To remove the specified element from the list, the code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo {    public static void Main(String[] args) {       List list1 = new List();       list1.Add("One");       list1.Add("Two");       list1.Add("Three");       list1.Add("Four");       list1.Add("Five");       Console.WriteLine("Elements in List1...");       foreach (string res in list1) {          Console.WriteLine(res);       }       List list2 = new List();       list2.Add("India");       list2.Add("US");       ...

To check if a SortedList is read-only, the code is as follows −Example Live Demousing System; using System.Collections; public class Demo {    public static void Main(String[] args) {       SortedList list = new SortedList();       list.Add("One", "IT");       list.Add("Two ", "Operations");       list.Add("Three", "Marketing");       list.Add("Four", "Purchase");       list.Add("Five", "Sales");       list.Add("Six", "Finance");       Console.WriteLine("SortedList elements...");       foreach(DictionaryEntry d in list) {          Console.WriteLine(d.Key + " " + d.Value);       }       Console.WriteLine("List of values...SortedList"); ...

To get the keys in a SortedList object, the code is as follows −Example Live Demousing System; using System.Collections; public class Demo {    public static void Main(String[] args) {       SortedList list = new SortedList();       list.Add("One", "Finance");       list.Add("Two", "Marketing");       list.Add("Three", "Sales");       list.Add("Four", "Purchase");       list.Add("Five", "Operations");       list.Add("Six", "IT");       Console.WriteLine("SortedList elements...");       foreach(DictionaryEntry d in list) {          Console.WriteLine(d.Key + " " + d.Value);       }       Console.WriteLine("Index at key ...

To add key and value into StringDictionary, the code is as follows −Example Live Demousing System; using System.Collections; using System.Collections.Specialized; public class Demo {    public static void Main() {       StringDictionary strDict = new StringDictionary();       strDict.Add("A", "John");       strDict.Add("B", "Andy");       strDict.Add("C", "Tim");       strDict.Add("D", "Ryan");       strDict.Add("E", "Kevin");       strDict.Add("F", "Katie");       strDict.Add("G", "Brad");       Console.WriteLine("StringDictionary elements...");       foreach(DictionaryEntry de in strDict) {          Console.WriteLine(de.Key + " " + de.Value);       }   ...

To add an object to the end of the ArrayList, the code is as follows −Example Live Demousing System; using System.Collections; public class Demo {    public static void Main(String[] args){       ArrayList list = new ArrayList();       list.Add("Tim");       list.Add("Katie");       list.Add("Amy");       list.Add("Carlos");       list.Add("Chris");       list.Add("Jason");       Console.WriteLine("Elements in ArrayList...");       foreach (string res in list){          Console.WriteLine(res);       }    } }OutputThis will produce the following output −Elements in ArrayList...
