c# - 保证信号量顺序？

Question

documentation对于 .NET Semaphore 类声明:

There is no guaranteed order, such as FIFO or LIFO, in which blocked threads enter the semaphore.

在这种情况下，如果我想要保证订单(先进先出或后进先出)，我有哪些选择？这是不容易做到的事情吗？我必须编写自己的信号量吗？我认为那会非常先进？

谢谢，

参见 this :

The FifoSemaphore works exactly like a normal Semaphore but also guarantees that tokens are served out to acquirers in the order that they manage to acquire the internal lock. The usage of a FifoSemaphore is identical to a Semaphore.
