  • By the way, a better way to show the structure of a table (better than a Select statement) is the Create Table statement you get if you right click a table in SQL Server Management Studio and choose "Script Table As -> Create To". That way you will show the types as well as the names. What database access mechanism are you using? It looks like either Linq2SQL or Entity Framework

  • the Entities from the database are mapped to a class in c#. Do you use Code First? for generating the entity framework layer?

You have to Specify the value before hitting into SaveChanges something like:



[HttpPost]
public User Register([FromBody]User user)
{
if (db.Users.Any(x => x.Email == user.Email))
throw new Exception("Username "" + user.Email + "" is already taken");
user.Email = "this is the Email from anywhere";
user.AID = "This is your Aid Value";
db.Users.Add(user);
db.SaveChanges();

//If you want to save Address
AddressEntity adr = new AddressEntity()
adr.address = "This is your new address";
db.Address.Add(adr);
db.SaveChanges();


return user;
}
