问题描述
在javascrip中
in javascrip
var d = new Date();
var n = d.getTime();
how in c#?
推荐答案
DateTime baseDate = new DateTime(1970, 1, 1);
TimeSpan diff = DateTime.Now - baseDate;
Console.WriteLine(diff.TotalMilliseconds);
Milliseconds属性仅给出TimeSpan的毫秒分量(总计年，天，小时，分钟和秒的数量后剩余的数量)，而TotalMilliseconds给出的总毫秒数由值.
The Milliseconds property just gives the milliseconds component of the TimeSpan (the amount left-over after totaling the number of years, days, hours, minutes and seconds), while TotalMilliseconds gives the total number of milliseconds represented by the value.
DateTime baseDate = new DateTime(1970, 1, 1);
TimeSpan diff = DateTime.Now - baseDate;
Console.WriteLine(diff.Milliseconds);
