本篇文章主要介绍了C# DateTime与时间戳转换实例,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧

C# DateTime与时间戳的相互转换,包括JavaScript时间戳和Unix的时间戳。

1. 什么是时间戳

首先要清楚JavaScript与Unix的时间戳的区别:

JavaScript时间戳:是指格林威治时间1970年01月01日00时00分00秒(北京时间1970年01月01日08时00分00秒)起至现在的总毫秒数。

Unix时间戳:是指格林威治时间1970年01月01日00时00分00秒(北京时间1970年01月01日08时00分00秒)起至现在的总秒数。

可以看出JavaScript时间戳总毫秒数,Unix时间戳是总秒数。

比如同样是的 2016/11/03 12:30:00 ,转换为JavaScript时间戳为 1478147400000;转换为Unix时间戳为 1478147400。

2. JavaScript时间戳相互转换

2.1 C# DateTime转换为JavaScript时间戳

System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1)); // 当地时区

long timeStamp = (long)(DateTime.Now - startTime).TotalMilliseconds; // 相差毫秒数

System.Console.WriteLine(timeStamp);
Copy after login

2.2 JavaScript时间戳转换为C# DateTime


long jsTimeStamp = 1478169023479;

System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1)); // 当地时区

DateTime dt = startTime.AddMilliseconds(jsTimeStamp);

System.Console.WriteLine(dt.ToString("yyyy/MM/dd HH:mm:ss:ffff"));
Copy after login

3. Unix时间戳相互转换

3.1 C# DateTime转换为Unix时间戳


System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1)); // 当地时区

long timeStamp = (long)(DateTime.Now - startTime).TotalSeconds; // 相差秒数

System.Console.WriteLine(timeStamp);
Copy after login

3.2 Unix时间戳转换为C# DateTime


long unixTimeStamp = 1478162177;

System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1)); // 当地时区

DateTime dt = startTime.AddSeconds(unixTimeStamp);

System.Console.WriteLine(dt.ToString("yyyy/MM/dd HH:mm:ss:ffff"));
Copy after login
