)");
foreach (string res in set2){
Console.WriteLine(res);
}
Console.WriteLine("Count of elements in HashSet2 (Updated) = " + set2.Count);
Console.WriteLine("\nIs set1 a superset of set2? "+set1.IsSupersetOf(set2));
set1.IntersectWith(set2);
Console.WriteLine("\nIntersection result...");
foreach(string str in set1){
Console.WriteLine(str);
}
}
}输出结果
这将产生以下输出-
Elements in HashSet1 AB CD EF IJ KL OP Elements in HashSet2 EF KL Count of elements in HashSet2 = 2 Elements in HashSet2... (UPDATED) EF Count of elements in HashSet2 (Updated) = 1 Is set1 a superset of set2? True Intersection result... EF
示例
现在让我们来看另一个示例-
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
HashSet<int> set1 = new HashSet<int>();
set1.Add(30);
set1.Add(60);
set1.Add(70);
set1.Add(80);
set1.Add(100);
set1.Add(125);
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(70);
set2.Add(80);
set2.Add(100);
set2.Add(125);
Console.WriteLine("\nElements in HashSet2");
foreach(int val in set2){
Console.WriteLine(val);
}
set1.IntersectWith(set2);
Console.WriteLine("\nIntersection result...");
foreach(int val in set1){
Console.WriteLine(val);
}
}
}输出结果
这将产生以下输出-
Elements in HashSet1 30 60 70 80 100 125 Elements in HashSet2 30 60 70 80 100 125 Intersection result... 30 60 70 80 100 125
