Timer

　　Latency Timer: A timer with a latency of X milliseconds.

Key code:

Private void button_click_1 (Object sender, routedeventargs e) {delaytimer () ;}/// <summary> /// delay timer /// </Summary> private void delaytimer () {// set the delay timer threadpooltimer tptimer = threadpooltimer. createtimer (async (timer) =>{ await dispatcher. runasync (coredispatcherpriority. high, () => {This. probar1.value + = 20;}) ;}, timespan. frommilliseconds (3000 ));}

　　Cyclic Timer: A timer that runs cyclically for n times with a latency of X milliseconds.

Key code:

Private void button_click_2 (Object sender, routedeventargs e) {periodictimer () ;}/// <summary >/// cyclic timer /// </Summary> private void periodictimer () {// loop timer threadpooltimer tptimer = threadpooltimer. createperiodictimer (async (timer) => {await dispatcher. runasync (coredispatcherpriority. high, () => {This. probar1.value = This. probar1.value + 1 ;}) ;}, timespan. frommilliseconds (100 ));}
