HOW TO：將實體加入至模型

發行項
02/28/2013

若要建立實體，將實體控制 Visual Studio 工具箱商務資料連線」 (BDC) 設計工具上。

若要在模型中新增實體

建立 BDC 專案或開啟現有的 BDC 專案。如需詳細資訊，請參閱建立商務資料連接模型。
在工具箱，從 BusinessDataCatalog 群組，請將實體在設計工具上的控制項。

新實體隨即出現在設計工具中。Visual Studio 會將 <Entity> 項目新增至專案內 BDC 模型檔案的 XML。如需 Entity 項目屬性的詳細資訊，請參閱 Entity (英文)。
在設計工具中，開啟 [實體的快顯功能表，選擇新增，然後選擇 [ 識別項。

新識別項隨即出現在實體上。

注意事項

您可以在 [屬性視窗] 中變更實體名稱和識別項。

注意事項
您可以在 [屬性視窗] 中變更實體名稱和識別項。

在類別中定義實體的欄位。您可以使用物件關聯式設計工具 (O/R 設計工具) 等其他工具將新類別加入至專案，也可以使用現有的類別。下列範例顯示名為 Contact 的實體類別。

Partial Public Class Contact

    Private _ContactID As Integer
    Public Property ContactID() As Integer
        Get
            Return _ContactID
        End Get
        Set(ByVal value As Integer)
            _ContactID = value
        End Set
    End Property
    Private _FirstName As String
    Public Property FirstName() As String
        Get
            Return _FirstName
        End Get
        Set(ByVal value As String)
            _FirstName = value
        End Set
    End Property
    Private _LastName As String
    Public Property LastName() As String
        Get
            Return _LastName
        End Get
        Set(ByVal value As String)
            _LastName = value

    End Property
    Private _EmailAddress As String
    Public Property EmailAddress() As String

            Return _EmailAddress
        End Get
        Set(ByVal value As String)
            _EmailAddress = value
        End Set
    End Property
    Private _Phone As String
    Public Property Phone() As String
        Get
            Return _Phone
        End Get
        Set(ByVal value As String)
            _Phone = value
        End Set
    End Property
    Private _EmailPromotion As Integer
    Public Property EmailPromotion() As Integer
        Get
            Return _EmailPromotion
        End Get
        Set(ByVal value As Integer)
            _EmailPromotion = value
        End Set
    End Property
    Private _NameStyle As Boolean
    Public Property NameStyle() As Boolean
        Get
            Return _NameStyle
        End Get
        Set(ByVal value As Boolean)
            _NameStyle = value
        End Set
    End Property
    Private _PasswordHash As String
    Public Property PasswordHash() As String
        Get
            Return _PasswordHash
        End Get
        Set(ByVal value As String)
            _PasswordHash = value
        End Set
    End Property
    Private _PasswordSalt As String
    Public Property PasswordSalt() As String
        Get
            Return _PasswordSalt
        End Get
        Set(ByVal value As String)
            _PasswordSalt = value
        End Set
    End Property

End Class

    public partial class Contact
    {
        public int ContactID { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string EmailAddress { get; set; }

        public int EmailPromotion { get; set; }
        public bool NameStyle { get; set; }
        public string PasswordHash { get; set; }
        public string PasswordSalt { get; set; }

    }
