निर्दिष्ट अनुक्रमणिका पर ArrayList में एक तत्व सम्मिलित करने के लिए, कोड इस प्रकार है -
उदाहरण
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);
}
}
} आउटपुट
यह निम्नलिखित आउटपुट देगा -
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
उदाहरण
आइए एक और उदाहरण देखें -
using System;
using System.Collections;
public class Demo {
public static void Main() {
ArrayList arrList = new ArrayList();
arrList.Add(100);
arrList.Add(200);
arrList.Add(300);
arrList.Add(400);
arrList.Add(500);
Console.WriteLine("Display elements...");
IEnumerator demoEnum = arrList.GetEnumerator();
while (demoEnum.MoveNext()) {
Object ob = demoEnum.Current;
Console.WriteLine(ob);
}
arrList.Insert(4, 1000);
Console.WriteLine("Display elements...UPDATED");
demoEnum = arrList.GetEnumerator();
while (demoEnum.MoveNext()) {
Object ob = demoEnum.Current;
Console.WriteLine(ob);
}
}
} आउटपुट
यह निम्नलिखित आउटपुट देगा -
Display elements... 100 200 300 400 500 Display elements...UPDATED 100 200 300 400 1000 500
