推荐答案

编辑:使用新的 Xamarin Essentials Connectivity plugin，只需按照那里的说明操作:

Edit: this can be easily done with the new Xamarin Essentials Connectivity plugin, just follow the instructions there :D

在您的 App.cs(或 App.xaml.cs)中创建一个方法，如下所示:

Create a method in your App.cs (or App.xaml.cs) like this:

private async void CheckConnection()
{
    if(!CrossConnectivity.Current.IsConnected)
         await Navigation.PushAsync(new YourPageWhenThereIsNoConnection());
    else
         return;
}
    

并在您的主应用程序方法中使用它，如下所示:

And use it on your main app method like this:

public App()
{
    InitializeComponent();

    var seconds = TimeSpan.FromSeconds(1);
    Xamarin.Forms.Device.StartTimer(seconds,
        () =>
        {
             CheckConnection();
        });
}
