Adding months to a date in C#

  1. Forget Code
  2. C#
  3. Adding months to a date
We can add months to a date like below.
C# will take care of year when you add the months since it adheres to universal date and time rules.
The day will remain same.

  1. using System;
  2.  
  3. namespace forgetCode
  4. {
  5.     class Program
  6.     {
  7.         static void Main(string[] args)
  8.         {
  9.  
  10.             Console.WriteLine("Enter year in the format dd-mm-yyyy");
  11.             DateTime dt = Convert.ToDateTime(Console.ReadLine());
  12.  
  13.             Console.WriteLine("Enter the months to add :");
  14.             int months = Convert.ToInt32(Console.ReadLine());
  15.  
  16.             DateTime newDate = dt.AddMonths(months);
  17.             Console.WriteLine(newDate.ToShortDateString());
  18.        
  19.             
  20.         }
  21.  
  22.     }
