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...

To create a SortedSet, the code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo {    public static void Main(){       SortedSet set1 = new SortedSet();       set1.Add("AB");       set1.Add("BC");       set1.Add("CD");       set1.Add("EF");       Console.WriteLine("Elements in SortedSet1...");       foreach (string res in set1){          Console.WriteLine(res);       }       SortedSet set2 = new SortedSet();       set2.Add("BC");       set2.Add("CD");       set2.Add("DE");       set2.Add("EF");       set2.Add("AB");     ...

To check the current state of a thread, the code is as follows −Example Live Demousing System; using System.Threading; public class Demo {    public static void Main(){       Thread thread = new Thread(new ThreadStart(demo1));       ThreadPool.QueueUserWorkItem(new WaitCallback(demo2));       Console.WriteLine("Current state of Thread = "+thread.ThreadState);       Console.WriteLine("ManagedThreadId = "+thread.ManagedThreadId);    }    public static void demo1(){       Thread.Sleep(2000);    }    public static void demo2(object stateInfo){       Console.WriteLine("Thread belongs to managed thread pool? = "+Thread.CurrentThread.IsThreadPoolThread);    } }OutputThis will produce the following output −Current state of Thread = Unstarted ...

To add key/value pairs in SortedList, 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("A", "Jacob");       list.Add("B", "Sam");       list.Add("C", "Tom");       list.Add("D", "John");       list.Add("E", "Tim");       list.Add("F", "Mark");       list.Add("G", "Gary");       list.Add("H", "Nathan");       list.Add("I", "Shaun");       list.Add("J", "David");       ICollection col1 = list.Values;       Console.WriteLine("Values...");       foreach(string s ...

To get the unique identifier for the currently managed thread, the code is as follows −Example Live Demousing System; using System.Threading; public class Demo {    public static void Main(){       Thread thread = new Thread(new ThreadStart(demo1));       ThreadPool.QueueUserWorkItem(new WaitCallback(demo2));       Console.WriteLine("ManagedThreadId = "+thread.ManagedThreadId);    }    public static void demo1(){       Thread.Sleep(2000);    }    public static void demo2(object stateInfo){       Console.WriteLine("Thread belongs to managed thread pool? = "+Thread.CurrentThread.IsThreadPoolThread);    } }OutputThis will produce the following output −ManagedThreadId = 3 Thread belongs to managed thread pool? = TrueExampleLet us now ...

To get the type of the Tuple’s element, the code is as follows −Example Live Demousing System; public class Demo {    public static void Main(String[] args){       var tuple1 = Tuple.Create(150, 1500, Tuple.Create(50, 100));       var tuple2 = Tuple.Create(150, 1500, Tuple.Create(100, 200));       Console.WriteLine("Is Tuple1 equal to Tuple2? = "+tuple1.Equals(tuple2));       Console.WriteLine("HashCode of Tuple1 = "+tuple1.GetHashCode());       Console.WriteLine("Type of Tuple1 = "+tuple1.GetType());       Console.WriteLine("HashCode of Tuple2 = "+tuple2.GetHashCode());       Console.WriteLine("Type of Tuple1 = "+tuple2.GetType());    } }OutputThis will produce the following output −Is Tuple1 equal to ...
