DateTime.Add() Method in C#
The DateTime.Add() method in C# is used to return a new DateTime that adds the value of the specified TimeSpan to the value of this instance.
Syntax
Following is the syntax −
public DateTime Add (TimeSpan val);
Above, Val is the positive or negative time interval.
Example
Let us now see an example to implement the DateTime.Add() method −
using System;
public class Demo {
public static void Main(){
DateTime d1 = new DateTime(2019, 3, 7, 8, 0, 15);
TimeSpan span = new TimeSpan(115, 0, 0, 0);
DateTime d2 = d1.Add(span);
System.Console.WriteLine("Initial DateTime = {0:y} {0:dd}", d1);
System.Console.WriteLine("
New DateTime = {0:y} {0:dd}", d2);
}
}Output
This will produce the following output −
Initial DateTime = March 2019 07 New DateTime = June 2019 30
Example
Let us now see another example to implement the DateTime.Add() method −
using System;
public class Demo {
public static void Main(){
DateTime d1 = new DateTime(2019, 9, 7, 8, 0, 15);
// subtracting days
TimeSpan span = new TimeSpan(-75, 0, 0, 0);
DateTime d2 = d1.Add(span);
System.Console.WriteLine("Initial DateTime = {0:y} {0:dd}", d1);
System.Console.WriteLine("
New DateTime = {0:y} {0:dd}", d2);
}
}Output
This will produce the following output −
Initial DateTime = September 2019 07 New DateTime = June 2019 24
