MVC2多模型定義從LINQ到SQL類VB.net

Question

我呼籲VB忍者在那裏。這是我的情況。我需要最終能夠將多個模型傳遞給視圖。目前我有一個LINQ到SQL類，當然，它有一堆生成的模型定義。我需要製作一個模型來實現多個模型。我有點理解如何在C＃中做到這一點，但這個項目正在測試我的VB技能。

這是從我的linq到sql模型的一些片段。我需要將這兩個結合到一個模型中傳遞給視圖。

文章型號：

<Global.System.Data.Linq.Mapping.TableAttribute(Name:="dbo.Articles")> _ 
Partial Public Class Article 
    Implements System.ComponentModel.INotifyPropertyChanging, System.ComponentModel.INotifyPropertyChanged 

    Private Shared emptyChangingEventArgs As PropertyChangingEventArgs = New PropertyChangingEventArgs(String.Empty) 

    Private _ArticleID As Integer 

    Private _ClassID As System.Nullable(Of Integer) 

    Private _Title As String 

    Private _ShortDescription As String 

    Private _LongDescription As String 

    Private _ByLine As String 

    Private _ArticleDate As System.Nullable(Of Date) 

    Private _SchoolClass As EntityRef(Of SchoolClass) 

員工型號：

<Global.System.Data.Linq.Mapping.TableAttribute(Name:="dbo.Staff")> _ 
Partial Public Class Staff 
    Implements System.ComponentModel.INotifyPropertyChanging, System.ComponentModel.INotifyPropertyChanged 

    Private Shared emptyChangingEventArgs As PropertyChangingEventArgs = New PropertyChangingEventArgs(String.Empty) 

    Private _StaffID As Integer 

    Private _ClassID As Integer 

    Private _PositionID As System.Nullable(Of Integer) 

    Private _StaffName As String 

    Private _Position As EntityRef(Of Position) 

    Private _SchoolClass As EntityRef(Of SchoolClass)

我可能會丟失的問題點，但第一個問題是，一切都在這些類是Private。也許你只是顯示支持領域？

假設的話，好像你只是想撰寫並通過演示模型暴露這些對象的一些數據：

Public Class StaffAndArticleViewModel 
    Private _Article As Article 
    Private _Staff As Staff 

    Public Sub New(ByVal a As Article, ByVal s As Staff) 
     _Article = a 
     _Staff = s 
    End Sub 

    ' now you just expose everything that the view requires 
    ' for example: 

    Public Property StaffName As String 
     Get 
      Return _Staff.Staff 
     End Get 
     Set(ByVal Value As String) 
      _Staff.Staff = Value 
     End Set 
    End Property
