VB.net JSON反序列化

VB.net JSON反序列化

我建议你使用

JavascriptSerializer

过

DataContractJsonSerializer

。原因如下：

• JavascriptSerializer

  更快

  DataContractJsonSerializer

• DataContractJsonSerializer

  比

  JavascriptSerializer

  简单的序列化需要更多的代码。

您无需将

DataContract

and

DataMember

属性与

JavascriptSerializer

使用此数据类

<Serializable> _Public Class ApplicationItem    Public Property application_id() As String        Get Return m_application_id        End Get        Set m_application_id = Value        End Set    End Property    Private m_application_id As String    Public Property application_package() As String        Get Return m_application_package        End Get        Set m_application_package = Value        End Set    End Property    Private m_application_package As StringEnd Class

并使用它反序列化您的

jsonText

：

Dim jss As New JavascriptSerializer()Dim dict = jss.Deserialize(Of List(Of ApplicationItem))(jsonText)

如果仍要使用

DataContractJsonSerializer

，则可以使用以下代码反序列化：

Dim obj As New List(Of ApplicationItem)()Dim ms As New MemoryStream(Encoding.Unipre.GetBytes(json))Dim serializer As New System.Runtime.Serialization.Json.DataContractJsonSerializer(obj.[GetType]())obj = DirectCast(serializer.ReadObject(ms), List(Of ApplicationItem))ms.Close()ms.Dispose()
