I have this array of objects that contains some strings and an array of strings that I want to return from my server:
“[{“original_file_name”:”Plain_HAIR.pdf”,”encrypted_file_name”:”UTTSJG13V1EC46J.pdf”,”is_successful”:true,”message”:””,”email”:”[“testuser@gmail.com”]”,”doctype”:”HAIR”}]”
On my local app, I have a class that looks like this:
public class FileUploadResultViewModel { public string original_file_name { get; set; } public string encrypted_file_name { get; set; } public string is_successful { get; set; } public string message { get; set; } public string email { get; set; } public string doctype { get; set; } } if (res.StatusCode == System.Net.HttpStatusCode.OK) { return JsonConvert.DeserializeObject<List<FileUploadResultViewModel>>(res.Content); } else { return null; }
The issue is that when it comes back to the local app, I get an error saying :
{“Error converting value “[{“original_file_name”:”Plain_HAIR.pdf”,”encrypted_file_name”:”UTTSJG13V1EC46J.pdf”,”is_successful”:true,”message”:””,”email”:”[“testuser@gmail.com”]”,”doctype”:”HAIR”}]” to type ‘System.Collections.Generic.List`1[Uploader.ViewModels.FileUploadResultViewModel]’. Path ”, line 1, position 1521.”}
Am I converting it wrongly or are there some steps missing?
EDIT:
This is how I define the object on the server:
$object = (object) [ 'original_file_name' => $item["original_file_name"], 'encrypted_file_name' => $item["file_name"], 'is_successful' => true, 'message' => '', 'email' => NULL, 'doctype' => $item["doctype"] ]; array_push($myArray, $object); $this->response(json_encode($myArray));
EDIT 2: Showing the method to retrieve the json result
public FileUploadResultViewModel Upload(List<FileUploadViewModel> sdvm) { var js = JsonConvert.SerializeObject(sdvm); RestClient client = new RestClient(); var link = url; var username = username; var password = password; client.BaseUrl = new Uri(link); client.Authenticator = new HttpBasicAuthenticator(username, password); RestRequest request = new RestRequest(); request.AddJsonBody(sdvm); request.Method = Method.POST; var res = client.Execute(request); if (res.StatusCode == System.Net.HttpStatusCode.OK) { return JsonConvert.DeserializeObject<FileUploadResultViewModel>(res.Content); } else { return null; } }

Update:
Final solution was that there was a json_encode
too much.
On the line before var res = client.Execute(request);
, add this:
request.OnBeforeDeserialization = resp => { resp.ContentType = "application/json"; };
This is working:
var json = @"[{""original_file_name"":""Plain_HAIR.pdf"",""encrypted_file_name"":""UTTSJG13V1EC46J.pdf"",""is_successful"":true,""message"":"""",""email"":""[""testuser@gmail.com""]"",""doctype"":""HAIR""}]"; var convertedInstance = JsonConvert.DeserializeObject<List<FileUploadResultViewModel>>(json);
And surrounding with "
is also working
var json2 = @"""[{""original_file_name"":""Plain_HAIR.pdf"",""encrypted_file_name"":""UTTSJG13V1EC46J.pdf"",""is_successful"":true,""message"":"""",""email"":""[""testuser@gmail.com""]"",""doctype"":""HAIR""}]"""; var convertedInstance2 = JsonConvert.DeserializeObject<List<FileUploadResultViewModel>>(json);
