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), ...

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...

SByte represents an 8-bit signed integer.To implicitly convert an 8-bit signed integer to a Decimal, firstly set an sbyte value.sbyte val = 51;To convert sbyte to decimal, assign the value.decimal d; d = val;Let us see another example.Exampleusing System; public class Demo { public static void Main() { sbyte val = 39; decimal d; Console.WriteLine("Implicit conversion from 8-bit signed integer (sbyte) to Decimal"); d = val; Console.WriteLine("Decimal = "+dec); } }

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); } }
