Set two dates.DateTime date1 = new DateTime(2018, 7, 15, 08, 15, 20); DateTime date2 = new DateTime(2018, 8, 17, 11, 14, 25);Now, get the difference between two dates.TimeSpan ts = date2 - date1;Get the result i.e. the difference in hours.ts.TotalHoursLet us see the complete code.Example Live Demousing System; using System.Linq; public class Demo { public static void Main() { DateTime date1 = new DateTime(2018, 7, 15, 08, 15, 20); DateTime date2 = new DateTime(2018, 8, 17, 11, 14, 25); TimeSpan ts = date2 - date1; Console.WriteLine("No. of Hours (Difference) = {0}", ts.TotalHours); } }OutputNo. of Hours (Difference) = 794.984722222222

The percent ("P") format specifier is used to multiply a number by 100.It converts the number into a string representing a % (percentage).We have the following double type −double val = .975746;If we will set (“P”) format specifier, then the above would result as −97.57 %In the same way, using (“P1”), would only include a single vale after decimal-point.97.6%Example Live Demousing System; using System.Globalization; class Demo { static void Main() { double val = .975746; Console.WriteLine(val.ToString("P", CultureInfo.InvariantCulture)); Console.WriteLine(val.ToString("P1", CultureInfo.InvariantCulture)); Console.WriteLine(val.ToString("P4", CultureInfo.InvariantCulture)); } }Output97.57 % 97.6 % 97.5746 %

The ("F") format specifier converts a number to a string of the following form −"-ddd.ddd…"Above, "d" indicates a digit (0-9).Let us see an example.Here, if we will set (“F3”) format specifier to add three values after decimal places, for let’s say, 212.212.000The following is another example −Example Live Demousing System; using System.Globalization; class Demo { static void Main() { int val; val = 38788; Console.WriteLine(val.ToString("F",CultureInfo.InvariantCulture)); val = -344; Console.WriteLine(val.ToString("F3",CultureInfo.InvariantCulture)); val = 5656; Console.WriteLine(val.ToString("F5",CultureInfo.InvariantCulture)); } }Output38788.00 -344.000 5656.00000

The ("E") format specifier converts a number to a string of the following form −"-d.ddd…E+ddd"Or"-d.ddd…e+ddd"Above, "d" is a digit (0-9).Prefix the exponent with an "E" or an "e".Example Live Demousing System; using System.Globalization; class Demo { static void Main() { double d = 3452.7678; Console.WriteLine(d.ToString("E", CultureInfo.InvariantCulture)); Console.WriteLine(d.ToString("E10", CultureInfo.InvariantCulture)); Console.WriteLine(d.ToString("e", CultureInfo.InvariantCulture)); Console.WriteLine(d.ToString("e10", CultureInfo.InvariantCulture)); } }Output3.452768E+003 3.4527678000E+003 3.452768e+003 3.4527678000e+003

The long type represents a 64-bit signed integer.To implicitly convert a 64-bit signed integer to a Decimal, firstly set a long value.long val = 989678876876876;To convert long to decimal, assign the value.dec = val;Let us see another example −Example Live Demousing System; public class Demo { public static void Main() { long val = 76755565656565; decimal dec; Console.WriteLine("Implicit conversion from 64-bit signed integer (long) to Decimal"); dec = val; Console.WriteLine("Decimal : "+dec); } }OutputImplicit conversion from 64-bit signed integer (long) to Decimal Decimal : 76755565656565

Use the SkipWhile() method to skip elements from a sequence as long as the specified condition is true.The following is the array −int[] marks = { 35, 42, 48, 88, 55, 90, 95, 85 };Here is the condition.s => s >= 50As long as the above condition is true, the elements above 50 are skipped as shown below −Example Live Demousing System; using System.Linq; using System.Collections.Generic; public class Demo { public static void Main() { int[] marks = { 35, 42, 48, 88, 55, 90, 95, 85 }; // skips elements above 50 IEnumerable selMarks = marks.AsQueryable().OrderByDescending(s => s).SkipWhile(s => s >= 50); // displays rest of the elements Console.WriteLine("Skipped marks > 60..."); foreach (int res in selMarks) { Console.WriteLine(res); } } }OutputSkipped marks > 60... 48 42 35

Declare an array and initialize elements.int[] marks = { 45, 50, 60, 70, 85 };Use the SkipLast() method to skip elements of an array from the end.IEnumerable selMarks = marks.AsQueryable().SkipLast(3);The elements are skipped and rest of the elements is returned as shown below −Example Live Demousing System; using System.Linq; using System.Collections.Generic; public class Demo { public static void Main() { int[] marks = { 45, 50, 60, 70, 85 }; Console.WriteLine("Array..."); foreach (int res in marks) Console.WriteLine(res); IEnumerable selMarks = marks.AsQueryable().SkipLast(3); Console.WriteLine("Array after skipping last 3 elements..."); foreach (int res in selMarks) Console.WriteLine(res); } }OutputArray... 45 50 60 70 85 Array after skipping last 3 elements... 45 50

Firstly, get the current date.DateTime.TodayNow, use AddDays() method to add days to the current date. Here, we are adding 10 days to the current date.DateTime.Today.AddDays(10)Let us see the complete code −Example Live Demousing System; using System.Linq; public class Demo { public static void Main() { Console.WriteLine("Today = {0}", DateTime.Today); Console.WriteLine("Add 10 Days = {0}", DateTime.Today.AddDays(10)); } }OutputToday = 9/11/2018 12:00:00 AM Add 10 Days = 9/21/2018 12:00:00 AM

Convert a specified value to a single-precision floating-point number using the Convert.ToSingle() method in C#.Here is our bool −bool boolVal = false;Now, let us use the ToSingle() method to convert the value to a single precision floating-point.float floatVal; floatVal = Convert.ToSingle(boolVal);Example Live Demousing System; public class Demo { public static void Main() { bool boolVal = false; float floatVal; floatVal = Convert.ToSingle(boolVal); Console.WriteLine("Converted {0} to {1}", boolVal, floatVal); } }OutputConverted False to 0

The Full Date Short Time standard format specifier represents a combination of the long date ("D") and short time ("t") patterns.UseDateTime to set the date.DateTime myDate = new DateTime(2018, 8, 29, 1, 10, 0);Now, use the (“f”) format specifier like this −myDate.ToString("f", CultureInfo.CreateSpecificCulture("en-US"))The following is an example −Example Live Demousing System; using System.Globalization; class Demo { static void Main() { DateTime myDate = new DateTime(2018, 8, 29, 1, 10, 0); Console.WriteLine(myDate.ToString("f",CultureInfo.CreateSpecificCulture("en-US"))); } }OutputWednesday, August 29, 2018 1:10 AM
