vb.net 2010 - Deserialize JSON keep getting null referance exception -


okay, want deserialize json https://openrct.net/ajax/chat.php. problem no matter try, end null reference exception when try access stored data. have been trying close hour, googling , trying different things, , @ loss how this. please me out.

imports newtonsoft imports newtonsoft.json imports newtonsoft.json.linq imports system.net public class form1 dim ws new webclient  '/ajax/chat.php 'and /ajax/chat.php?latest=55 chat messages after id private sub form1_load(sender object, e eventargs) handles mybase.load  end sub public class postwrapper     public posts() post end class  public class post     public property a() string     public property m() string     public property t() string end class  private sub button1_click(sender object, e eventargs) handles button1.click     dim json string = ws.downloadstring("https://openrct.net/ajax/chat.php")     msgbox(json)     dim postwrapper = jsonconvert.deserializeobject(of postwrapper)(json) ' deserialize array of post objects     msgbox(postwrapper.posts(0).m) 'errors here. end sub end class

thank you.

your object classes deserializing wrong, can use jsonutils.com generating classes json string or url.

here classes json,

public class m     public property id string     public property string     public property m string     public property t string end class  public class example     public property m m()     public property l string end class  dim postwrapper = jsonconvert.deserializeobject(of example)(json) msgbox(postwrapper.m)
