C＃-无法反序列化当前JSON对象

Question

I know there's many threads about this but I don't understand this json output. I have managed to deserialize json from this site before but they differ.

My class looks like this:

public class Bids
{
    public string bids { get; set; }
    public string asks { get; set; }
    public string lastUpdateId { get; set; }
}

Download data:

var depth = w.DownloadString("https://api.binance.com/api/v1/depth?symbol=BTCUSDT&limit=20");

Deserialize:

var book = JsonConvert.DeserializeObject<Bids[]>(depth);

"Cannot deserialize the current JSON object"

Data ( https://api.binance.com/api/v1/depth?symbol=BTCUSDT&limit=20 ) looks like this:

{"lastUpdateId":192569803,"bids":[["6525.40000000","0.62166200",[]],["6524.40000000","0.04081700",[]],["6524.39000000","2.53414400",[]],["6524.13000000","0.53788600",[]],["6523.84000000","3.00000000",[]]],"asks":[["6527.00000000","1.54106400",[]],["6527.51000000","0.37739500",[]],["6527.53000000","0.31064700",[]],["6528.61000000","0.15400000",[]]]}

Answer 1

You can get an idea as to what, your class should look like by using something like the excellent Json2Csharp , you can also use VS paste special 'paste as json..'

Here's how the class should look. dont forget to new up the lists!

public class RootObject
{
  public int lastUpdateId { get; set; }
  public List<List<object>> bids { get; set; }
  public List<List<object>> asks { get; set; }
}

Answer 2

Change your class to this:

 public class RootObject
 {
  public int lastUpdateId { get; set; }
  public List<List<object>> bids { get; set; }
  public List<List<object>> asks { get; set; }
 }

And then DeserializeObject but I am not sure how to access List<List<object>> data!
