LINQ - 選擇新建 - 包括列表框中選定項

Question

使用ASP.NET 4.0

我有對LINQ惹上麻煩的.srvc_id是檢查的值和我下面的查詢只用於填充第一個複選框我的對象。

代碼

If Not IsNothing(lbServices.SelectedItem) Then 
      'NEW record INSERT values from list box to table. 
      myServices = (From item In lbServices.Items 
            Where item.Selected 
            Select New tbl_parent_to_child With 
              { 
                .id = myServices.child_id, 

                ----- .srvc_id is where I am stuck any help would be great. It is repeating the first selected check box. 

                .srvc_id = lbServices.SelectedValue, 
                .Active = True, 
                .CreateDate = DateTime.Now, 
                .CreateByID = SecurityMethods.GetLoginUserId(Session("AuthUser")), 
                .UpdateDate = DateTime.Now, 
                .UpdateByID = SecurityMethods.GetLoginUserId(Session("AuthUser")) 
              }).ToList() 
      For Each item In myServices 
       ctx.tbl_parent_to_child .Add(item) 
      Next 
     End If 

Try 
      ctx.SaveChanges() 
     Catch ex As Exception 
      Me.Master.HandleStatusMessageEvent((New StatusMessageEventArgs("Email a screen shot of this error to the Help Desk", StatusMessageType.ErrorMsg))) 
     End Try 

Answer 1

我相信你想使用的項目變量，.srvc_id = CInt(item.Value)

這類似於Listbox in asp.net not getting selected items
