我可以在代码中运行Azure函数吗？

Question

Can i run Azure Functions in code?

I mean, that having some c# project and host it on Azure i want to user Timer to do background work time by time. Have Azure SDK (or so on) some methods to implements timer line Azure Functions but in code?

PS i mean than can i use somelike Azure Function methods in App Service? For example, i want to run some piece of code every 5 minute, but not all code.

Hm.. thank you for your answers! What i mean:

 var azureTimer=new AzureFunctionTimer(5*60*1000);
 azureTimer.Elapsed+=SomeHandler;

Where AzureFunctionTimer is a part of Azure SDK (for example).

Why am i ask? I think (and may be i am wrong) that using a some timer like System.Threading.Timer utilize CPU timer at Azure host even event of elapsed time not rising yet.

For example:

  var timer=new Timer(5*60*1000);
      timer.Elapsed+=SomeHandler; 
      timer.Start(); //and while timer not rise event it utilize CPU already. (Am i right?)

And to prevent it should use some Azure SDK function like Azure Function (if it exist).

Answer 1

I'm not quite sure what you're asking, but if you're trying to use Azure Functions to run something every 5 minutes (or whatever period), you can make a timer function. This means that the function will automatically trigger every 5 minutes and run your code. When you use the Azure Dashboard to create a new function, one of the templates is for "Timer" which will let you run some code every period you define.

Answer 2

不可以，您不能使用计时器，Azure Functions将在5分钟后关闭，但是您可以在计时器上外部调用它们（webhooks），或使用内部Azure Functions cron计划或其他事件，例如队列中的新消息。

Azure Functions works in a reactive way, it will only run when an event happen. So the best you can do is use a kind of trigger (http Trigger for example) and call your Azure Function when you need.
