Asp.net json deserialization

Question

I have problem with deserialization server response in JSON format. I use JavaScriptSerializer but I am getting null from it.

{"0":{"Name":"BusinessSegmentFilter","Items":{"0":{"ItemName":"1650","IsEditable":false,"IsClicked":false,"IsSelected":false},"1":{"ItemName":"1457","IsEditable":false,"IsClicked":false,"IsSelected":false},"2":{"ItemName":"1649","IsEditable":false,"IsClicked":false,"IsSelected":false},"3":{"ItemName":"1651","IsEditable":false,"IsClicked":false,"IsSelected":false},"4":{"ItemName":"4480","IsEditable":false,"IsClicked":false,"IsSelected":false},"5":{"ItemName":"1692","IsEditable":false,"IsClicked":false,"IsSelected":false},"6":{"ItemName":"4012","IsEditable":false,"IsClicked":false,"IsSelected":false},"7":{"ItemName":"4198","IsEditable":false,"IsClicked":false,"IsSelected":false},"8":{"ItemName":"1652","IsEditable":false,"IsClicked":false,"IsSelected":false}},"MaxValue":null,"MinValue":null},"1":{"Name":"BusinessSegmentFilter","Items":{"0":{"ItemName":"1650","IsEditable":false,"IsClicked":false,"IsSelected":false},"1":{"ItemName":"1457","IsEditable":false,"IsClicked":false,"IsSelected":false},"2":{"ItemName":"1649","IsEditable":false,"IsClicked":false,"IsSelected":false},"3":{"ItemName":"1651","IsEditable":false,"IsClicked":false,"IsSelected":false},"4":{"ItemName":"4480","IsEditable":false,"IsClicked":false,"IsSelected":false},"5":{"ItemName":"1692","IsEditable":false,"IsClicked":false,"IsSelected":false},"6":{"ItemName":"4012","IsEditable":false,"IsClicked":false,"IsSelected":false},"7":{"ItemName":"4198","IsEditable":false,"IsClicked":false,"IsSelected":false},"8":{"ItemName":"1652","IsEditable":false,"IsClicked":false,"IsSelected":false}},"MaxValue":null,"MinValue":null}}

 var resposne = serializer.Deserialize<AjaxResposne>(eventArgument);
 public class AjaxResposne
 {
 public string Name { get; set; }
 public List<Item> Items { get; set; }
 public string MaxValue { get; set; }
 public string MinValue { get; set; }
}
public class Item
{
 public string ItemName { get; set; }
 public bool IsEditable { get; set; }
 public bool IsClicked { get; set; }
 public bool IsSelected { get; set; }
}

Answer 1

Your json contains property names like "0", "1" etc., So you have to use some tricks to deserialize correctly (Dictionary<string,SomeClass>).

var obj = new JavaScriptSerializer()
 .Deserialize<Dictionary<string,ItemCollection>>(json);

---

public class ItemCollection
{
 public string Name { get; set; }
 public string MaxVlaue { get; set; }
 public string MinValue { get; set; }
 public Dictionary<string, Item> Items { get; set; }
}
public class Item
{
 public string ItemName { get; set; }
 public bool IsEditable { get; set; }
 public bool IsClicked { get; set; }
 public bool IsSelected { get; set; }
}

Answer 2

Your JSON is wrong, not regarding syntax, but regarding the way the JavaScriptSerializer expects your lists to be structured.

Remove the indexes and use a regular array and everything works as expected:

{
 "Name": "BusinessSegmentFilter",
 "Items": [
 {
 "ItemName": "1650",
 "IsEditable": false,
 "IsClicked": false,
 "IsSelected": false
 }
 ],
 "MaxValue": null,
 "MinValue": null
}
