Use the BufferWidth gets or sets the width of the buffer area.Use the property like this −Console.BufferWidthLet us see the complete example.Example Live Demousing System; class Demo {    static void Main() {       Console.WriteLine("Buffer width (columns) = "+Console.BufferWidth);    } }OutputBuffer width (columns) = 0

Reverse the elements in an array, using the Reverse method.Here is our character array.char[] ch = { 't', 'i', 'm', 'e' };Now use the Reverse() method with AsQueryable() method to get the reverse.ch.AsQueryable().Reverse();Let us see the complete code.Example Live Demousing System; using System.Linq; using System.Collections.Generic; public class Demo {    public static void Main() {       char[] ch = { 't', 'i', 'm', 'e' };       Console.Write("String = ");       foreach(char arr in ch) {          Console.Write(arr);       }       IQueryable res = ch.AsQueryable().Reverse();       Console.Write("Reversed String = ");       foreach (char c in res) {          Console.Write(c);       }    } }OutputString = time Reversed String = emit

The Full Date Long Time standard format specifier’s custom date and time format string is defined by the current DateTimeFormatInfo.FullDateTimePattern property.The custom format string is −dddd, dd MMMM yyyy HH:mm:ssExample Live Demousing System; using System.Globalization; class Demo {    static void Main() {       DateTime myDate = new DateTime(2018, 8, 13, 9, 15, 0);       Console.WriteLine(myDate.ToString("F", CultureInfo.CreateSpecificCulture("en-US")));    } }OutputMonday, August 13, 2018 9:15:00 AM

UShort represents a 16-bit unsigned integer.To implicitly convert of a 16-bit unsigned integer to a decimal, firstly set a ushort value.ushort val = 193;To convert ushort to decimal, assign the value.decimal dec; dec = val;Let us see an example.Exampleusing System; public class Demo {    public static void Main() {       ushort val = 2567;       decimal dec;       Console.WriteLine("Implicit conversion from 16-bit unsigned integer to Decimal");       dec = val;       Console.WriteLine("Decimal = "+dec);    } }

Use Orderby descending in C# to sort elements in descending order.The following is our list −IList emp = new List() { new Employee() { EmployeeRank = 3, EmpName = "Tom", EmpMarks = 90 } , new Employee() { EmployeeRank = 4, EmpName = "Katie", EmpMarks = 95 } };Now to sort the list according to Student name, use Orderby. The default is ascending, therefore for descending order, use descending.var res = from str in emp orderby str.EmpName descending select str;Here is the complete code.Example Live Demousing System; using System.Linq; using System.Collections.Generic; public class Demo {    public static void Main() { ...

To represent Int32 as a Octal string in C#, use the ToString() method and set the base as the ToString() method’s second parameter i.e. 8 for Octal.Int32 represents a 32-bit signed integer.Firstly, set an Int32 variable.int val = 99;Now, convert it to octal string by including 8 as the second parameter.Convert.ToString(val, 8)Example Live Demousing System; class Demo {    static void Main() {       int val = 99;       Console.WriteLine("Integer: "+val);       Console.Write("Octal String: "+Convert.ToString(val, 8));    } }OutputInteger: 99 Octal String: 143

The following is our list with elements −IList emp = new List() {    new Employee() { EmployeeRank = 4, EmpName = "Amit", EmpMarks = 90 } ,    new Employee() { EmployeeRank = 05, EmpName = "Raman", EmpMarks = 95 } };Now use orderby and descending to sort elements in descending order.var res = from str in emp orderby str.EmpName descending select str;Example Live Demousing System; using System.Linq; using System.Collections.Generic; public class Demo {    public static void Main() {       IList emp = new List() {          new Employee() { EmployeeRank = 4, EmpName ...

Get the minimum value from a sequence using the Min() method in C#.The following is our list.List list = new List { 1, 2, 3, 4, 5, 6 };Now, use Queryable Min() method to get minimum element.list.AsQueryable().Min();Exampleusing System; using System.Collections.Generic; using System.Linq; class Demo {    static void Main() {       List list = new List { 1, 2, 3, 4, 5, 6 };       foreach(long ele in list) {          Console.WriteLine(ele);       }       // getting lowest element       long min_num = list.AsQueryable().Min();       Console.WriteLine("Smallest number = {0}", mix_num);    } }

Get the maximum value from a sequence using the Max() method.Let’s say the following is our list.List list = new List { 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000 };Use the Max() method to get the largest element.list.AsQueryable().Max();Example Live Demousing System; using System.Collections.Generic; using System.Linq; class Demo {    static void Main() {       List list = new List { 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000 };       foreach(long ele in list)       Console.WriteLine(ele);       // getting largest element       long max_num = list.AsQueryable().Max();       Console.WriteLine("Largest number = {0}", max_num);    } }Output200 400 600 800 1000 1200 1400 1600 1800 2000 Largest number = 2000

AsQueryable() method is used to get an IQueryable reference.Let us see an example to find sum of integer values.Firstly, set an integer array.var arr = new int[] { 100, 200, 300, 400 };Now to find the sum, use the Queryable Sum() and AsQueryable() method.Queryable.Sum(arr.AsQueryable());The following is the complete code.Example Live Demousing System; using System.Linq; class Demo {    static void Main() {       var arr = new int[] { 100, 200, 300, 400 };       int res = Queryable.Sum(arr.AsQueryable());       Console.WriteLine("Sum: "+res);    } }OutputSum: 1000
