.net - 将 JSON 反序列化为对象 (VB.NET)

Question

我在从此 json 字符串获取一些值时遇到问题:

我尝试过使用和创建类，但除了前两个级别之外无法返回数据，例如我试图检索价格，但不知道如何提取此数据？

这是我正在使用的代码，它不返回任何内容:

<DataContract(Namespace:="")> _
    Public Class items

        <DataMember(Name:="product")>
        Public Property product As product

    End Class

    <DataContract(Name:="product", Namespace:="")> _
    Public Class product
        <DataMember(Name:="inventories")>
        Public Property inventories As inventories

    End Class

    <DataContract(Name:="inventories", Namespace:="")> _
    Public Class inventories
        <DataMember(Name:="price")>
        Public Property price As Double

    End Class

感谢您的帮助

使用 JSON.net 框架，我将我的类更改为以下内容，但仍然没有得到任何返回？

   Public Class items
        Public Property product As product()
        Public Property kind As String
    End Class

    Public Class product
        Public Property inventories As inventories()
    End Class

    Public Class inventories
        Public Property price As Double
    End Class

Answer 1

您看过 JSON.net 吗？

这是一个非常快的序列化/反序列化框架。一旦放入您的项目中，您可以执行以下操作:

Dim myObj as <Enter object type> _
= JsonConvert.DeserializeObject(Of <Enter object type>)("my json string here")

注意:我的示例可能略有偏差，没有检查它的语法:)
