JsonConvert deserialize only Class fields

Question

This is json:

{
    "odata.metadata": ".....",
    "value": [
        {
            "AbsEntry": 10,
            "ItemNo": "....",
            "UoMEntry": -1,
            "Barcode": "2000000000022",
            "FreeText": "Ean13"
        }
    ]
}

This is class:

public class BarCode
{
     public int AbsEntry { get; set; }
     public string ItemNo { get; set; }
     public string Barcode { get; set; }
     public string FreeText { get; set; }
 }

This method return null:

BarCode barcode = JsonParser.DeserializeObjcet<BarCode>(json);

Are there any properties or other that can cause the call DeserializeObject to deserialize me only the fields of my classes (the names are exactly those of the Json)?

Answer 1

You need to create class like below not BarCode

public class Value
{
 public int AbsEntry { get; set; }
 public string ItemNo { get; set; }
 public int UoMEntry { get; set; }
 public string Barcode { get; set; }
 public string FreeText { get; set; }
}

or you can change the JSON format

"BarCode": [
        {
            "AbsEntry": 10,
            "ItemNo": "....",
            "UoMEntry": -1,
            "Barcode": "2000000000022",
            "FreeText": "Ean13"
        }
    ]

Answer 2

The structure of your class should match the structure of your JSON if you want the deserialization to succeed.

If you want a partial deserialization e.g. only deserializing the values property into your class you can use this code:

JObject jObject = JObject.Parse(json);
BarCode barcode = jObject["values"].Children().First().ToObject<BarCode>();

With this solution you don't need to refactor your class or adding a new one.
