[UWP] [C＃] DispatcherTemer [英] [UWP][C#] DispatcherTImer

问题描述

如何使用DispatcherTimer？ 

我想在UWP中创建一个计时器，这使我能够每秒更新一次。

例如：

我已经使用我的rfduino设置了mpu6050。因此，当我点击"阅读"时，它将显示"90度"。但如果我将我的mpu6050移动到另一个角度，我的c＃将自动更新新值。

可以有人帮我这个吗？  

解决方案

对于一次性计时器，请考虑
CreateTimer ：

• https://docs.microsoft.com/en-us/windows/uwp/threading-async/use-a-timer-to-submit-a-work-item

如果需要，您可以在处理程序的末尾安排新的工作项。

TimeTrigger ：

How do I use DispatcherTimer ? 

I want to create a timer in UWP which enables me to update values every second.

For example:

I have setup a mpu6050 with my rfduino. So when I click "read", it will display "90 degree". But if I were to move my mpu6050 to a different angle, my c# will update the new value automatically.

Can anyone help me with this ?  

解决方案

For one-shot timer, consider CreateTimer:

• https://docs.microsoft.com/en-us/windows/uwp/threading-async/use-a-timer-to-submit-a-work-item

At the end of the handler you can schedule a new work item, if required.

For periodic events, check TimeTrigger:

• https://docs.microsoft.com/en-us/windows/uwp/launch-resume/run-a-background-task-on-a-timer-
