Question

How do you handle a null for a Max value in a linq to entities statement?

int UserLevelID = db.Characters.Where(o => o.UserId == UserID).Max(o => o.LevelID);

Answer 1

I’m not quite sure what you mean when you say count, since you aren’t referring to count anywhere in that code. If you are wonding how to handle a null o.LevelID you could do something like this:

Max(o => o.LevelID ?? -1);

?? is the coalesce operator in .NET

UPDATE

Try this:

db.Characters.Where(o => o.UserId == UserID).Max(o => o == null ? 0 : o.LevelID);
