C# Method for Adding Person Details to Database using Entity Framework

This C# code defines a method named AddPersonDetail that adds a person's details to a database using Entity Framework. Let me explain it in simpler terms:

The method takes a custom data object called PersonDetailModal as input, which contains information about a person, including their first name, last name, and email. The method's goal is to store this person's information in the database.

Here's how the code works step by step:

The method starts by creating a new instance of the database context called context. This context allows interaction with the database.

It then creates a new object of type PersonDetail, which represents a row in the "PersonDetail" table of the database.

The properties of the PersonDetail object (detail) are set based on the corresponding properties of the Person object provided as input. This means it copies the first name, last name, and email from the Person object to the detail object.

Next, the method checks if the Person object contains an Address property (representing the person's address). If an address is provided, it creates a new object of type AddressDetail, representing the person's address in the database.

If an address is available, the method sets the address-related properties of the AddressDetail object (Street, City, State, PostCode, Country) based on the corresponding properties from the Person.Address object.

If the person's address was provided, the AddressDetail object is assigned to the AddressDetail property of the PersonDetail object (detail).

The detail object, containing both the person's details and address if provided, is then added to the database using the PersonDetail DbSet's Add method.

After adding the person's details to the database, the changes are saved using context.SaveChanges().

Finally, the method returns the Id property of the detail object, which might be an auto-generated identifier representing the newly added record in the database.

In summary, this method takes a person's details, creates corresponding database entities, saves them to the database, and returns the identifier of the newly added person's record in the database.
