Where not in () statement with lambda

Question

Does anyone know how we can use where not in () instructions with lambda?

this is where id in() statement public List<abc> GetList(List<string> ID) { return db.abcs.Where(a => ID.Contains(a.id)).ToList<abc>(); } 

I would like to find how the cloud will be the opposite. "where id is not in ..."

Answer 1

Just add the not ( ! ) Operator:

 // Not In return db.abcs.Where(a => !ID.Contains(a.id)).ToList(); 

Answer 2

Why not?

 return db.abcs.Where(a => ! ID.Contains(a.id)).ToList<abc>();
