最后的结论就是,如果想用 .NET 的 System.DateTime.Now.Ticks 来实现 Java 的 java.util.Calendar.getInstance().getTimeInMillis() 的话,你可以采取类似“(DateTime.Now.Ticks - new DateTime(1970, 1, 1).Ticks) / 10000”的办法,当然,我是用的“(DateTime.Now.Ticks - 621355968000000000) / 10000”,一...

一、gettimeinmillis是什么 在Java中，System类中提供了一个静态方法System.currentTimeMillis()来获取当前系统时间的毫秒数。这个方法可以用于计算程序的运行时间或者记录事件的发生时间等。二、Java中的gettimeinmillis的用法 在Java中，gettimeinmillis主要通过System.currentTimeMillis()方法来实现。该方法返回自1970年...
