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}", ...
