JSON Question

Deserialize of JSON string containg key,value pair and some values without keys


string strJson={"build":42606,"torrents": [["3C50FB27DB1469EFFD2F7BEAB9997D6425416380",136,"Westworld.S01E02.720p.HDTV.x265.ShAaNiG.mkv",314721982,1000,314721982,12042240,38,0,0,0,"",0,0,0,0,65536,-1,0,"","","Finished

"label": [],"torrentc": "928729876"
,"rssfeeds": []
,"rssfilters": []
}


this is the JSON string that i tried to deserialize. this contain key,value pairs(


"build":42606,"torrentc": "928729876"


) and some part contain only values without keys(


"torrents:[["3C50FB27DB1469EFFD2F7BEAB9997D6425416380",136,"Westworld.S01E02.720p.HDTV.x265.ShAaNiG.mkv",314721982,1000,314721982,12042240,38,0,0,0,"",0,0,0,0,65536,-1,0,"","","Finished

16.4 %","5",1475985070,0,"","C:\Users\Ubhaya Kalanamiththa\Downloads\The Green Hornet (2011)",0,"E156BE18"]]


).

i tried to used Newston JSON Converter.
here is my code

TORRENTLIST list = JsonConvert.DeserializeObject<TORRENTLIST>(strJson);

public class TORRENTLIST
{
public int build { get; set; }
public label label { get; set; }
public List<torrents> torrents { get; set; }
public string torrents { get; set; }
}

public class torrents
{
public string HASH { get; set; }
public int STATUS { get; set; }
public string NAME { get; set; }
public int size { get; set; }
public int PERCENT_PROGRESS { get; set; }
public int DOWNLOADED { get; set; }
public int UPLOADED { get; set; }
public int RATIO { get; set; }
public int UPLOAD_SPEED { get; set; }
public int DOWNLOAD_SPEED { get; set; }
public int ETA { get; set; }
public string LABEL { get; set; }
public int PEERS_CONNECTED { get; set; }
public int PEERS_IN_SWARM { get; set; }
public int SEEDS_CONNECTED { get; set; }
public int SEEDS_IN_SWARM { get; set; }
public int AVAILABILITY { get; set; }
public int TORRENT_QUEUE_ORDER { get; set; }
public int REMAINING { get; set; }
}

public class label
{
public string LABEL { get; set; }
public int TORRENT_IN_LABEL { get; set; }
}


when i run this code i'm getting this error code


Additional information: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'torrents' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.


what is the way to fix this error in c#?

Answer

Your JSON string doesn't validate. That's because the path strings you have. You have to use double backslashes there, so this would be a valid JSON:

{
"build": 42606,
"torrents": [
    ["3C50FB27DB1469EFFD2F7BEAB9997D6425416380", 136, "Westworld.S01E02.720p.HDTV.x265.ShAaNiG.mkv", 314721982, 1000, 314721982, 12042240, 38, 0, 0, 0, "", 0, 0, 0, 0, 65536, -1, 0, "", "", "Finished 100.0 %", "1", 1475885736, 1475886039, "", "C:\\Users\\Ubhaya Kalanamiththa\\Downloads", 0, "57FA52E7"],
    ["D9CD68E5AC219D574C1BA2714EF32F6C9BC14AB6", 136, "The Green Hornet (2011)", 787687134, 164, 129400832, 11829248, 91, 0, 0, 0, "", 0, 0, 0, 0, 10545, 1, 658286302, "", "", "Stopped 16.4 %", "5", 1475985070, 0, "", "C:\\Users\\Ubhaya Kalanamiththa\\Downloads\\The Green Hornet (2011)", 0, "E156BE18"]
],
"label": [],
"torrentc": "928729876",
"rssfeeds": [],
"rssfilters": []
}  

Notice the path strings "C:\\Users\\Ubhaya Kalanamiththa\\Downloads"

This would be the class you'll need to deserialize it using JSON.NET:

public class TORRENTLIST
{
    public int build { get; set; }
    public List<List<object>> torrents { get; set; }
    public List<object> label { get; set; }
    public string torrentc { get; set; }
    public List<object> rssfeeds { get; set; }
    public List<object> rssfilters { get; set; }
}
