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) {         ...

The following is our array −int[] points = { 210, 250, 300, 350, 420};Use skip() method to skip elements. Add the number as an argument that displays the number of elements to be returned.IEnumerable skipEle = points.AsQueryable().OrderByDescending(s => s).Skip(3);Example Live Demousing System; using System.Linq; using System.Collections.Generic; public class Demo {    public static void Main() {       int[] points = { 210, 250, 300, 350, 420};       Console.WriteLine("Initial array...");           foreach (int res in points)       Console.WriteLine(res);       IEnumerable skipEle = points.AsQueryable().OrderByDescending(s => s).Skip(3);       Console.WriteLine("Skipped 3 elements...");       foreach (int res in skipEle)       Console.WriteLine(res);    } }OutputInitial array... 210 250 300 350 420 Skipped 3 elements... 250 210

Set a LinkedList.int [] num = {1, 2, 3, 4, 5}; LinkedList list = new LinkedList(num);Now add a node at the end using AddLast() method.var newNode = list.AddLast(20);To add a node after the above added node, use the AddAfter() method.list.AddAfter(newNode, 30);Example Live Demousing System; using System.Collections.Generic; class Demo {    static void Main() {       int [] num = {1, 2, 3, 4, 5};       LinkedList list = new LinkedList(num);       foreach (var n in list) {          Console.WriteLine(n);       }       // adding a node at the ...

The ulong type represents a 64-bit unsigned integer i.e. UInt64.To implicitly convert a 64-bit unsigned integer to a Decimal, firstly set UInt64 value.ulong val = ulong.MaxValue;To convert ulong to decimal, assign the value.decimal dec; dec = val;Let us see the above example.Example Live Demousing System; public class Demo {    public static void Main() {       ulong val = ulong.MaxValue;       decimal dec;       Console.WriteLine("Implicit conversion from Ulong to Decimal");       dec = val;       Console.WriteLine("Decimal : "+dec);    } }OutputImplicit conversion from Ulong to Decimal Decimal : 18446744073709551615

Use Convert.ToInt32 method to convert text to an integer.Firstly, set a string.string str = "12";Now, use the Convert.ToInt32() method the above string to number.Convert.ToInt32(str);Let us see the complete example.Example Live Demousing System; class Program {    static void Main() {       string str = "12";       Console.WriteLine("String: "+str);       int n = Convert.ToInt32(str);       Console.WriteLine("Number: "+n);    } }OutputString: 12 Number: 12
