终于{_someLock.EnterWriteLock（）;有道理吗？

I see in code of one big project such pattern:

我在一个大项目的代码中看到了这样的模式：

try {} finally { _someLock.EnterWriteLock(); }

try
{
...
}
finally
{
   _someLock.ExitWriteLock();
}

Does it make in any sense to enter lock in finally?

在任何意义上它最终都会进入锁定状态吗？

===================

Update: I found the source of such pattern.

更新：我找到了这种模式的来源。

No it doesn't. Empty try/finally block defends from excecuting finally even when the thread is aborted when it reaches try block.

不，不。即使线程在到达try块时被中止，空try / finally块也会终止执行。

In fact it is harmful in your case.

事实上，它对您的情况有害。

Consider if thread abort exception is thrown when executing try

考虑在执行try时是否抛出线程中止异常

try
{
    //Thread is here and abort requested
}
finally { _someLock.EnterWriteLock(); }//Aborted thread takes the lock!

try
{
...
}
finally
{
   _someLock.ExitWriteLock();//Never gonna execute since thread is aborted. You're screwed.
}

No, it does not. Maybe if you want to obfuscate your code

不，不是的。也许如果你想混淆你的代码
