要检查两个 HashSet 对象是否相等，代码如下 −
示例
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(String[] args) {
HashSet<string> set1 = new HashSet<string>();
set1.Add("A");
set1.Add("B");
set1.Add("C");
set1.Add("D");
set1.Add("E");
set1.Add("F");
set1.Add("G");
set1.Add("H");
Console.WriteLine("Elements in HashSet1...");
foreach (string res in set1) {
Console.WriteLine(res);
}
HashSet<string> set2 = new HashSet<string>();
set2.Add("John");
set2.Add("Jacob");
set2.Add("Ryan");
set2.Add("Tom");
set2.Add("Andy");
set2.Add("Tim");
set2.Add("Steve");
set2.Add("Mark");
Console.WriteLine("Elements in HashSet2...");
foreach (string res in set2) {
Console.WriteLine(res);
}
HashSet<string> set3 = new HashSet<string>();
set3 = set2;
Console.WriteLine("Is HashSet3 equal to HashSet2? = "+set3.Equals(set2));
}
}
输出
这将产生以下输出 −
Elements in HashSet1... A B C D E F G H Elements in HashSet2... John Jacob Ryan Tom Andy Tim Steve Mark Is HashSet3 equal to HashSet2? = True
示例
让我们看另一个例子 −
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(String[] args){
HashSet<string> set1 = new HashSet<string>();
set1.Add("A");
set1.Add("B");
set1.Add("C");
set1.Add("D");
set1.Add("E");
set1.Add("F");
set1.Add("G");
set1.Add("H");
Console.WriteLine("Elements in HashSet1...");
foreach (string res in set1){
Console.WriteLine(res);
}
HashSet<string> set2 = new HashSet<string>();
set2.Add("John");
set2.Add("Jacob");
set2.Add("Ryan");
set2.Add("Tom");
set2.Add("Andy");
set2.Add("Tim");
set2.Add("Steve");
set2.Add("Mark");
Console.WriteLine("Elements in HashSet2...");
foreach (string res in set2){
Console.WriteLine(res);
}
Console.WriteLine("Is HashSet2 equal to HashSet1? = "+set2.Equals(set1));
}
}
输出
这将产生以下输出 −
Elements in HashSet1... A B C D E F G H Elements in HashSet2... John Jacob Ryan Tom Andy Tim Steve Mark Is HashSet2 equal to HashSet1? = False
