是C＃基本数组动荡？ [英] are c# primitive arrays volatile?

问题描述

我声明数组一样，私人双[]数组=新的双[长度] 。它是安全的在一个线程中更新此数组项，并在另一个线程读取？我是否有最新的价值？

I declare array like that private double[] array = new double[length]. Is it safe to update this array items in one thread and read in another thread? Will I have up to date value?

请注意，我不一一列举数组。我只按索引访问它的项目。

Note i do not enumerate array. I only access its items by index.

推荐答案

挥发性不保证值的新鲜感。它可以防止一些优化，但不保证线程同步。

Volatile does not guarantee freshness of a value. It prevents some optimizations, but does not guarantee thread synchronization.

双击不guaranted是的更新原子。因此，更新/阅读双打的阵列，而不同步将不会在所有的智慧或不挥发，你可以阅读部分写入的值是线程安全的。

Double is not guaranted to be updated atomically. So updating/reading arrays of doubles without synchronization will not be thread safe at all wit or without volatile as you may read partially written values.
