C# में ArrayList में क्षमता को तत्वों की वास्तविक संख्या पर सेट करना

ArrayList में क्षमता को तत्वों की वास्तविक संख्या पर सेट करने के लिए, कोड निम्नानुसार है:

उदाहरण

using System; 
using System.Collections; 
public class Demo { 
    public static void Main(String[] args) { 
        ArrayList list1 = new ArrayList(); 
        list1.Add("A"); 
        list1.Add("B"); 
        list1.Add("C"); 
        list1.Add("D"); 
        list1.Add("E"); 
        list1.Add("F"); 
        list1.Add("G"); 
        list1.Add("H"); 
        list1.Add("I"); 
        Console.WriteLine("Elements in ArrayList1..."); 
        foreach (string res in list1) { 
            Console.WriteLine(res); 
        } 
        ArrayList list2 = new ArrayList(); 
        list2.Add("A"); 
        list2.Add("B"); 
        list2.Add("C"); 
        list2.Add("D"); 
        list2.Add("E"); 
        list2.Add("F"); 
        list2.Add("G"); 
        list2.Add("H"); 
        list2.Add("I"); 
        Console.WriteLine("Elements in ArrayList2..."); 
        foreach (string res in list2) { 
            Console.WriteLine(res); 
        } 
        Console.WriteLine("Count of elements in ArrayList2 = " + list2.Count); 
        list2.RemoveAt(5); 
        Console.WriteLine("Count of elements in ArrayList2 (Updated) = " + list2.Count); 
        Console.WriteLine("Enumerator iterating the ArrayList2..."); 
        IEnumerator demoEnum = list2.GetEnumerator(); 
        while (demoEnum.MoveNext()) { 
            Console.WriteLine(demoEnum.Current); 
        } 
        Console.WriteLine("Capacity of ArrayList2 = " + list2.Capacity); 
        list2.TrimToSize(); 
        Console.WriteLine("Capacity of ArrayList2 (updated) = " + list2.Capacity); 
    } 
}

आउटपुट

यह निम्नलिखित आउटपुट उत्पन्न करेगा:

Elements in ArrayList1... 
A 
B 
C 
D 
E 
F 
G 
H 
I 
Elements in ArrayList2... 
A 
B 
C 
D 
E 
F 
G 
H 
I 
Count of elements in ArrayList2 = 9 
Count of elements in ArrayList2 (Updated) = 8 
Enumerator iterating the ArrayList2... 
A 
B 
C 
D 
E 
G 
H 
I 
Capacity of ArrayList2 = 16 
Capacity of ArrayList2 (updated) = 8

उदाहरण

आइए अब एक और उदाहरण देखें:

using System; 
using System.Collections; 
public class Demo { 
    public static void Main() { 
        ArrayList list = new ArrayList(); 
        list.Add("One"); 
        list.Add("Two"); 
        list.Add("Three"); 
        list.Add("Four"); 
        list.Add("Five"); 
        list.Add("Six"); 
        list.Add("Seven"); 
        list.Add("Eight"); 
        Console.WriteLine("ArrayList elements..."); 
        foreach(string str in list) { 
            Console.WriteLine(str); 
        } 
        Console.WriteLine("ArrayList is read-only? = " + list.IsReadOnly); 
        Console.WriteLine("Does the element Six in the ArrayList? = " + list.Contains("Six")); 
        list.Insert(4, "Twelve"); 
        Console.WriteLine("ArrayList elements...UPDATED"); 
        foreach(string str in list) { 
            Console.WriteLine(str); 
        } 
        Console.WriteLine("Capacity of ArrayList = " + list.Capacity); 
        list.TrimToSize(); 
        Console.WriteLine("Capacity of ArrayList (updated) = " + list.Capacity); 
    } 
}

आउटपुट

यह निम्नलिखित आउटपुट उत्पन्न करेगा:

ArrayList elements... 
One 
Two 
Three 
Four 
Five 
Six 
Seven 
Eight 
ArrayList is read-only? = False 
Does the element Six in the ArrayList? = True 
ArrayList elements...UPDATED 
One 
Two 
Three 
Four 
Twelve 
Five 
Six 
Seven 
Eight 
Capacity of ArrayList = 16 
Capacity of ArrayList (updated) = 9
