数组的反序列化不支持字典

Question

更新：

我有以下代码，我试图在其中使用returned JSON 数据，对其进行反序列化，并将该数据的一部分返回给用户。

<%@ Page Language="VB" Debug="True" EnableViewState="false" %>
<%@ Import Namespace="System.Web.Script.Serialization" %>

<script runat="server">
    Class Item
        Public Property some_number() As Double
            Get
                Return m_some_number
            End Get
            Set(ByVal value As Double)
                m_some_number = value
            End Set
        End Property
        Private m_some_number As Double
        Public Property some_text() As String
            Get
                Return m_some_text
            End Get
            Set(ByVal value As String)
                m_some_text = value
            End Set
        End Property
        Private m_some_text As String
        Public Property serial_number() As String
            Get
                Return m_serial_number
            End Get
            Set(ByVal value As String)
                m_serial_number = value
            End Set
        End Property
        Private m_serial_number As String
    End Class


    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        Response.Clear()
        Response.Write(set_profiles())
        Response.End()
    End Sub

    Function set_profiles() As String
        ' get returned json data
        Dim strChanged As String = CType(Request.Form("strChanged"), String)

        ' deserialize returned data
        Dim jss = New JavaScriptSerializer()

        ' assuming i need to change this line now?
        Dim dict As Dictionary = jss.Deserialize(List(Of Item))(strChanged)

        Return dict("some_number")
    End Function
</script>

我不明白如何反序列化到Item 类，然后如何取回数据。

您的数据是一个数组，您正试图将其反序列化为字典。这行不通。

要么更改输入数据，要么将其反序列化为数组。

您也可以声明一个类并在反序列化中使用它。

C#，抱歉：

class Item
{
    public double some_number { get; set; }
    public string some_text { get; set; }
    public string serial_number { get; set; }
}

并反序列化为List(Of Item)
