有没有办法在设备上调试飞行模式？我试着开启飞行模式，在设备设置和禁用我的电脑上的互联网连接，但NetworkInterface.GetIsNetworkAvailable（）仍返回true。难道我做错了什么？

Is there a way to debug airplane mode on the device? I tried turning airplane mode on in the device settings and disabling the internet connection on my computer, but NetworkInterface.GetIsNetworkAvailable() still returns true. Am I doing something wrong?

I just tested this on an actual device and indeed, it returns a constant true.
