誰能幫助我與使用DataContext.CreateDatabase（）函數創建時沒有被生成的表軌道和表TrackArtist之間的外鍵的原因我的數據庫基於我的實體？我的表/列生成良好，但我的關係不是作爲FK約束生成的。Sql的Linq - FK不會產生創建數據庫時
我正在嘗試在表格之間創建FK，以便TrackArtist表格可以作爲Track表格的'lookup'表格。
[Table(Name="Track")]
public class Track
{
[Column (IsPrimaryKey=true, IsDbGenerated=true, AutoSync=AutoSync.OnInsert)]
public int Id { get; set; }
[Column]
private int TrackArtistId {get; set;}
private EntityRef<TrackArtist> _trackArtist;
[Association(Name="FK_Track_TrackArtist", ThisKey = "TrackArtistId", OtherKey="Id", Storage = "_trackArtist")]
public TrackArtist TrackArtist
{
get { return this._trackArtist.Entity; }
set { this._trackArtist.Entity = value;
TrackArtistId = value.Id;
}
}
[Column (CanBeNull=false)]
public string Description { get; set; }
}
[Table(Name="TrackArtist")]
public class TrackArtist
{
[Column(IsPrimaryKey=true, IsDbGenerated=true, AutoSync=AutoSync.OnInsert)]
internal int Id { get; set; }
[Column (CanBeNull=false)]
public string Name { get; set; }
}
