Convert vb.net class object to JSON string in vb.net -

i c# developer , have requirement work in vb.net project. facing simple issue need convert class object json string in vb.net.problem when check string after conversion getting output as:

[{},{},{}] 

i trying store value of 3 objects getting 3 empty objects {}. code this:

imports system.web.script.serialization  partial class test     inherits system.web.ui.page      protected sub page_load(byval sender object, byval e system.eventargs) handles me.load          dim serializer new javascriptserializer         dim msgobj msg         dim loginlist new list(of msg)()          msgobj = new msg("mubashir", true)         loginlist.add(msgobj)         msgobj = new msg("yasir", false)         loginlist.add(msgobj)         msgobj = new msg("umar", true)         loginlist.add(msgobj)         dim s string = serializer.serialize(loginlist)         response.write(s)      end sub end class public class msg     dim message string     dim status boolean     sub new(byref messag string, byval stat boolean)            me.message = messag         me.status = stat      end sub end class 

message, status need declare property.

public class msg       public property message() string       public property status() boolean       sub new(byref messag string, byval stat boolean)             me.message = messag             me.status = stat           end sub end class
