推荐答案

您应该MSDN开始。

• 的 System.Threading.Mutex ：一个同步原语，可以也可以用于进程间同步


• 的System.Threading.Semaphore ：限制可以访问资源的资源或池的线程数同时进行的。

• System.Threading.Mutex: A synchronization primitive that can also be used for interprocess synchronization.
• System.Threading.Semaphore: Limits the number of threads that can access a resource or pool of resources concurrently.

一般只使用一个互斥跨进程，如如果你有多个应用程序必须共享，或者如果你想建立一个单一实例化的应用程序（即只允许1份在同一时间运行）的资源。

Generally you only use a Mutex across processes, e.g. if you have a resource that multiple applications must share, or if you want to build a single-instanced app (i.e. only allow 1 copy to be running at one time).

信号量可以限制访问并发线程的具体数量，这样你可以有，例如，最多两个线程同时执行特定的代码路径。

A semaphore allows you to limit access to a specific number of simultaneous threads, so that you could have, for example, a maximum of two threads executing a specific code path at a time.
