是Stopwatch.ElapsedTicks线程？ [英] Is Stopwatch.ElapsedTicks threadsafe?

问题描述

如果我有一个共同的 System.Diagnostics.Stopwatch 例如，可以将多个线程调用 shared.ElapsedTicks 在安全的方式，并得到准确的结果？

If I have a shared System.Diagnostics.Stopwatch instance, can multiple threads call shared.ElapsedTicks in a safe manner and get accurate results?

有没有线程安全方面的任何区别/用秒表的共享实例以这种方式，而使用静态的精度 GetTimeStamp（）方法？

Is there any difference in terms of thread-safety/accuracy between using a shared instance of Stopwatch in this way, and using the static GetTimeStamp() method?

我测量周围180ms的时间间隔，并发现使用共享实例给我更大的成果传播，包括那些比我矮所期望的显著数量。

I'm measuring intervals of around 180ms, and finding that using the shared instance is giving me a larger spread of results, including a significant number that are shorter than I would expect.

本机具有多个CPU（2 *英特尔X5550为它的价值）

The machine has multiple CPUs (2 * Intel X5550 for what it's worth)

推荐答案

从的 MSDN 的：任何实例成员不能保证是线程安全的

From MSDN: "Any instance members are not guaranteed to be thread safe."
