public void UploadEmployees(List<Employee> employees)
        
            SalesERPDAL salesDal = new SalesERPDAL();
            foreach (Employee emp in employees)
            
                salesDal.Employees.Add(emp);
                salesDal.Configuration.ValidateOnSaveEnabled = false;//增加这就就ok了
                salesDal.SaveChanges();
            
            
            
        

由于用的是MVC4 ,不支持这样写 

public void UploadEmployees(List<Employee> employees)
        
            SalesERPDAL salesDal = new SalesERPDAL();
            
                salesDal.Employees.AddRange(employees);
                
                salesDal.SaveChanges();
