I have this line of code that i want to return true/false if no "Sensor" exists.
I know for sure that i have 1 sensor with no data, and then i want to add data to it if it doesn't have data already.
var dataExsist = Context.SensorLogs
.FirstOrDefault(a => a.SensorId == sensor.SensorId);
It will find all the sensors that have data, but not the one without data.
I tried with .Count
to see if it would show 0, but it doesn't.
Any help is greatly appreciated.
