c# - Mutex.ReleaseMutex() 即使同一个线程拥有它也会产生同步错误

Question

我创建了一个单独的依赖项来执行锁定和解锁，并且选择实现是 .NET 中的 Mutex 类。

interface ISynchronize 
{
  void Lock(lockId);
  void Release(lockId);
}

应用程序使用此依赖项来获取和释放锁，如下所示

Trace.WriteLine($"LOCK ({System.Threading.Thread.CurrentThread.ManagedThreadId}) Before locking Star ID {starId}");
this.Synchronizer.Lock(starId);
Trace.WriteLine($"LOCK ({System.Threading.Thread.CurrentThread.ManagedThreadId}) After locking Star ID {starId}");

SomeWorkToBeDone();

Trace.WriteLine($"LOCK ({System.Threading.Thread.CurrentThread.ManagedThreadId}) Before Releasing Star ID {starId}");
this.Synchronizer.Release(starId);
Trace.WriteLine($"LOCK ({System.Threading.Thread.CurrentThread.ManagedThreadId}) After Releasing Star ID {starId}");

系统间歇性地生成异常，并带有以下跟踪

LOCK (53) Before locking Star ID 1 
LOCK (53) After locking Star ID 1 
LOCK (53) Before Releasing Star ID 1 
Exception thrown: 'System.ApplicationException' in mscorlib.dll 
Object synchronization method was called from an unsynchronized block of code.

请注意线程 ID 是相同的，因此没有人可以说试图释放它的线程可能不拥有它。还有什么可能发生的？我不应该创建新对象并使用TryOpenExisting吗？

下面是依赖的实现

public void Lock(string lockId)
{
    var mutex = new Mutex(false, lockId);

    if (mutex.WaitOne(TimeSpan.FromSeconds(secondsToWait)) == false)
    {
        throw new SynchronizationTimedOutException($"Could not acquire lock within configured {secondsToWait} second(s)");
    }
}

public void Release(string lockId)
{
    var mutex = new Mutex(false, lockId);

    mutex.ReleaseMutex();
}
