推荐答案

而没有看到代码并不是预期的那样.如果使用锁，则在释放锁之前，禁止同时进行的操作获取相同的锁.因此，您正在排队寻求锁定.

Without seeing the code isn''t that what''s expected to happen. If you use lock, you prevent simultaneous operations from acquiring the same lock until the lock is released. So you''re queueing for the lock.

尽管使用C#4 [假定标记！]，但我认为您不必担心锁定对象/线程池.您可以使用 Parallel.For [

While using C#4 [Assumed from the tag!] , I don''t think that you have to worry about locking the objects / Threadpool. You can make use of Parallel.For[^] method.
