The Tuple class represents a 4-tuple, which is called quadruple. A tuple is a data structure that has a sequence of elements.It is used in −Easier access to a data set.Easier manipulation of a data set.To represent a single set of data.To return multiple values from a methodTo pass multiple values to a methodExampleLet us now see an example to implement the 4-tuple in C# −using System; public class Demo { public static void Main(string[] args) { Tuple tuple = new Tuple("nathan", "steve", "katie", "tim"); Console.WriteLine("Value (Item1)= " + tuple.Item1); ...

The DateTimeOffset.Compare() method in C# is used to compare two DateTimeOffset objects and indicates whether the first is earlier than the second, equal to the second, or later than the second. It returns an integer value, 0 − If val1 is later than val2SyntaxFollowing is the syntax −public static int Compare (DateTimeOffset val1, DateTimeOffset val1);Above, val1 is the 1st object to compare, whereas val2 is the 2nd.ExampleLet us now see an example to implement the DateTimeOffset.Compare() method −using System; public class Demo { public static void Main() { DateTimeOffset dateTimeOffset1 = new DateTimeOffset(2019, 09, 09, 8, ... Read More
The DateTimeOffset.AddYears() method in C# is used to add a specified number of years to the value of this instance.SyntaxFollowing is the syntax −public DateTimeOffset AddYears (int val);Above, the Val parameter is the years to be added to the offset. To subtract, you need to set negative values.ExampleLet us now see an example to implement the DateTimeOffset.AddYears() method −using System; public class Demo { public static void Main() { DateTimeOffset dateTimeOffset = new DateTimeOffset(2019, 06, 09, 8, 20, 10, new TimeSpan(-5, 0, 0)); Console.WriteLine("DateTimeOffset (before adding years) = {0}", dateTimeOffset); ...

Dictionary in C# is a collection of keys and values. It is a generic collection class in the System.Collection.Generics namespace.SyntaxFollowing is the syntax −public class DictionaryAbove, the key parameter is the type of keys in the dictionary, whereas TValue is the type of values.ExampleLet us now create a Dictionary and add some elements −using System; using System.Collections.Generic; public class Demo { public static void Main(){ Dictionary dict = new Dictionary(); dict.Add("One", "John"); dict.Add("Two", "Tom"); dict.Add("Three", "Jacob"); dict.Add("Four", "Kevin"); dict.Add("Five", "Nathan"); ...

The Convert.ToSByte() method in C# converts the specified string representation of a number to an equivalent 8-bit signed integer, using the specified culture-specific formatting information.SyntaxFollowing is the syntax −public static sbyte ToSByte (string val, IFormatProvider provider);Above, the parameter value is a string that contains the number to convert. A provider parameter is an object that supplies culture-specific formatting information.ExampleLet us now see an example to implement the Convert.ToSByte() method −using System; using System.Globalization; public class Demo { public static void Main(){ CultureInfo cultures = new CultureInfo("en-US"); String str = "-2"; ... Read More
The Convert.ToDouble() method in C# converts the specified string representation of a number to an equivalent double-precision floating-point number, using the specified culture-specific formatting information.SyntaxFollowing is the syntax −public static double ToDouble (string val, IFormatProvider provider);Above, the value value is a string that contains the number to convert, whereas the provider is an object that supplies culture-specific formatting information.ExampleLet us now see an example to implement the Convert.ToDouble() method −using System; using System.Globalization; public class Demo { public static void Main(){ String val = "876876, 878"; NumberFormatInfo formatProvider = new NumberFormatInfo(); ...

The DateTime.AddHours() method in C# is used to add the specified number of hours to the value of this instance. This method returns a new DateTime.SyntaxFollowing is the syntax −public DateTime AddHours (double hrs);Above, hrs are the number of hours to be added. The value can be negative to subtract the hours.ExampleLet us now see an example to implement the DateTime.AddHours() methodusing System; public class Demo { public static void Main(){ DateTime d1 = new DateTime(2019, 11, 2, 9, 0, 10); DateTime d2 = d1.AddHours(2); System.Console.WriteLine("Initial DateTime = {0:dd} {0:y}, ... Read More
The DateTime.AddDays() method in C# is used to add the specified number of days to the value of this instance. This method returns a new DateTime.SyntaxFollowing is the syntax −public DateTime AddDays (double days);Above, the parameter days are the number of days to be added. To subtract, add a negative value.ExampleLet us now see an example to implement the DateTime.AddDays() method −using System; public class Demo { public static void Main(){ DateTime d1 = new DateTime(2019, 11, 2, 8, 0, 15); DateTime d2 = d1.AddDays(25); System.Console.WriteLine("Initial DateTime = {0:y} {0:dd}", ...
