我有两个相关的简单视图模型。我可以通过linq include语句查询数据,但是当我将它注入viewmodel时,icollection什么都没有?
的ViewModels:
Public Class EventViewModel
Public Property EVENTID As Integer
Public Property TITLE As String
Public Overridable Property USERS() As ICollection(Of UserViewmodel)
End Class
Public Class UserViewModel
Public Property USERID As Integer
Public Property EVENTID As Integer
Public Property NAME As String
End Class
查询:
Dim dataObject As EVENTTABLE = db.EVENTTABLE.Include("USERTABLE").Single(Function(c) c.EVENTID= "1")
用户在对象中!
注射:
viewModel.InjectFrom(dataObject)
用户什么都没有?
答案 0 :(得分:0)
好的,在这个问题的帮助下找到了它:How to map lists with ValueInjector
我需要将USERTABLE查询到一个列表中并像下面所述注入它:
查询:
Dim dataSubObject = (From ....).toList()
注射:
Dim viewModel = New EventViewModel
viewModel.USERS= dataSubObject.Select(Function(x) New ImageViewModel().InjectFrom(x)).Cast(Of ImageViewModel)().ToList()
