#1 - Why are you trying to do this? This doesn't look like it performs anything useful.
#2 - It appears that Microsoft's implementation is more accepting than the specifications for Monitor.Exit. The docs are pretty clear. -- arlie -----Original Message----- From: Moderated discussion of advanced .NET topics. [mailto:[EMAIL PROTECTED] On Behalf Of Jeff Varszegi Sent: Friday, October 17, 2003 10:59 AM To: [EMAIL PROTECTED] Subject: [ADVANCED-DOTNET] Synchronization question I've written some code that runs fine on Windows, but when someone tried to run it under Mono, it threw this exception: Unhandled Exception: System.Threading.SynchronizationLockException: Not locked by this thread The code in question is pretty detailed, but the synchronization scheme boils down to this: I have two overlapping (avoiding the word "interlocked") synchronized regions, where I start, the first, start the second, exit the first, then exit the second, like this: object monitor1 = new object(); object monitor2 = new object(); lock (monitor1) { // ... lock (monitor2) { Monitor.Exit(monitor1); // ... } } I was thinking that this might be because the Mono implementation requires that if you use the Monitor class to release a lock, you must have used it to acquire the same lock (since it must be just holding a handle to the current thread set when you called the Enter() method), and Microsoft's .NET wasn't built that way. This brings up the question of whether this behavior is part of the platform specification. Any quick answers for this .NET newbie?
