Checking whether the current thread owns a lock

Question

Suppose I have the following code:

public class SomeClass()
{
    private readonly object _lock = new object();

    public void SomeMethodA()
    {
        lock         


        

Answer 1

Not the best thing to do but ...

bool OwnsLock(object someLockObj)
{
  if (Monitor.TryEnter(someLockObj))
  {
    Monitor.Exit();
    return false;
  }
  return true;
}

Debug.Assert(OwnsLock(_someLockObject), "_someLockObject should be locked when this method is called")
