字典不支持反序列化数组

更新：

我有以下代码，我尝试使用returned JSON数据，反序列化它，并将该数据的一部分返回给用户。

    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  

我不明白如何反序列化到Item类，然后如何恢复数据。

您的数据是一个数组，您正在尝试将其反序列化为Dictionary。 这不行。

更改输入数据或将其反序列化为数组。

您还可以声明一个类并在反序列化中使用它。

C＃，对不起：

 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)
