I working with a JSON that has this form:

{
   "success": true,
   "message": "OK!",
   "result": [
      {
         "Id": 1,
         "description": "Creacion",
         "name": "name1"
       },
       {
         "Id": 1,
         "description": "Creacion",
         "name": "name2"
       }
   ]
}

I want to get the result array data. I've trying with this:

List<object> list = new List<object>();

public async Task<bool> GetList()
{
     JObject json = new JObject();
     HttpClient http = new HttpClient();
     string urlComplete = "https://..."; // url where the data is obtained
     var response = await http.GetAsync(urlComplete);
     var result = response.Content.ReadAsStringAsync().Result;
     json = JObject.Parse(result);

     ContractStateList  = JsonConvert.DeserializeObject<List<object>>(json.ToString());

     return true;
}

But it throws an error that says Cannot deserialize the current JSON object...

Any help is appreciated.

CodePudding user response：

you have to add to headers a content type that shoult be returned. Try this code

public async Task<List<Result>> GetList()
{
   
    using (var client = new HttpClient())
    {
    var urlAddress = "http://...";

    var contentType = new MediaTypeWithQualityHeaderValue("application/json");
    client.DefaultRequestHeaders.Accept.Add(contentType);
    var response = await client.GetAsync(urlAddress);
    
    if (response.IsSuccessStatusCode)
    {
        var json = await response.Content.ReadAsStringAsync();
        var jsonParsed=JObject.Parse(json);
        var jsonResult=jsonParsed["result"];
        if (jsonResult!=null)
        {
        List<Result> result = jsonResult.ToObject<List<Result>>();
        return result;
        }
    }
  }
return null;
}

and create class

public partial class Result
{
    [JsonProperty("Id")]
    public long Id { get; set; }

    [JsonProperty("description")]
    public string Description { get; set; }

    [JsonProperty("name")]
    public string Name { get; set; }
}
