To remove all elements from the Collection, the code is as follows −Example Live Demousing System; using System.Collections.ObjectModel; public class Demo {    public static void Main() {       Collection col = new Collection();       col.Add(10);       col.Add(20);       col.Add(30);       col.Add(40);       col.Add(50);       col.Add(60);       col.Add(70);       col.Add(80);       Console.WriteLine("Elements in the Collection...");       foreach(int val in col) {          Console.WriteLine(val);       }       Console.WriteLine("Does the collection has the element ...

To check whether the specified Unicode character is a punctuation mark, the code is as follow −Example Live Demousing System; public class Demo {    public static void Main() {       bool res;       char val = 'q';       Console.WriteLine("Value = "+val);       res = Char.IsPunctuation(val);       Console.WriteLine("Is the value a punctuation? = "+res);    } }OutputThis will produce the following output −Value = q Is the value a punctuation? = FalseExampleLet us see another example − Live Demousing System; public class Demo {    public static void Main() {     ...
