Question

我正在创建一个应用程序，每当应用程序状态发生变化（即Paused，Stop，Start，InBackground）时，我想保存一些数据用于分析目的，并对我的服务器进行http调用。我做了r＆amp; d但没有任何相关的东西。任何解决方案都将不胜感激。

感谢。

Answer 1

在App.xaml.cs文件中查找描述您要跟踪的内容的事件处理程序。我会在这里发布它们以供参考。您可以根据这些事件的触发来跟踪应用程序的状态。我应该注意，其中一些事件确实有时间限制，因此在其中运行cpu密集型例程通常不是一个好主意。

// Code to execute when the application is launching (eg, from Start)
// This code will not execute when the application is reactivated
private void Application_Launching(object sender, LaunchingEventArgs e)
{
}

// Code to execute when the application is activated (brought to foreground)
// This code will not execute when the application is first launched
private void Application_Activated(object sender, ActivatedEventArgs e)
{
}

// Code to execute when the application is deactivated (sent to background)
// This code will not execute when the application is closing
private void Application_Deactivated(object sender, DeactivatedEventArgs e)
{
}

// Code to execute when the application is closing (eg, user hit Back)
// This code will not execute when the application is deactivated
private void Application_Closing(object sender, ClosingEventArgs e)
{
}

在App.xaml.cs中，有启动，激活，停用和关闭的事件。您可以在这些事件中编写代码以保存数据。
