MVC 3沒有綁定的模型屬性

Question

是否可以在未綁定到數據庫的模型中包含屬性？例如：

Public Class Tbl_Forum_Topic 

    <Key()> Public Property FTopic_ID() As Integer 
    <ForeignKey("Tbl_Forum")> _ 
    Public Property FTopic_Forum_ID() As Integer 
    Public Property FTopic_Employee_ID() As Integer 
    Public Property FTopic_Resource_ID() As Integer 
    Public Property FTopic_Title() As String 
    Public Property FTopic_Content() As String 
    Public Property FTopic_Create_Date() As Nullable(Of Date) 
    Public Property FTopic__Deleted() As Nullable(Of Boolean) 
    Public Property FTopic_Deleted_Date() As Nullable(Of Date) 
    Public Property FTopic_Status() As Nullable(Of Boolean) 
    Public Property FTopic_Publish() As Nullable(Of Boolean) 

    Public Overridable Property Tbl_Forum() As Tbl_Forum 

    Public Overridable Property Tbl_Forum_Replies() As ICollection(Of Tbl_Forum_Reply) 

    Public Overridable Property Last_Reply_User_Name() As String 

End Class 

最後一項叫做Last_Reply_User_Name()。它不在我的數據庫中，但我想循環並在我的控制器操作中執行計算，以根據來自其他數據庫表的值進行設置。當我嘗試此代碼時，出現錯誤Invalid column name 'Last_Reply_User_Name'.。

謝謝。

您需要將<NotMapped>屬性應用於屬性。
