Question

SELECT TOP 1000 
    [ID]
    ,[Name]
    ,[Phone]
    ,[Email]
    ,[AID]
    ,[Password]
    ,[Date/time]
    ,[IsVerify]
    ,[ProfilePicture]
FROM 
    [ChefODine].[dbo].[User]

这是我的用户表AID是地址表的外键，具有以下字段。

SELECT TOP 1000 
    [ID]
    ,[Location]
    ,[LAT]
    ,[Lng]
FROM 
    [ChefODine].[dbo].[Address]

我想通过Web服务在数据库中添加用户地址和其他信息。我希望每当用户添加他的信息时，该地址将保存在地址表中，而AID将保存在用户表中。这是我的代码，请指导我，我是新手。

[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");

    db.Users.Add(user);
    db.SaveChanges();

    return user;
}

Answer 1

输入SaveChanges之类的值之前，您必须先指定值：

[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;
}
