如何在C#中找到当前时间长？

Question

我有这个Java代码,我想在C#中做同样的事情:

long now =System.currentTimeMillis()/1000;

Answer 1

检查了java返回的内容(1970/1/1等):

static readonly DateTime epoch=new DateTime(1970,1,1,0,0,0,DateTimeKind.Utc);
...
long ms = (long)(DateTime.UtcNow - epoch).TotalMilliseconds;
long result = ms / 1000;
