As you've observed, Windows Explorer will try to launch a new instance of your app when you double-click a file associated with your application. 如您所见，当您双击与应用程序关联的文件时，Windows资源管理器将尝试启动应用程序的新实例。 You can't change that. 您无法更改。 What you can do is have the new instance check whether an instance is already running and, if so, tell the running instance to load the file. 您可以做的是让新实例检查实例是否已在运行，如果已运行，则告诉正在运行的实例加载文件。 There are lots of ways to establish this sort of communication. 建立这种交流有很多方法。 You could listen on a port, periodically check for a file in a particular location, etc. How to do it is up to you. 您可以在端口上侦听，定期检查特定位置的文件，等等。如何操作取决于您。
