本文探讨了在.NET框架中Volatile与VolatileRead/Write的区别。指出VolatileRead/Write方法使用全内存屏障，这在设计上是一个错误，并已被更正。推荐使用System.Threading.Volatile类，它在运行时会根据具体处理器类型替换为合适的版本。

Volatile vs VolatileRead/Write?

You should never use Thread.VolatileRead/Write(). It was a design mistake in .NET 1.1, it uses a full memory barrier. This was corrected in .NET 2.0, but they couldn't fix these methods anymore and had to add a new way to do it, provided by the System.Threading.Volatile class. Which is a class that the jitter is aware of, it replaces the methods at jit time with a version that's suitable for the specific processor type.
