Question

I have the following code segment in which I’m getting 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;
     }
}

on the if statement I’m getting error

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

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 your query, right in the where part.
