Question

I am using c# MVC I am trying to create 2 new records in 2 tables – employee and address table.
I have the following so far:

    db.employee.AddObject(empmodel.employee);
    db.address.AddObject(empmodel.address); 
    db.SaveChanges();

When an employee record is created, it creates an EmpID record which is autogenerated. I need to get that EmpID and create a new record in the address table with that EmpID as as there is a primary foreign key relationship between the 2 tables.

I am not sure how to get the EmpID from employee table and then create a new record for the address table. I thought I could get it after AddObject but it did not create an employee record.

I know you’re not supposed to just give feedback, but in this case, this answer is right on, no need to go further. If you create a model, using a database table, as long as that database table has an ID field. It will create the get/set methods for you. In mine, it even created a more elaborate get/set method probably because the name of my ID field is ProdID. But you can expand the model.cs file, (after you create the model from the database) and see the get/set method these guys are talking about. In the case you are using a GUID you can just use

card.Guid = Guid.NewGuid();

The NewGuid() method in the controller create function.
