In this article, you 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.

 

Int32 unixTimestamp = (Int32)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds;

 

using System;

namespace usingcsharp
{
    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));

            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);
        }
    }
}

 

public long UnixTimeNow()
{
    var timeSpan = (DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0));
    return (long)timeSpan.TotalSeconds;
}

 

using System;

namespace usingcsharp
{
    class Program
    {
        /* How to Convert DateTime To UnixTimeStamp in C# */        
         /// provided in .Net 4.6

        {
            Console.Write("Unix Time Stamp: ");
            Console.WriteLine(ConvertDatetimeToUnixTimeStamp(DateTime.Now));

            Console.ReadKey();
        }

            var dateTimeOffset = new DateTimeOffset(date);

How To Convert DateTime To UnixTimeStamp in C#
C# is a programming language developed by Microsoft that runs on the .NET Framework. C# is used to develop web, desktop, mobile, games and much more application. C# is a object-oriented programming language developed by Microsoft within its .NET Framework. Led by Anders Hejlsberg, your basic C# programming and will also take you through various advanced concepts related to C# programming language. C# such as control statements, objects and classes, inheritance, constructor, destructor, this, static, sealed, polymorphism, abstraction, abstract class, interface, File IO, Collections, namespace, encapsulation, properties, indexer, arrays, strings, regex, exception handling, multithreading etc. For example... using System; namespace MinifyCode { class Program { static void Main(string[] args) { Console.WriteLine("Hello Minify Code"); } } } Output: Hello Minify Code In this article you will learn, what is server side controls. We will discuss each of these objects in due time. In this tutorial we will explore the Server object, the Request object, and the Response object. Session Application Cache Request Response Server User Trace Server Object The Server object in Asp.NET is an instance of the System.Web.HttpServerUtility class. The HttpServerUtility class provides numerous properties and methods to perform many type of jobs. Methods and Properties of the Server object The methods and properties of the HttpServerUtility class are exposed through the intrinsic Server object provided by ASP.NET. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Optimization; using System.Web.Routing; using System.Web.Security; using System.Web.SessionState; using System.Data.Entity; namespace minifycode { public class Global : HttpApplication { void Application_Start(object sender, EventArgs e) { // Code that runs on application startup RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); // Initialize the product database.
