The "C" (or currency) format specifier is used to convert a number to a string representing a currency amount.Let us see an example.double value = 139.87;Now to display the above number until three decimal places, use (“C3”) currency format specifier.value.ToString("C3", CultureInfo.CurrentCulture)Let us see another example.Example Live Demousing System; using System.Globalization; class Demo {    static void Main() {       double value = 234.66;       // displays $       Console.WriteLine(value.ToString("C", CultureInfo.CurrentCulture));       Console.WriteLine(value.ToString("C3", CultureInfo.CurrentCulture));    } }Output$234.66 $234.660

Here is our LinkedList.int [] num = {1, 3, 7, 15}; LinkedList list = new LinkedList(num);To check whether the list contains an element or not, use the Contains() method. The following example checks for node 3 in the list.list.Contains(3)Above, returns True since the element is found as shown below −Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       int [] num = {1, 3, 7, 15};       LinkedList list = new LinkedList(num);       foreach (var n in list) {          Console.WriteLine(n);       }   ...

The following is the array and its elements −int[] arr = { 10, 20, 15 };Set negative value to positive elements.if (arr[i] > 0) arr[i] = -arr[i];Loop the above until the length of the array.for (int i = 0; i < arr.Length; i++) {    Console.WriteLine(arr[i]);    if (arr[i] > 0)    arr[i] = -arr[i]; }Let us see the complete example.Example Live Demousing System; public class Demo {    public static void Main(string[] args) {       int[] arr = { 10, 20, 15 };       Console.WriteLine("Displaying elements...");       for (int i = 0; i < ...

The "D" format specifier represents a custom date and time format string.The format string is defined by culture's DateTimeFormatInfo.LongDatePattern property.The custom format string is −dddd, dd MMMM yyyyExample Live Demousing System; using System.Globalization; class Demo {    static void Main() {       DateTime myDate = new DateTime(2018, 9, 20);       Console.WriteLine(myDate.ToString("D", CultureInfo.CreateSpecificCulture("en-US")));    } }OutputThursday, September 20, 2018

A % in a format string would multiply a number by 100 before it is formatted.The percent symbol is added in the number at the location where the % appears.For an example, declare and initialize a double variable.double d = .045;Now, use % custom specifier to multiply number by 100.d.ToString("#0.##%", CultureInfo.InvariantCulture)Example Live Demousing System; using System.Globalization; class Demo {    static void Main() {       double d = .045;       Console.WriteLine(d.ToString("#0.##%", CultureInfo.InvariantCulture));       Console.WriteLine(String.Format(CultureInfo.InvariantCulture, "{0:#0.##%}", d));    } }Output4.5% 4.5%

Clear a LinkedList using Clear() method.Let us first set a LinkedList.string [] employees = {"Patrick", "Robert", "John", "Jacob", "Jamie"}; LinkedList list = new LinkedList(employees);Now, let us clear the LinkedList.list.Clear();Let us see the complete code.Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       string [] employees = {"Patrick", "Robert", "John", "Jacob", "Jamie"};       LinkedListlist = new LinkedList(employees);       foreach (var emp in list) {          Console.WriteLine(emp);       }       // clearing list       list.Clear();       Console.WriteLine("LinkedList after removing the ...

The Parse method in Enum converts the string representation of the name or numeric value of enum constants to an equivalent enumerated object.The following is our enumeration.enum Vehicle { Car, Bus, Truck, Motobike };Now, use the GetNames() method in a loop to get the enum values. Parse them using the Enum.Parse() method as shown below −Enum.Parse(typeof(Vehicle)Example Live Demousing System; public class Demo {    enum Vehicle { Car, Bus, Truck, Motobike };    public static void Main() {       Console.WriteLine("The enumeration...");       foreach (string v in Enum.GetNames(typeof(Vehicle))) {          Console.WriteLine("{0} = {1:D}", v, Enum.Parse(typeof(Vehicle), ... Read More

The ToString() method converts the value of this instance to its equivalent string representation.Firstly, set an enum.enum Vehicle { Car, Bus, Truck, Motobike };To convert it to an equivalent string representation, use ToString().Vehicle.Car.ToString("d")Example Live Demousing System; public class Demo {    enum Vehicle { Car, Bus, Truck, Motobike };    public static void Main() {       Console.WriteLine("Vehicle.Car = {0}", Vehicle.Car.ToString("d"));       Console.WriteLine("Vehicle.Bus = {0}", Vehicle.Bus.ToString("d"));    } }OutputVehicle.Car = 0 Vehicle.Bus = 1

The "d" format specifier represents a custom date and time format string.The format string is defined by culture's DateTimeFormatInfo.ShortDatePattern property.The custom format string is −MM/dd/yyyyExample Live Demousing System; using System.Globalization; class Demo {    static void Main() {       DateTime myDate = new DateTime(2018,9, 09);       Console.WriteLine(myDate.ToString("d", DateTimeFormatInfo.InvariantInfo));       Console.WriteLine(myDate.ToString("d", CultureInfo.CreateSpecificCulture("en-US")));    } }Output09/09/2018 9/9/2018

Use the Clear() method to clear a LinkedList. This will remove all the nodes from the LinkedList.Let’s say the following is our LinkedList −int [] num = {30, 65, 80, 95, 110, 135}; LinkedList list = new LinkedList(num);To clear the LinkedList.list.Clear();Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       int [] num = {30, 65, 80, 95, 110, 135};       LinkedList list = new LinkedList(num);       foreach (var n in list) {          Console.WriteLine(n);       }       // clear       list.Clear();       Console.WriteLine("No node in the LinkedList now...");       foreach (var n in list) {          Console.WriteLine(n);       }    } }Output30 65 80 95 110 135 No node in the LinkedList now...
