How to save data in User class?

Question

I want to read data from db and save data in class of user. But this class has only UserId and UserName. I want to save another information.what should I do. This is my code:

User user = new User();
user.UserId = (int)ddr["id"];
user.UserName = (string)ddr["name"];

Where is `User` defined? Is this a built-in class or something you control? — David, May 10 '16 at 17:20
I want to save (for example) phone, but there isn't a field for that. — Maryam, May 10 '16 at 17:24
You need to do some reading on the ASP.NET Identity framework. — Spivonious, May 10 '16 at 17:30
Simply add an extra field to your to your class `User` where you've defined it. — Raktim Biswas, May 10 '16 at 17:35
the phone is a field in database . I want to read it , then add it to class User. — Maryam, May 10 '16 at 17:46
If you own the `User` class just add the members you need. If not, then maybe the best solution is inheritance through composition. That is: create a new class (something like `UserInfo`) and add a property of type `User` in the new class. — shadow, May 10 '16 at 17:47
@Maryam `I don't define the class User . it is a built-in class.` then create your own class?? — Arian Motamedi, May 10 '16 at 17:48
you can even override a built-in class. this might help http://stackoverflow.com/questions/4910108/how-to-extend-c-sharp-built-in-types-like-string or, just create your own class and add the fields you wish to give. — Raktim Biswas, May 10 '16 at 17:53
ok. now how can I use the object of class (that I made it myself) in other pages of my site? — Maryam, May 10 '16 at 17:56

Inheritance through composition example:

public class UserInfo
    {
        private User User { get; set; }

        public int UserId
        {
            get { return User.UserId; }
            set { User.UserId = value; }
        }

        public string UserName
        {
            get { return User.UserName; }
            set { User.UserName = value; }
        }

        public string Email { get; set; }



        public UserInfo()
        {
            User = new User();
        }
    }

So you can use the new UserInfo as User.

UserInfo user = new UserInfo();
user.UserId = (int)ddr["id"];
user.UserName = (string)ddr["name"];
user.Email = (string)ddr["email"];

As you would use a `User` object. – shadow May 10 '16 at 18:25
:) . It's unknown in other pages. I can't write textbox1.text=user.Email. – Maryam May 10 '16 at 18:27
@Maryam create an object on that page too `UserInfo user = new UserInfo();` and then you'll have the access `textbox1.text=user.Email` – Raktim Biswas May 10 '16 at 18:32
I'm afraid that I can't help you from here. It's all about the design of your application. For sure there must be some changes so the new class can be used. – shadow May 10 '16 at 18:34
the UserInfo class is unknown in other pages. and if I write your code the Email hasn't the value that I given in previous page. It has a new value. Doesn't it?! – Maryam May 10 '16 at 18:38
It is a bit confusing for me because I don't know if we are talking about MVC, Web Forms, a Layered application..... if you have controllers, repositories, .... For start I would change in the UI (in just one page) the `User` with `UserInfo` and take it from there. I'm very sorry but I can't help you more behind a keyboard. – shadow May 10 '16 at 18:46
