C# में HashSet में तत्वों की संख्या

C# में HashSet में तत्वों की संख्या प्राप्त करने के लिए, कोड निम्नानुसार है:

उदाहरण

using System; 
using System.Collections.Generic; 
public class Demo { 
    public static void Main() { 
        HashSet set1 = new HashSet(); 
        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); 
        } 
        Console.WriteLine("Number of elements in HashSet1 = " + set1.Count); 
        HashSet set2 = new HashSet(); 
        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("Number of elements in HashSet2 = " + set2.Count); 
        Console.WriteLine("Do they share common elements? " + set1.Overlaps(set2)); 
        Console.WriteLine("Does HashSet1 has element 60? " + set1.Contains(60)); 
        Console.WriteLine("Does HashSet2 has element 60? " + set2.Contains(60)); 
    } 
}

आउटपुट

यह निम्नलिखित आउटपुट उत्पन्न करेगा:

Elements in HashSet1 
25 
50 
75 
100 
125 
150 
Number of elements in HashSet1 = 6 
Elements in HashSet2 
30 
60 
100 
150 
200 
250 
Number of elements in HashSet2 = 6 
Do they share common elements? True 
Does HashSet1 has element 60? False 
Does HashSet2 has element 60? True

उदाहरण

आइए एक और उदाहरण देखें:

using System; 
using System.Collections.Generic; 
public class Demo { 
    public static void Main() { 
        HashSet set1 = new HashSet(); 
        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); 
        } 
        Console.WriteLine("Number of elements in HashSet1 = " + set1.Count); 
        HashSet set2 = new HashSet(); 
        set2.Add("EF"); 
        set2.Add("KL"); 
        Console.WriteLine("Number of elements in HashSet2 = " + set2.Count); 
        Console.WriteLine("Elements in HashSet2"); 
        foreach(string val in set2) { 
            Console.WriteLine(val); 
        } 
        Console.WriteLine("Is set1 a superset of set2? " + set1.IsSupersetOf(set2)); 
    } 
}

आउटपुट

यह निम्नलिखित आउटपुट उत्पन्न करेगा:

Elements in HashSet1 
AB 
CD 
EF 
IJ 
KL 
OP 
Number of elements in HashSet1 = 6 
Number of elements in HashSet2 = 2 
Elements in HashSet2 
EF 
KL 
Is set1 a superset of set2? True
