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 ...

Convert a specified value to a 64-bit signed integer using Convert.ToInt64 Method.Let us take a double value.double doubleNum = 193.834;Now, convert it to Int64 i.e. long.long res; res = Convert.ToInt32(doubleNum);Example Live Demousing System; public class Demo {    public static void Main() {       double doubleNum = 193.834;       long res;       res = Convert.ToInt32(doubleNum);       Console.WriteLine("Converted {0} to {1}", doubleNum, res);    } }OutputConverted 193.834 to 194

Convert a specified value to an 8-bit signed integer i.e. SByte.It is a signed 8-bit integer data type which stores value between -128 to 127.Let us see an example. We have a double variable.double doubleNum = -19.9;Now, let us convert it to SByte.sbyte res; res = Convert.ToSByte(doubleNum);Example Live Demousing System; public class Demo {    public static void Main() {       double doubleNum = -19.9;       sbyte res;       res = Convert.ToSByte(doubleNum);       Console.WriteLine("Converted {0} to {1}", doubleNum, res);    } }OutputConverted -19.9 to -20

Use the Contains() method to check whether a node is a LinkedList or not.Here is our LinkedList.string [] students = {"Beth", "Jennifer", "Amy", "Vera"}; LinkedList list = new LinkedList(students);Now, to check whether the node “Amy” is in the list or not, we will use the Contains() method as shown below −list.Contains("Amy")The method will return a Boolean value i.e. True in this case.Let us see the complete code.Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       string [] students = {"Beth", "Jennifer", "Amy", "Vera"};       LinkedList list = new LinkedList(students);     ...

Use the Remove() method to remove the first occurrence of a node in a LinkedList.Firstly, let us set a LinkedList with integer elements.int [] num = {2, 5, 7, 15}; LinkedList list = new LinkedList(num);Now, let’s say you need to remove node with element 7. For that, use the Remove() method.list.Remove(7);Let us see the complete code.Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       int [] num = {2, 5, 7, 15};       LinkedList list = new LinkedList(num);       foreach (var n in list) {         ...
