In this article, we will learn how to convert DateTime to UnixTimeStamp in C#.
Unix time is the number of seconds since 1st January 1970, 00:00:00 UTC. Before .Net 4.6, we used this way to convert Datetime To UnixTimeStamp as follows:
using System;
namespace Tutorialsrack
{
class Program
{
/* How to Convert DateTime To UnixTimeStamp in C# */
static void Main(string[] args)
{
Console.Write("Unix Time Stamp: ");
Console.WriteLine(ConvertDatetimeToUnixTimeStamp(DateTime.Now));
//Hit ENTER to exit the program
Console.ReadKey();
}
public static long ConvertDatetimeToUnixTimeStamp(DateTime date)
{
DateTime originDate = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
TimeSpan diff = date.ToUniversalTime() - originDate;
return (long)Math.Floor(diff.TotalSeconds);
}
}
}
After .NET 4.6, some new methods were added, but to use them, you’ll first have to convert from DateTime to DateTimeOffset. First, make sure you’re targeting the right version of the .NET Framework. Here is the method to convert to DateTime to UnixTimeStamp as follow:
using System;
namespace Tutorialsrack
{
class Program
{
/* How to Convert DateTime To UnixTimeStamp in C# */
///
/// In This Program, We will Convert Datetime
/// To unixTimeStamp by using built in methods
/// provided in .Net 4.6
///
///
static void Main(string[] args)
{
Console.Write("Unix Time Stamp: ");
Console.WriteLine(ConvertDatetimeToUnixTimeStamp(DateTime.Now));
//Hit ENTER to exit the program
Console.ReadKey();
}
public static long ConvertDatetimeToUnixTimeStamp(DateTime date)
{
var dateTimeOffset = new DateTimeOffset(date);
var unixDateTime = dateTimeOffset.ToUnixTimeSeconds();
return unixDateTime;
}
}
}I hope this article will help you to understand how to convert DateTime to UnixTimeStamp in C#.
