copied!<p>If you're really trying to do an inter-process lock, as the name implies, you will want a way to detect if the Mutex has actually been acquired anyway, correct? I'm not sure how your code that uses your <code>InterProcessLock</code> would be ensured to be locked if there was no <code>IsAcquired</code> property. (Also, to protect against programmers who accidentally call Dispose twice, I'd set the <code>IsAcquired</code> to <code>false</code> in your <code>Dispose</code> method.)</p> <p>I've implemented the same thing myself (because I much prefer the using block to a try-finally just to release the mutex) and instead threw an exception when the timeout was exceeded, which, if I'm remembering the project correctly, did not call the Dispose method. </p> <p><b>Edit:</b> Added benefit of throwing the exception in the constructor: your critical section is also completely avoided, and you can perform error handling in the <code>catch</code> block, which could include the same method call your critical section had, anyway, though I personally would consider that a bad practice.</p> <p>Upon further reflection, rather than using <code>try ... catch</code> as specified in another answer, you could use the following on your dispose:</p> <pre><code>public void Dispose() { if (IsAcquired) { lock (mutex) { mutex.ReleaseMutex(); IsAcquired = false; } } } </code></pre> <p>It feels a little ironic to <code>lock</code> a mutex, but there you have it. While I totally agree that you shouldn't rely on Dispose being called because of the documentation with the IDisposable interface, I think it is incredibly convenient to have an inter-process critical section indicated by a <code>using() { }</code> block.</p>
