Mercury Event Types

// Example: Receiving an access event via EventStream
await foreach (var ev in client.EventStreamAsync(instance, 
    MercuryEvents.AccessGranted | MercuryEvents.AccessDenied))
{
    var eventData = ev.EventData;
    
    // Access common properties
    string controller = eventData["Controller"].AsString;
    DateTime messageTime = eventData["MessageTimeUTC"].ToUniversalTime();
    
    // Access-specific properties
    string reader = eventData["Reader"].AsString;
    string person = eventData["Person"].AsString;
    long cardNumber = eventData["EncodedCardNumber"].AsInt64;
    
    Console.WriteLine($"{person} accessed {reader} at {messageTime}");
