You need to use the Close and Dispose methods to destroy resources. Note: Once the server timer object does not have any reference, the garbage collector recycles the object. Therefore, you need to use GC before the reference is invalid. the KeepAlive method does not recycle the instance. We recommend that you declare the server timer at the class level or higher to prevent this problem;Server timers can on
