How to retrieve data of logged in user through Session

Question

I want to retrieve whole row of data from database when a specific user log in. and show it in my view of profile.
this is my Controller already assigned it a Session variable on ID, I now want to retrieve data from database through this U_ID.

public ActionResult Index(Account_Details log)
    {

        var obj = db.Account_Details.Where(u => u.Name.Equals(log.Name) && u.Password.Equals(log.Password)).FirstOrDefault();

        if (obj != null)
        {

            Session["loginid"] = obj.U_ID;
            Session["name"] = obj.Name;
            return RedirectToAction("Welcome");
        }

        else
        {
            return View();
        }
    }

this is my Model where I've assigned a foreign key to Basic_Detail table in database. So, that I can get Basic_Detail row of data through U_ID

 

public partial class Account_Details
{
    public Account_Details()
    {
        this.Basic_Details = new HashSet();
    }

    public int U_ID { get; set; }
    public string Name { get; set; }
    public string Password { get; set; }
    public string Email { get; set; }
    [DataType(DataType.Date)]
    [MinAge]
    public string DOB { get; set; }

    public virtual ICollection Basic_Details { get; set; }
}
