Cannot pass an object of type "NHibernate.Hql.Ast.HqlBitwiseAnd" to enter "NHibernate.Hql.Ast.HqlBooleanExpression"

Question

I have the following code segment in which I get an error

using (var session = Database.OpenSession()) { var q = from x in session.Query<User>() where x.UserName == username & x.Password==EncodePassword(password) select x; if (q.Count() > 0) { result = true; } } 

in if statement, I get an error

 Unable to cast object of type 'NHibernate.Hql.Ast.HqlBitwiseAnd' to type 'NHibernate.Hql.Ast.HqlBooleanExpression'. 

Answer 1

What about:

 using (var session = Database.OpenSession()) { var q = from x in session.Query<User>() where x.UserName == username && x.Password==EncodePassword(password) select x; if (q.Count() > 0) { result = true; } } 

Check the double ampersand in the query right in the where part.
