copied!<p>Use <a href="http://msdn.microsoft.com/en-us/library/system.threading.timer.aspx" rel="noreferrer"><code>System.Threading.Timer</code></a>. You can specify a method to call periodically.</p> <p>Example:</p> <pre><code>Timer timer = new Timer(Callback, null, TimeSpan.Zero, TimeSpan.FromMinutes(5)); public void Callback(object state) { Console.WriteLine("The current time is {0}", DateTime.Now); } </code></pre> <p>You can use the second parameter to pass state to the callback.</p> <p>Note that you'll need to keep your application alive somehow (e.g., run it as a service).</p> <p>As for how to make sure that it runs at <code>hh:mm</code> where <code>mm % 5 == 0</code>, you can do the following.</p> <pre><code>DateTime now = DateTime.Now; int additionalMinutes = 5 - now.Minute % 5; if(additionalMinutes == 0) { additionalMinutes = 5; } var nearestOnFiveMinutes = new DateTime( now.Year, now.Month, now.Day, now.Hour, now.Minute, 0 ).AddMinutes(additionalMinutes); TimeSpan timeToStart = nearestOnFiveMinutes.Subtract(now); TimeSpan tolerance = TimeSpan.FromSeconds(1); if (timeToStart < tolerance) { timeToStart = TimeSpan.Zero; } var Timer = new Timer(callback, null, timeToStart, TimeSpan.FromMinutes(5)); </code></pre> <p>Note that the <code>tolerance</code> is necessary in case this code is executing when <code>now</code> is very close to the nearest <code>hh:mm</code> with <code>mm % 5 == 0</code>. You can probably get away with a value smaller than one second but I'll leave that to you.</p>
