ASP, getting data from database

I'm using

var redirectEsetting = Esetting.FetchByRelatieId(dbConnection, (int)Context.Profile["RelatieID"]).First();

Now I need to check if redirectEsetting.RelatieID has a value, otherwise i'm going to use

    var redirectEsetting = Esetting.FetchByRelatieId(dbConnection, (int)Context.Profile["RelatieID"], true).First();

to get data from another place.

Yet, when I try

if(redirectEsetting.RelatieID == null) or something simular, it sais it's an int and it 'can't be null'.

Basically I need a way to check if I've got data in RelatieID
