A WaitHandle can wait for multiple handles, a lock can wait for only one.

When you need it. Seriously, lock is syntactic sugar with <code>Monitor</code>, which probably uses WaitHandles internally.

Only use it if you need more flexibility (like e.g. holding on to a lock longer than the current scope...) or manage multiple locks in the right order etc.

blocks|key|2405512|text|当您有多个线程正在运行，并且您希望在继续执行其他操作之前等待其中一个或所有线程完成时，通常会使用WaitHandle。如果您想要阻止多个线程同时访问共享资源，则可以使用lock。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2405513|entityMap^0|1C|A|2C|4|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

<code>WaitHandle</code> is often used when you have multiple threads running and you want to wait for one or all of them to complete before you continue to do some other action. <code>lock</code> would be used if you want to prevent multiple threads from accessing a shared resource at the same time.

blocks|key|2096317|text|他们完成了完全不同的事情。lock用于将对特定代码块的访问限制为一次只能访问单个线程。WaitHandle是几个与并发相关的类(如Semaphore、Mutex、AutoResetEvent和ManualResetEvent+)的基类，这些类允许您以稍微不同的方式控制并发。例如，Semaphore允许您将并发限制为不超过N个线程，而不是单个线程。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|BOLD|entityRanges|data|2096318|entityMap^0|D|4|17|A|1T|9|23|5|29|E|2O|G|3W|9|4H|2|0^^$0|@$1|2|3|4|5|6|7|I|8|@$9|J|A|K|B|C]|$9|L|A|M|B|C]|$9|N|A|O|B|C]|$9|P|A|Q|B|C]|$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]|$9|X|A|Y|B|D]]|E|@]|F|$]]|$1|G|3|-4|5|6|7|Z|8|@]|E|@]|F|$]]]|H|$]]

They accomplish completely different things. A <code>lock</code> is used to limit access to a specific block of code to a single thread at a time. A <code>WaitHandle</code> is the base class for several concurrency-related classes, such as <code>Semaphore</code>, <code>Mutex</code>, <code>AutoResetEvent</code>, and <code>ManualResetEvent</code>, which allow you to control concurrency in slightly different ways. For instance, a <code>Semaphore</code> allows you to limit concurrency to no more than N threads, instead of a single thread.

blocks|key|4170343|text|锁从根本上不同于WaitHandle。用你写的锁，例如：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4170344|lock+(SomeResource)
{
++++//+do+stuff+here
}|code-block|syntax|javascript|4170345|第一行说，“我想独占访问该资源”，并将一直等到该资源可用(即没有其他人锁定它)。然后代码运行，最后锁被释放，以便其他人可以使用它。|4170346|WaitHandle用于等待某个事件发生。当你写的时候：|4170347|MyWaitHandle.WaitOne();|4170348|您的代码正在等待某个其他线程(可能在不同的进程中)发出该WaitHandle的信号。它发出的信号可能是任何东西。也许您正在等待另一个线程完成它的工作并说“我现在完成了”，然后您的代码才能继续。|4170349|因此，为了回答您的问题，当您希望获得对资源的独占访问时，您应该使用锁。当你想要得到一些事件的通知时，你应该使用WaitHandle。|4170350|entityMap^0|8|A|0|0|0|0|A|0|0|S|A|0|1J|A|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|10|8|@]|D|@]|E|$]]|$1|M|3|N|5|6|7|11|8|@$9|12|A|13|B|C]]|D|@]|E|$]]|$1|O|3|P|5|H|7|14|8|@]|D|@]|E|$I|J]]|$1|Q|3|R|5|6|7|15|8|@$9|16|A|17|B|C]]|D|@]|E|$]]|$1|S|3|T|5|6|7|18|8|@$9|19|A|1A|B|C]]|D|@]|E|$]]|$1|U|3|-4|5|6|7|1B|8|@]|D|@]|E|$]]]|V|$]]

A lock is fundamentally different from a <code>WaitHandle</code>. With a lock you write, for example:

<pre><code>lock (SomeResource)
{
 // do stuff here
}
</code></pre>

The first line says, "I want exclusive access to that resource," and will wait until that resource is available (i.e. nobody else has a lock on it). Then the code runs and at the end the lock is released so that others can use it.

<code>WaitHandle</code> is used to wait for some event to take place. When you write:

<pre><code>MyWaitHandle.WaitOne();
</code></pre>

Your code is waiting for some other thread (possibly in a different process) to signal that <code>WaitHandle</code>. What it signals could be anything. Perhaps you're waiting for another thread to finish its job and say, "I'm done now," before your code can continue.

So, to answer your question, you should use a lock when you want to gain exclusive access to a resource. You should use <code>WaitHandle</code> when you want to be notified of some event.
