TimerCallback - 可以改变时间吗？

Question

I have this function...

Instance(uint InstanceId) { }

Inside it is this code...

        mUpdater = new Timer(new TimerCallback(PerformUpdate), null, TimeSpan.FromMilliseconds(500), TimeSpan.FromMilliseconds(500));

It refreshes PerformUpdate every 500 milliseconds

In PerformUpdate i have a IF statement to calculate if a user has a specfic variable defined. How would I make it so if a user has the variable, then it only refreshes every 300 milliseconds instead of 500.

Oh and it cannot be set inside the Instance function as its a per user command and Instance is for every user.

Help would be much appreciated!

This looks like it's for the System.Threading.Timer , not System.Timers.Timer , correct? You can call the Change method on a System.Threading.Timer to change its start time and interval.

var variableDefined = true;        
var threadingCallback = new System.Threading.TimerCallback((o) => { });
var threadingTimer = new System.Threading.Timer(threadingCallback, null, 0, 500);
if (variableDefined) {
    threadingTimer.Change(0, 300);
}
