Unity null check

Questions & Answers

Ok, I’m executing this code:

_gameData.Initialize();
var mission = _gameData.Missions.ElementAt(0);
Debug.Log("Mission is: " + mission.Details.MissionText);
if (mission == null)
{
    Debug.Log("Mission is null");
    return;
}
Debug.Log("Mission is: " + mission.Details.MissionText);

And I get this output:

How in the world is that possible? Where’s the logic?
How am I supposed to make null checks now? And how will null propagation from C#6 work with this?

I think it’s probably because it goes there twice (since missions count is 2) and the second one automatically skips the Debug.Log cause it can’t access Details.MissionText from a nullobject (though it should make an error i suppose, but i know sometimes it doesn’t, and just randomly decides to skip code).
Have you tried debugging it with breakpoints to see what exactly is happening?
