Check internet Connection

Question

Good Day All

i want to check if the user is connected to the internet , i switch off my wifi internet as depicted below for testing purpose

and after that i tried to access a function that needs database connection , before i make a call , i call this function

public static bool CheckInternetConnection()  
{  
    var current = Connectivity.NetworkAccess;  
  
    if (current == NetworkAccess.Internet)  
    {  
        return true;  
    }  
    else  
    {  
        return false;  
    }  
}  

for some reason i am getting "True" instead of False to there is no internet on the device.

Thanks

Hello,

If you only switch off the internet on your Windows machine, the Android Emulator can't test the state. Please try to debug on your real device. Or open the airplane mode in Setting under NetWork&Internet of your Android Emulator.

But VS can't debug in airplane mode on my side, because it is unable to connect debugger-agent. I'm not sure if this issue exists on your side.
My testing on Android Emulator:

public App()  
        {  
            InitializeComponent();  
            var current = Connectivity.NetworkAccess;  
            if (current == NetworkAccess.Internet)  
            {  
                MainPage = new MainPage();  
            }  
            else  
            {  
                MainPage = new NoInternetPage();  
            }        
        }  

When I turn on airplane mode and reopen the app, it will go to NoInternetPage.
