你装箱拆箱后T已经不是之前的T了。。然后会导致在发送信号时已经不是LOCK时的线程了
Only the current owner of the lock can signal a waiting object using Pulse.
The thread that currently owns the lock on the specified object invokes this method to signal the next thread in line for the lock. Upon receiving the pulse, the waiting thread is moved to the ready queue. When the thread that invoked Pulse releases the lock, the next thread in the ready queue (which is not necessarily the thread that was pulsed) acquires the lock.
Monitor的code如下，非常简单： public static class Monitor { public static extern void Enter(Object obj); public static void Enter(Object obj, ref bool lockTaken) { if (lockTaken) ...
