我在ASP.NET中使用VB，并且一直在尝试从WebService（webmethod）序列化以下JSON。请帮助我使用的确切属性。

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
