我在 ASP.NET 中使用 VB，我一直在考虑尝试从 WebService（webmethod）序列化下面的 JSON。请帮助我使用的确切属性。

{
    "api_version" : 4 ,
    "hotel_ids" : [97497],

像这样使用代码：这是我的实体类

Public Class Book

   ' autocomplete example needs "id", "value" and the "label" variables to be sent back.
   ' do not change or remove "id", "value" and the "label" variables
   Public Property id() As String
   Public Property label() As String
   Public Property value() As String

   Public Property Author() As String
   Public Property Genre() As String
   Public Property Price() As String
   Public Property Publish_date() As String
   Public Property Description() As String
End Class


Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

    '  Query string 'term' is for autocomplete. By default, it sends the variable 
    '  "term" with the search word to the backend page.
    Dim searchText As String = context.Request.QueryString("term")
    Dim books As Collection = New Collection

    Dim ds As New DataSet()
    ds.ReadXml(HttpContext.Current.Server.MapPath("jsonfile"))
    Dim dv As DataView = ds.Tables(0).DefaultView
    dv.RowFilter = [String].Format("title like '{0}*'", searchText.Replace("'", "''"))

    Dim book As Book
    For Each myDataRow As DataRowView In dv
        book = New Book()
        book.id = myDataRow("id").ToString()
        book.value = myDataRow("title").ToString()
        book.label = myDataRow("title").ToString()
        book.Author = myDataRow("author").ToString()
        book.Genre = myDataRow("genre").ToString()
        book.Price = myDataRow("price").ToString()
        book.Publish_date = myDataRow("publish_date").ToString()
        book.Description = myDataRow("description").ToString()
        books.Add(book)
    Next

    Dim serializer As JavaScriptSerializer = New JavaScriptSerializer
    Dim jsonString As String = serializer.Serialize(books)
    context.Response.Write(jsonString)

End Sub
