从C#中的另一个集合创建HashSet
要从另一个Collection创建HashSet，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(100);
set1.Add(200);
set1.Add(300);
Console.WriteLine("HashSet created from another collection...");
foreach(int i in set1){
Console.WriteLine(i);
}
HashSet<int> set2 = new HashSet<int>(set1);
Console.WriteLine("HashSet created from another collection...");
foreach(int i in set2){
Console.WriteLine(i);
}
}
}输出结果
这将产生以下输出-
HashSet created from another collection... 100 200 300 HashSet created from another collection... 100 200 300
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<string> set1 = new HashSet<string>();
set1.Add("Jacob");
set1.Add("Tom");
set1.Add("Harry");
set1.Add("Harry");
set1.Add("Tom");
set1.Add("Harry");
Console.WriteLine("HashSet created from another collection...");
foreach(string i in set1){
Console.WriteLine(i);
}
HashSet<string> set2 = new HashSet<string>(set1);
Console.WriteLine("HashSet created from another collection...");
foreach(string i in set2){
Console.WriteLine(i);
}
}
}输出结果
这将产生以下输出-
HashSet created from another collection... Jacob Tom Harry HashSet created from another collection... Jacob Tom Harry
