POWill passing a value type variable by reference into a static method thread safe?

Body
copied!<p>the code looks like this:</p> <pre><code>public class JobManager { public static void TrackExceptionCount(ref int exceptionCount) { Interlocked.Increment(ref exceptionCount); } //other helper methods } </code></pre> <p>I will call this method in other place like:</p> <pre><code>private static int _exceptionCount; JobManager.TrackExceptionCount(ref _exceptionCount); </code></pre> <p>I thought Interlocked.Increment will handle the thread-safe problem, right?</p> <p>Edit:</p> <p>I have multiple Job class like this:</p> <pre><code>class JobA { private static int _exceptionCount; public void method1() { Task.Factory.Start(()=>{ try { //Some code } catch(exception ex) { JobManager.TrackExceptionCount(ref _exceptionCount); } }); } public void method2() { Task.Factory.Start(()=>{ try { //Some code } catch(exception ex) { JobManager.TrackExceptionCount(ref _exceptionCount); } }); } } class JobB { private static int _exceptionCount; public void method1() { Task.Factory.Start(()=>{ try { //Some code } catch(exception ex) { JobManager.TrackExceptionCount(ref _exceptionCount); } }); } public void method2() { Task.Factory.Start(()=>{ try { //Some code } catch(exception ex) { JobManager.TrackExceptionCount(ref _exceptionCount); } }); } } </code></pre> <p>I believe that direct call Interlocked.Increment in the catch block probably a better way.</p> <p>But still want to know if the JobManager.TrackExceptionCount(ref _exceptionCount) will be working probably, or not</p> <p>Thanks.</p>
