The Tuple class represents a 1-tuple, which is called singleton. A tuple is a data structure that has a sequence of elements.ExampleLet us now see an example to implement the 1-tuple in C# −using System; public class Demo { public static void Main(string[] args) { Tuple tuple = new Tuple(100); Console.WriteLine("Value = " + tuple.Item1); if (tuple.Item1 == 150) { Console.WriteLine(tuple.Item1); } if (tuple.Item1 == 100) { Console.WriteLine(tuple.Item1); } } }OutputThis will ...

The DateTimeOffset.FromUnixTimeSeconds() method in C# is used to convert a Unix time expressed as the number of seconds that have elapsed since 1970-01-01T00:00:00Z to a DateTimeOffset value.SyntaxFollowing is the syntax −public static DateTimeOffset FromUnixTimeSeconds (long val);Above, the parameter value is a Unix time, expressed as the number of seconds that have elapsed since 1970-01-01T00:00:00Z (January 1, 1970, at 12:00 AM UTC).ExampleLet us now see an example to implement the DateTimeOffset.FromUnixTimeSeconds() method −using System; public class Demo { public static void Main() { DateTimeOffset offset = DateTimeOffset.FromUnixTimeSeconds(20); Console.WriteLine("DateTimeOffset = {0} ", offset); ... Read More
The DateTimeOffset.FromUnixTimeMilliseconds() method in C# is used to convert a Unix time expressed as the number of milliseconds that have elapsed since 1970-01-01T00:00:00Z to a DateTimeOffset value.SyntaxFollowing is the syntax −public static DateTimeOffset FromUnixTimeMilliseconds (long val);Above, Val are the milliseconds that have elapsed since 1970-01-01T00:00:00Z (January 1, 1970, at 12:00 AM UTC).ExampleLet us now see an example to implement the DateTimeOffset.FromUnixTimeMilliseconds() method −using System; public class Demo { public static void Main() { DateTimeOffset offset = DateTimeOffset.FromUnixTimeMilliseconds(30000); Console.WriteLine("DateTimeOffset = {0} ", offset); Console.WriteLine("DateTimeOffset (other format) = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ", ...

The DateTime.AddYears() method in C# is used to add the specified number of years to the value of this instance. It returns new DateTime.SyntaxFollowing is the syntax −public DateTime AddYears (int yrs);Above, yrs are the years to be added. If you want to subtract years, then use a negative value.ExampleLet us now see an example to implement the DateTime.AddYears() method −using System; public class Demo { public static void Main(){ DateTime d1 = new DateTime(2019, 11, 20, 6, 20, 40); DateTime d2 = d1.AddYears(5); Console.WriteLine("Initial DateTime = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ...
