ASP.NET：获取毫秒，因为1/1/1970 [英] ASP.NET: Get milliseconds since 1/1/1970

问题描述

我有一个ASP.NET，VB.NET日期，而我试图让毫秒数自1月1日，1970年我试图寻找在MSDN的方法，但我无法找到任何东西。有谁知道如何做到这一点？

I have an ASP.NET, VB.NET Date, and I'm trying to get the number of milliseconds since January 1st, 1970. I tried looking for a method in MSDN, but I couldn't find anything. Does anyone know how to do this?

推荐答案

您可以减去任何两个的DateTime 实例，并获得时间跨度和 TotalMilliseconds 会给你总毫秒。 。下面的示例

You can subtract any two DateTime instances and get TimeSpan and TotalMilliseconds would give you total milliseconds. Sample below.

    DateTime dt1970 = new DateTime(1970, 1, 1);
    DateTime current = DateTime.Now;
    TimeSpan span = current - dt1970;
    Console.WriteLine(span.TotalMilliseconds.ToString());

单行

//DateTime.MinValue is 01/01/01 00:00 so add 1969 years. to get 1/1/1970
DateTime.Now.Subtract(DateTime.MinValue.AddYears(1969)).TotalMilliseconds;
