[c#] How does lock work exactly?

According to Microsoft's MSDN, the lock is equivalent to:

object __lockObj = x;
bool __lockWasTaken = false;
try
{
    System.Threading.Monitor.Enter(__lockObj, ref __lockWasTaken);
    // Your code...
}
finally
{
    if (__lockWasTaken) System.Threading.Monitor.Exit(__lockObj);
}

If you need to create locks in runtime, you can use open source DynaLock. You can create new locks in run-time and specify boundaries to the locks with context concept.

DynaLock is open-source and source code is available at GitHub
