有没有更好的解决方案，然后ViewData

我有一个模型RETLogModel上运行的视图，它从一个完全不同的连接字符串，然后是一个名为RecordsTaskViews表。我需要根据我的模型收集的信息从RecordsTaskViews传递信息。目前我的函数如下：有没有更好的解决方案，然后ViewData

Function RETLog(model As RETModels.RETLogModel) As ActionResult 
    Dim id As Integer = model.ActivityIDReturn 
    Dim id2 As Integer 
    Dim PS As RecordsTaskView = GlobalVar.db.PS.RecordsTaskViews.Find(id) 
    If model.ActivityIDReturn > 0 Then 
     id2 = model.ActivityIDReturn 
    Else : id2 = PS.RefActionID 
    End If 
    If model.ActivityIDError > 0 Then 
     ViewData("ActivityIDErrorValue") = model.ActivityIDError 
    Else : ViewData("ActivityIDErrorValue") = PS.RefActionID 
    End If 
    Dim PS2 As RecordsTaskView = GlobalVar.db.PS.RecordsTaskViews.Find(id2) 
    If model.ActivityIDReturn > 0 Then 
     If PS IsNot Nothing Then 
      ViewData("QRefActionID") = PS.RefActionID 
      ViewData("QQutDesc") = PS.QutDesc 
      ViewData("QTaskDesc") = PS.TaskDesc 
      ViewData("QClientCode") = PS.CltCode 
      ViewData("QClientName") = PS.CltDesc 
      ViewData("QMemberID") = PS.BenIDin 
      ViewData("QMemberName") = PS.BenNameLast & ", " & PS BenNameFirst 
      ViewData("QDateStart") = CDate(PS.DateStart).ToString("MM/dd/yyyy") 
      ViewData("QDateRes") = CDate(PS.DateResolution).ToString("MM/dd/yyyy") 
      ViewData("QCreateUser") = PS.UserIDCreation 
      ViewData("QLastChangeUser") = PS.UserIDLastChanged 
      ViewData("QDateReport") = CDate(PS.DateReport).ToString("MM/dd/yyyy") 
     Else 
      ViewData("QQutDesc") = "" 
      ViewData("QTaskDesc") = "" 
      ViewData("QClientCode") = "" 
      ViewData("QClientName") = "" 
      ViewData("QMemberID") = "" 
      ViewData("QMemberName") = "" 
      ViewData("QDateStart") = "" 
      ViewData("QDateRes") = "" 
      ViewData("QCreateUser") = "" 
      ViewData("QLastChangeUser") = "" 
      ViewData("QDateReport") = "" 
     End If 
     If PS2 IsNot Nothing Then 
      ViewData("ORefActionID") = PS2.RefActionID 
      ViewData("OQutDesc") = PS2.QutDesc 
      ViewData("OTaskDesc") = PS2.TaskDesc 
      ViewData("OClientCode") = PS2.CltCode 
      ViewData("OClientName") = PS2.CltDesc 
      ViewData("OMemberID") = PS2.BenIDin 
      ViewData("OMemberName") = PS2.BenNameLast & ", " & PS.BenNameFirst 
      ViewData("ODateStart") = CDate(PS2.DateStart).ToString("MM/dd/yyyy") 
      ViewData("ODateRes") = CDate(PS2.DateResolution).ToString("MM/dd/yyyy") 
      ViewData("OCreateUser") = PS2.UserIDCreation 
      ViewData("OLastChangeUser") = PS2.UserIDLastChanged 
      ViewData("ODateReport") = CDate(PS2.DateReport).ToString("MM/dd/yyyy") 
     Else 
      ViewData("ORefActionID") = "" 
      ViewData("OQutDesc") = "" 
      ViewData("OTaskDesc") = "" 
      ViewData("OClientCode") = "" 
      ViewData("OClientName") = "" 
      ViewData("OMemberID") = "" 
      ViewData("OMemberName") = "" 
      ViewData("ODateStart") = "" 
      ViewData("ODateRes") = "" 
      ViewData("OCreateUser") = "" 
      ViewData("OLastChangeUser") = "" 
      ViewData("ODateReport") = "" 
     End If 
    End If 
    If ModelState.IsValid Then 
    End If 
    Return View(model) 
End Function

我的问题是，这是明显ViewData元素的船负荷。正如我已经有在视图中指定的@ModelType RETModels.RETLogModel本身，是否有更高效的方式将数据传递给视图？

是的，使用包含所有相关（组合）字段并将其绑定到视图的ViewModel。

然后使用自动对象映射器（如AutoMapper）将数据从业务模型复制到ViewModel。
