asp.net-mvc - 返回对象名称为 MVC 的 Json 结果

Question

当 Controller 返回 json 结果时，对象名称似乎丢失，我通常不会介意，但 flexbox jquery 插件需要特定格式的 json 结果。

Flexcombobox 预期格式

{"results":[  
     {"id":"1","name":"Ant"},  
     {"id":"2","name":"Bear"},  
     {"id":"3","name":"Cat"},  
     {"id":"4","name":"Dog"},  
     {"id":"5","name":"Elephant"},  
     {"id":"6","name":"Fox"},  
     {"id":"7","name":"Guinea Pig"},  
     {"id":"8","name":"Horse"},  
     {"id":"9","name":"Iguana"},  
     {"id":"10","name":"Jaguar"}  
 ]} 

类(class)

Public Class FlexboxResult

    Private _id As String
    Public Property Id() As String
        Get
            Return _id
        End Get
        Set(ByVal value As String)
            _id = value
        End Set
    End Property

    Private _name As String
    Public Property Name() As String
        Get
            Return _name
        End Get
        Set(ByVal value As String)
            _name = value
        End Set
    End Property

End Class

Controller 代码

Function PartYearsList() As JsonResult
            Dim yearSelectList As List(Of FlexboxResult) = New List(Of FlexboxResult)

            For index As Integer = DateTime.Now.Year To 1955 Step -1
                yearSelectList.Add(New FlexboxResult() With {.Id = index, .Name = index})
            Next

            Return Me.Json(yearSelectList.ToArray(), JsonRequestBehavior.AllowGet)
End Function

Json 结果返回(缩短)

[{"Id":"2010","Name":"2010"},{"Id":"2009","Name":"2009"},{"Id":"2008","Name":"2008"}]

预期结果(缩短)

{"results": [{"Id":"2010","Name":"2010"},{"Id":"2009","Name":"2009"},{"Id":"2008","Name":"2008"}]}

Answer 1

在 C# 中，您可以使用匿名对象在退出时调整 JSON 结构:

// The ToArray() probably isn't necessary. Collections like List<T> are treated
//  as JavaScript arrays when JavaScriptSerializer turns them into JSON.
return Json(new { results = yearSelectList});

更新:

从 Dien，这是同一件事的 VB 语法:

Return Json(New With {Key .results = yearSelectList}, JsonRequestBehavior.AllowGet)
