Below program shows how we can print the current date and time in different date time formats in C#?

using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            //Get current date and time using .Now property
            DateTime dt = DateTime.Now;

            //Now we print all possible date and time formates.
            Console.WriteLine(dt.ToString("yyyy MMMM"));
            Console.WriteLine(dt.ToString("HH:mm:ss"));
            Console.WriteLine(dt.ToString("h:mm tt"));
            Console.WriteLine(dt.ToString("H:mm"));
            Console.WriteLine(dt.ToString("hh:mm tt"));
            Console.WriteLine(dt.ToString("HH:mm"));
            Console.WriteLine(dt.ToString("ddd, dd MMM yyy HH':'mm':'ss 'GMT'"));
            Console.WriteLine(dt.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss"));  
            Console.WriteLine(dt.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss.fffffffK"));
            Console.WriteLine(dt.ToString("MMMM dd"));
            Console.WriteLine(dt.ToString("MM/dd/yyyy HH:mm:ss"));
            Console.WriteLine(dt.ToString("MM/dd/yyyy h:mm tt"));
            Console.WriteLine(dt.ToString("MM/dd/yyyy H:mm"));
            Console.WriteLine(dt.ToString("MM/dd/yyyy HH:mm"));
            Console.WriteLine(dt.ToString("dddd, dd MMMM yyyy HH:mm:ss"));
            Console.WriteLine(dt.ToString("dddd, dd MMMM yyyy"));
            Console.WriteLine(dt.ToString("MM/dd/yyyy"));
            Console.WriteLine(dt.ToString("dddd, dd MMMM yyyy")); 
            Console.WriteLine(dt.ToString("MM/dd/yyyy hh:mm tt"));
            
            Console.WriteLine();  
        }
    }
}
