In WPF, the Application class can be utilized to manage the global state and events of the application. Here are some common methods and properties of using the Application class:

  1. Get the instance of the current application.
Application currentApp = Application.Current;
  1. Get or set the main window of the application.
Window mainWindow = currentApp.MainWindow;
currentApp.MainWindow = new MainWindow();
  1. Start the application:
currentApp.Run();
  1. Exit the application.
currentApp.Shutdown();
  1. Monitor the startup and shutdown events of applications.
currentApp.Startup += (sender, e) =>
{
    // 在应用程序启动时执行的代码
};

currentApp.Exit += (sender, e) =>
{
    // 在应用程序退出时执行的代码
};
  1. Access or modify the resources of the application:
currentApp.Resources["MyResource"] = new MyResource();

These are some basic uses of the Application class, there are also more advanced uses such as handling exceptions, dealing with command-line arguments, and more. For further information, please refer to the official documentation from Microsoft.
