Use the Move method to rename a file.Let’s say the file name is −D:\tom.txtNow, to update it to the following, use the Move() method.D:\tim.txtLet us see the complete code.Exampleusing System; using System.IO; public class Demo {    public static void Main() {       File.Move(@"D:\tom.txt", @"D:\tim.txt");       Console.WriteLine("File moved successfully!");    } }

The Year Month format specifier represents a custom date and time format string.It is defined by the DateTimeFormatInfo.YearMonthPattern property.Here is the custom format string.yyyy MMMMExample Live Demousing System; using System.Globalization; class Demo {    static void Main() {       DateTime date = new DateTime(2018, 9, 7, 7, 55, 20);       Console.WriteLine(date.ToString("Y",CultureInfo.CreateSpecificCulture("en-US")));    } }OutputSeptember 2018

The following is our LinkedList.string [] employees = {"Patrick", "Robert", "John", "Jacob", "Jamie"}; LinkedList list = new LinkedList(employees);Now, let’s say you need to remove the last node i.e. “Jamie”. For that, use the RemoveLast() method.list.RemoveLast();Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       string [] employees = {"Patrick", "Robert", "John", "Jacob", "Jamie"};       LinkedList list = new LinkedList(employees);       foreach (var emp in list) {          Console.WriteLine(emp);       }       // removing last node       list.RemoveLast();       Console.WriteLine("LinkedList ...

Firstly, declare a LinkedList and add nodes.int [] num = {92, 98, 110, 130, 145, 170, 230, 240, 250, 300, 330}; LinkedList myList = new LinkedList(num);Remove the last node from the LinkedList using the RemoveLast() method.myList.RemoveLast();Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       int [] num = {92, 98, 110, 130, 145, 170, 230, 240, 250, 300, 330};       LinkedList myList = new LinkedList(num);       foreach (var n in myList) {          Console.WriteLine(n);       }       // removing last node       myList.RemoveLast();       Console.WriteLine("LinkedList after removing the last node...");       foreach (var n in myList) {          Console.WriteLine(n);       }    } }Output92 98 110 130 145 170 230 240 250 300 330 LinkedList after removing the last node... 92 98 110 130 145 170 230 240 250 300

The int type represents a 32-bit signed integer i.e. Int32.To implicitly convert an Int32 to a Decimal, firstly set a Int32 value.int val = 392;To convert Int32 to decimal, assign the value.decimal d; d = val;Let us see another example.Exampleusing System; public class Demo {    public static void Main() {       int val = 767;       decimal d;       Console.WriteLine("Implicit conversion from Int32 (integer) to Decimal");       d = val;       Console.WriteLine("Decimal : "+dec);    } }

To remove a node at the beginning of a LinkedList, use the RemoveFirst() method.string [] employees = {"Peter", "Robert", "John", "Jacob"}; LinkedList list = new LinkedList(employees);Now, to remove the first element, use the RemoveFirst() method.list.RemoveFirst();Let us see the complete example.Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       string [] employees = {"Peter", "Robert", "John", "Jacob"};       LinkedList list = new LinkedList(employees);       foreach (var emp in list) {          Console.WriteLine(emp);       }       // removing first node       list.RemoveFirst(); ...

The following is our string array −string[] arr = { "Java", "HTML", "CSS", "JavaScript"};Use the Aggregate method and set a Lambda Expression to find the string with more number of characters.Here, the resultant string should have more number of characters than the initial seed value i.e. “jQuery” here.Example Live Demousing System; using System.Linq; class Demo {    static void Main() {       string[] arr = { "Java", "HTML", "CSS", "JavaScript"};       string res = arr.AsQueryable().Aggregate("jQuery", (longest, next) => next.Length >       longest.Length ? next : longest, str => str.ToLower());       Console.WriteLine("String with more ...

Let’s say the following is our LinkedList with integer nodes.int [] num = {29, 40, 67, 89, 198, 234}; LinkedList myList = new LinkedList(num);Now, if you want to remove the first element from the list, then use the RemoveFirst() method.myList.RemoveFirst();Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       int [] num = {29, 40, 67, 89, 198, 234};       LinkedList myList = new LinkedList(num);       foreach (var n in myList) {          Console.WriteLine(n);       }       // removing first node       myList.RemoveFirst();       Console.WriteLine("LinkedList after removing the first node...");       foreach (var n in myList) {          Console.WriteLine(n);       }    } }Output29 40 67 89 198 234 LinkedList after removing the first node... 40 67 89 198 234

To represent Int32 as a Hexadecimal string in C#, use the ToString() method and set the base as the ToString() method’s second parameter i.e. 16 for Hexadecimal.Int32 represents a 32-bit signed integer.Firstly, set an Int32 variable.int val = 9898;Now, convert it to a hexadecimal string by including 16 as the second parameter.Convert.ToString(val, 16)Example Live Demousing System; class Demo {    static void Main() {       int val = 9898;       Console.WriteLine("Integer: "+val);       Console.Write("Hex String: "+Convert.ToString(val, 16));    } }OutputInteger: 9898 Hex String: 26aa

The following is our LinkedList list with nodes.string [] students = {"Katie", "Jennifer", "Amy", "Vera"}; LinkedList list = new LinkedList(students);Now let us remove a node with the string element “Vera”.For that, use Remove() method.list.Remove("Vera");Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       string [] students = {"Katie", "Jennifer", "Amy", "Vera"};       LinkedList list = new LinkedList(students);       foreach (var stu in list) {          Console.WriteLine(stu);       }       // removing a node       list.Remove("Vera");       Console.WriteLine("LinkedList after removing ...
