C#: Add millisecond to a given date

Last update on December 20 2024 12:48:54 (UTC/GMT +8 hours)

Write a C# Sharp Program to add one millisecond and 2.5 milliseconds to a given date value. Display each value and the difference between it and the original value.

Note: The difference is displayed both as a time span and as a number of ticks and one millisecond equals 10,000 ticks.

Sample Solution:-

C# Sharp Code:

using System;

public class Example12
{
    // Main method, entry point of the program
    public static void Main()
    {
        // Date format string for displaying dates with milliseconds
        string dateFormat = "MM/dd/yyyy hh:mm:ss.fffffff";

        // Create a DateTime object 'date1' set to August 16, 2016, 4:00:00 PM
        DateTime date1 = new DateTime(2016, 8, 16, 16, 0, 0);
        Console.WriteLine("Original date: {0} ({1:N0} ticks)\n",
                          date1.ToString(dateFormat), date1.Ticks);

        // Create 'date2' by adding 1 millisecond to 'date1'
        DateTime date2 = date1.AddMilliseconds(1);
        Console.WriteLine("Second date:   {0} ({1:N0} ticks)",
                          date2.ToString(dateFormat), date2.Ticks);
        Console.WriteLine("Difference between dates: {0} ({1:N0} ticks)\n",
                          date2 - date1, date2.Ticks - date1.Ticks);

        // Create 'date3' by adding 2.5 milliseconds to 'date1' 
        DateTime date3 = date1.AddMilliseconds(2.5);
        Console.WriteLine("Third date:    {0} ({1:N0} ticks)",
                          date3.ToString(dateFormat), date3.Ticks);
        Console.WriteLine("Difference between dates: {0} ({1:N0} ticks)",
                          date3 - date1, date3.Ticks - date1.Ticks);
    }
}

Sample Output:

Original date: 08/16/2016 04:00:00.0000000 (636,069,600,000,000,000 ticks)             
                                                                                       
Second date:   08/16/2016 04:00:00.0010000 (636,069,600,000,010,000 ticks)             
Difference between dates: 00:00:00.0010000 (10,000 ticks)                              
                                                                                       
Third date:    08/16/2016 04:00:00.0030000 (636,069,600,000,030,000 ticks)             
Difference between dates: 00:00:00.0030000 (30,000 ticks)
