Inserting data based on my selected fields only

Question

Dear Experts,

 

I am a newbie for ASP.NET and I have a question to seek for your advice.

 

I am creating a new record in the database & below is the code I am using now in the controller: 

public ActionResult Create(TCustomer customer)
        {
            if (ModelState.IsValid)
            {
                _CustomerRepository.NewCustomer(customer);
                _CustomerRepository.Save();
                return RedirectToAction("Index");
            }
            return View();
        }

 

 here is the code in my Repo :

public void NewCustomer(TCustomer customer)
       {
           _dbContext.TCustomers.Add(customer);
           Save();
       }

 My question is, how can i save the database on the selected fields only?

 

For example, I have Customer_name, Customer_phone, customer_dob & customer_age

 

 and I just want to select Customer_name, Customer_phone to be inserted into the database. and before I save the customer_name, customer_phone I may need to find turn the data.

 

Hope you understand what i am saying and advise me.

 

Many thanks
