Populate a mvc5 list?

问题

Right now I can create games under the Games/Create. And I can make a post under Post/Create.

But my problem is that right now my public int GameId { get; set; } gets populated with the items that is in my Game table in my SQL database. Which is just fine that's how I like it.

But I want public string Title { get; set; } to the populated the same way with the values that are in the Game database.

public int GameId { get; set; } gets populated with a dropdownlist with the values that is in my Game table.

And as for public string Title { get; set; } I have to enter it manually. I want that to be populated the same way as GameId

This is my Post Model

public class Post
{
    [Key]
    public int PostId { get; set; }

    //URL
    [Display(Name = "URL")]
    [StringLength(80)]
    public string Url { get; set; }
    //User
    [Display(Name = "User")]
    public virtual ApplicationUser User { get; set; }

    //Game
    [Display(Name = "Game")]
    public int GameId { get; set; }
    [Display(Name = "Next Game")]
    public string Title { get; set; }
    public virtual Game Game { get; set; }

    //Time
    private DateTime? _date;
    public DateTime? Date
    {
        get
        {
            if (_date == null || _date.ToString() == "1/1/0001 12:00:00 AM")
            {
                return _date = DateTime.Now;
            }
            return _date;
        }
        set
        {
            _date = value;
        }
    }

And this is my Game Model

    public class Game
{
    [Key]
    public int GameId { get; set; }

    //Game
    [Display(Name = "Game")]
    public string Title { get; set; }

    //User
    [Display(Name = "User")]
    public virtual ApplicationUser User { get; set; }
}

Actually you don't need your property Title in your Post Model, in your controller you can do something like this to get all data of Game.

using (var db = new YourDbContext())
{
    var post = db.Posts().Include(g => g.Game).FirstOrDefault();
    var gameTitle = post.Game.Title;
}
