備註

如果您的類別衍生自SPPersistedObject項目,不會實作此成員。

在大多數情況下,您可以實作Id屬性來建立名稱值的私用欄位,並為欄位周圍的包裝函式實作公用屬性。請考慮擁有建立值, get accessor 如果先前尚未設定屬性。請參閱範例。

Examples

下列程式碼範例會顯示實作,以確保它將會一律傳回有效GuidId屬性。

private Guid id;
public Guid Id
{
get 
    {
        if (id == Guid.Empty)
        {
            id = Guid.NewGuid;
        }
    return id;
    }
set {id = value;}
}
Private _id As Guid
Public Property Id() As Guid
Get
        If id = Guid.Empty Then
            id = Guid.NewGuid
        End If
    Return id
End Get
Set(ByVal value As Guid)
    id = value
End Set
End Property
