ArrayList के लिए केवल-पढ़ने के लिए रैपर बनाने 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);
}
} आउटपुट
यह निम्नलिखित आउटपुट उत्पन्न करेगा -
ArrayList elements... One Two Three Four Five Six Seven Eight ArrayList is read-only? = False
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);
ArrayList list2 = ArrayList.ReadOnly(list);
Console.WriteLine("ArrayList is read-only now? = "+list2.IsReadOnly);
}
} आउटपुट
यह निम्नलिखित आउटपुट उत्पन्न करेगा -
ArrayList elements... One Two Three Four Five Six Seven Eight ArrayList is read-only? = False ArrayList is read-only now? = True
