c# - ArrayPool.Rent(Int32) 方法是线程安全的吗？

Question

我刚刚发现 ArrayPool 的存在，但它的文档有点缺乏。

我想知道 Rent(.)和 Return(.)是线程安全的。

编辑:看起来我没有注意到文档的“线程安全”部分；但阅读了一些评论和答案后，我松了一口气，我不是唯一没有这样做的人。

更新来自 ta.speot.is 的评论

It literally says on Thread safety This class is thread-safe. All members may be used by multiple threads concurrently

原创

learn.microsoft.com 上没有这样说，但是有一些引用资料表明它是这样的

Add a new System.Buffers namespace to the BCL for Resource Pooling

The Pool will be lightweight and thread-safe, allowing for fast Rent and Return calls from any thread within the process, along with minimal locking overhead, and 0 heap allocations on most Rent calls (exceptions to this will be called out below in the description of the Rent function).

Pooling large arrays with ArrayPool

Recommended: use the ArrayPool.Shared property, which returns a shared pool instance. It’s thread safe and all you need to remember is that it has a default max array length, equal to 2^20 (1024*1024 = 1 048 576).
