Supervisar el progreso y el estado de la sincronización

Quizás quieras conocer el estado de las operaciones de sincronización en tu aplicación. Por ejemplo, podrías querer que un código específico se ejecute solo después de que todos los datos se sincronicen con App Services. También podrías querer proporcionar a los usuarios el estado de las operaciones de sincronización.

You can set up your Sync session to wait for changes to be uploaded or downloaded. You can also configure your Sync session to notify when the Sync connection status changes.

using Realms.Sync;
var realm = Realm.GetInstance(config);
await realm.SyncSession.WaitForDownloadAsync();

var session = realm.SyncSession;
var token = session.GetProgressObservable(ProgressDirection.Upload,
    ProgressMode.ReportIndefinitely)
        .Subscribe(progress =>
        {
            Console.WriteLine($@"Current upload progress:
                {progress.ProgressEstimate * 100}%");
        });
token.Dispose();

Obtener cambios en el estado de la conexión

To get the connection state of a SyncSession, set an event handler on the PropertyChanged event. The event handler is a standard .NET PropertyChangedEventHandler delegate that takes in a sender object and PropertyChangedEventArgs object. In the event handler, cast the sender to a Session object and check if the event argument's PropertyName property is Session.ConnectionState. You can then get the ConnectionState value, which will be one of the following:

• Conectando

• Conectado

• Desconectado

The following code demonstrates setting the event handler, casting the session object, and checking the Sync status:

public void SetupRealm()
{
    var appConfig = new AppConfiguration(myRealmAppId);
    app = App.Create(appConfig);
    user = app.LogInAsync(Credentials.Anonymous()).Result;
    config = new PartitionSyncConfiguration("myPartition", user);
    try
    {
        var realm = Realm.GetInstance(config);
        var session = realm.SyncSession;
        session.PropertyChanged += SyncSessionPropertyChanged!;
        realm.Dispose();
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
}
private void SyncSessionPropertyChanged(object sender, PropertyChangedEventArgs e)
{
    if (e.PropertyName == nameof(Session.ConnectionState))
    {
        var session = (Session)sender;
        var currentState = session.ConnectionState;
        if (currentState == ConnectionState.Connecting)
        {
            //session is connecting
        }
        if (currentState == ConnectionState.Connected)
        {
            //session is connected
        }
        if (currentState == ConnectionState.Disconnected)
        {
            //session has been disconnected
        }
    }
}
