Multiple parameter in Get Method

    [Route("api/LoginValues/itemcode/{username}/{password}")]
    [HttpGet]
    public IEnumerable<AC_Attendance> Get(string username, string password )
    {
        **var list = from g in db.AC_Attendances where g.username == username select g;**
        return list;
    }

How i want to make " g.username == username AND g.password== password "

For example I have taken employee(userID and password) as parameter.

public IEnumerable<Employee> Get(int Id, string password)
  {
     using (EmployeeDBEntities entities = new EmployeeDBEntities())
       {
           return entities.Employees.Where(tem => tem.ID == Id && tem.password 
                 == password).ToList();
       }
   }
