How do i get from Stopwatch.GetTimestamp() to a DateTime

假设Stopwatch.IsHighResolution是真的

Assume Stopwatch.IsHighResolution is true

推荐答案

如果它是一个高分辨率计数器，不能保证该值与实时有任何关联 - 例如，它可能是从计算机启动时刻录。对于非 - 高分辨率计时器，您可以使用新的DateTime（Stopwatch.GetTimestamp（）），但这不一定会给出有用的值用于高分辨率定时器。 （这当然不在我的盒子上。）

If it's a high resolution counter, there's no guarantee that the value has any correlation with the real time - for example, it may well be "ticks since the computer booted." For a non-high resolution timer, you could use new DateTime(Stopwatch.GetTimestamp()) but that won't necessarily give a useful value for a high resolution timer. (It certainly doesn't on my box.)

你想用什么？ Stopwatch 的想法是测量时间的间隔。

What are you trying to use this for? The idea of Stopwatch is to measure intervals of time.
