后台代理Windows Phone 8仅运行一次？
[英]Background Agent Windows Phone 8 run only once?
问题描述
I do not have any experience with the background agent in windows phone, I am just curious if it is possible to start the background agent and let it run only once? 
我没有在Windows Phone中使用后台代理的经验，我只是好奇是否可以启动后台代理并使其仅运行一次？ cause according to the research I did it will run every few seconds. 根据我所做的研究，它会每隔几秒钟运行一次。
Is there perhaps a property I can set to let it run only once? 也许我可以设置一个属性使其仅运行一次？ at the moment the only way I am doing this is removing the agent at the point in code where it is not necessary anymore, but I don't think it is the correct way to do it? 目前，我这样做的唯一方法是在不再需要的代码点删除代理，但是我认为这不是正确的方法吗？

The background agent will run every 30 minutes. 后台代理将每30分钟运行一次。 I don't think it can disable itself (except if it crashes, but sounds like a bad practice), so there's probably no way to run it only once. 我不认为它可以禁用自身（除非它崩溃，但听起来像是一种不好的做法），因此可能没有办法只运行一次。 Still, if it you just make a quick check when it starts, decide that it shouldn't run, and immediately call the NotifyComplete method, the impact on the phone should be negligible. 尽管如此，如果您只是在启动时进行快速检查，决定不运行它并立即调用NotifyComplete方法，那么对电话的影响应该可以忽略不计。 Therefore, I wouldn't worry too much about it. 因此，我不会对此太担心。
