エンティティフレームワークコードを使用して1対1の関係にする

Question

私はちょうど2つのテーブルの間に1つの関係を作りたいと思っていますテーブルがUSERであり、別のテーブルがUSERDETAILSであり、USERテーブルが主キーUSERIDとUSERDETAILSを持っていますテーブルにはキーID [autogenerated]とforeihgn key referanceユーザーテーブルを使用して...しかし、それは私がそれを作成しようとするといくつかのエラーになります。

モデル=> ユーザテーブル

public class User 
{ 
    [Key] 
    [Required(AllowEmptyStrings = false, ErrorMessage = "User Id Is Required!")] 
    [MaxLength(12, ErrorMessage = "You Have Exceed The Max length Of User ID which is [12] character!")] 
    [RegularExpression("[1-3]{2}-[0-9]{5}-[123]{1}|[1-3]{2}-[0-9]{7}-[123]{1}", ErrorMessage = "Invalid Id,It should [xx]-[xxxxx]-[x] or [xx]-[xxxxxxx]-[x]!")] 
    [Display(Name = "User ID")] 
    public string UserId { get; set; } 
    /// <summary> 
    /// //////// 
    /// </summary> 
    [Required(AllowEmptyStrings = false, ErrorMessage = "Password Is Required!")] 
    [MaxLength(20, ErrorMessage = "Password Max Length Is 20 Character!")] 
    [DataType(DataType.Password)] 
    [Display(Name = "Password")] 
    public string password { get; set; } 
    /// <summary>

    /// </summary> 
    [Required(AllowEmptyStrings = false, ErrorMessage = "User Level Is Required!")]

    [RegularExpression("^(?:admin|Admin|student|Student)$" , ErrorMessage="Invalid User Level!")] 
    [Display(Name = "User Level")] 
    public string level { get; set; } 

    //relationship with other table---- 

    public UserDetail UserDetail { get; set; } 
}

とエラー=>

と私は、ユーザーテーブル

を変更する=>してみてください

public List<UserDetail> UserDetail { get; set; } 

と

Answer 1

.....それは私のために動作しますが、それは、多くの関係に==>

1を作成します...しかし、私は1つが私please..orどんな提案をone.helpしたいです

1対1の場合、データベースはどのエンドがプリンシパルであり、どれが依存であるかを知る必要があります。その理由は、どちらか一方が最初に追加されなければならず、両者が互いに依存している場合には起こり得ないからです。あなたのUserクラスをプリンシパルにして、UserDetailsクラスを従属クラスにすることをお勧めします。しかし、流暢な設定を使わずにこれを定義する方法はわかりません。あなたの文脈で次に

public class User 
{ 
    ... 

    public class Config : EntityTypeConfiguration<User> 
    { 
     HasRequired(m => m.UserDetails).WithRequiredPrincipal(m => m.User) 
    } 
} 

：

protected override void OnModelCreating(DbModelBuilder modelBuilder) 
{ 
    modelBuilder.Configurations.Add(new User.Config()); 
}
