To return a collection with repeated elements in C#, use Enumerable.Repeat method.It is part of System.Linq namespace.Let’s say you need to repeat a number twice, for that set the number and the frequency of repetition.Enumerable.Repeat(50, 2);Now assign it to a variable and display it.Example Live Demousing System; using System.Linq; class Demo { static void Main() { // repeating element 50, two times var num = Enumerable.Repeat(50, 2); // displayig repeating elements foreach (int ele in num) { Console.WriteLine(ele); } } }Output50 50
Use the Convert.ToInt32() method to convert a specified value to a 32-bit signed integer.Let us take a double variable.double doubleNum = 11.53;Now, we will convert it to Int32 using the Convert.ToInt32 method.int intNum; ntNum = Convert.ToInt32(doubleNum);Example Live Demousing System; public class Demo { public static void Main() { double doubleNum = 11.53; int intNum; intNum = Convert.ToInt32(doubleNum); Console.WriteLine("Converted {0} to {1}", doubleNum, intNum); } }OutputConverted 11.53 to 12
In a Linked List, if you want to add a node at the first position, use AddFirst method.Let’s first set a LinkedList.string [] students = {"Jenifer", "Angelina", "Vera"}; LinkedList list = new LinkedList(students);Now, to add an element as a first node, use AddFirst() method.List.AddFirst(“Natalie”);Example Live Demousing System; using System.Collections.Generic; class Demo { static void Main() { string [] students = {"Jenifer", "Angelina", "Vera"}; LinkedList list = new LinkedList(students); foreach (var stu in list) { Console.WriteLine(stu); } // add a node ...

The short type represents a 16-bit signed integer i.e. Int16.To implicitly convert a 16-bit signed integer to a Decimal, firstly set a short value.short val = -32768;To convert short to decimal, assign the value.dec = val;Let us see another example.Example Live Demousing System; public class Demo { public static void Main() { short val = -32768; decimal dec; Console.WriteLine("Implicit conversion from Int16 to Decimal"); dec = val; Console.WriteLine("Decimal : "+dec); } }OutputImplicit conversion from Int16 to Decimal Decimal : -32768
To implicitly convert char to a Decimal, firstly set a char.char c = 'p';To convert char to decimal, assign the value.decimal dec; dec = c;Let us see the above example.Example Live Demousing System; public class Demo { public static void Main() { char c = 'p'; decimal dec; Console.WriteLine("Implicit conversion from Char to Decimal"); dec = c; Console.WriteLine("Decimal : "+dec); } }OutputImplicit conversion from Char to Decimal Decimal : 112
Declare a LinkedList and add nodes to it.string [] students = {"Tim", "Jack", "Henry", "David", "Tom"}; LinkedList list = new LinkedList(students);Let us add a new node.var newNode = list.AddLast("Kevin");Now, to add a node before the given node, use the AddBefore() method.list.AddBefore(newNode, "Matt");Let us now see the complete code.Example Live Demousing System; using System.Collections.Generic; class Demo { static void Main() { string [] students = {"Tim", "Jack", "Henry", "David", "Tom"}; LinkedList list = new LinkedList(students); foreach (var stu in list) { Console.WriteLine(stu); } ...

To match an expression, use the JavaScript match() method. This method is used to retrieve the matches when matching a string against a regular expression. The following is the parameter −param − A regular expression object.If the regular expression does not include the g flag, it returns the same result as regexp.exec(string).If the regular expression includes the g flag, the method returns an Array containing all the matches.ExampleYou can try to run the following code to math an expression using JavaScript Regular Expression − JavaScript String match() Method ...

Set a LinkedList with nodes.string [] students = {"Tim", "Jack", "Henry", "David", "Tom"}; LinkedList list = new LinkedList(students);Now, use the AddLast() method to add a node at the last position.list.AddLast("Kevin");Here is the complete code with the updated LinkedList.Example Live Demousing System; using System.Collections.Generic; class Demo { static void Main() { string [] students = {"Tim", "Jack", "Henry", "David", "Tom"}; LinkedList list = new LinkedList(students); foreach (var stu in list) { Console.WriteLine(stu); } // adding a node at the end ...

The operator is used in JavaScript to check whether a property is in an object or not.ExampleYou can try to run the following code to learn how to use in operator in JavaScript −Live Demo var emp = {name:"Amit", subject:"Java"}; document.write("name" in emp); document.write(""); document.write("subject" in emp); document.write(""); document.write("MAX_VALUE" in Number); document.write(""); document.write("MIN" in Number);
Use the Linq Average() method to find the average of a sequence of numeric values.Firstly, set a sequence.List list = new List { 5, 8, 13, 35, 67 };Now, use the Queryable Average() method to get the average.Queryable.Average(list.AsQueryable());Example Live Demousing System; using System.Linq; using System.Collections.Generic; class Demo { static void Main() { List list = new List { 5, 8, 13, 35, 67 }; double avg = Queryable.Average(list.AsQueryable()); Console.WriteLine("Average = "+avg); } }OutputAverage = 25.6
