Upload Corrupted

I'm trying upload a file by http. The Upload is OK. Bas de zip file is always corrupted. I've checked the file before upload and i'ts ok.

My code:

var bytes = File.ReadAllBytes(fileToSend);
                    var fileName = Path.GetFileName(fileToSend);

                    RestClient restClient = new RestClient(uploadUrl);
                    RestRequest request = new RestRequest(Method.POST);

                    request.AddHeader("Content-Type", "application/octet-stream");
                    request.Parameters.Clear();
                    request.AddHeader("Authorization", string.Format("Bearer {0}", token.access_token));

                    var meta = "{\"path\": \"/backups/" + fileName + "\",\"mode\": \"overwrite\",\"autorename\": true,\"mute\": false} ";
                    request.AddHeader("Dropbox-API-Arg", meta);

                    request.AddParameter("application/octet-stream", bytes, ParameterType.RequestBody);
                    request.RequestFormat = DataFormat.Json;

                    var response = restClient.Execute(request);

                    return (response.StatusCode == System.Net.HttpStatusCode.OK);

I can't seem to reproduce this. I was just able to upload a zip file using this code and it unzipped properly for me.

How are you checking the resulting zip file?

Yes! The File is ok before upload. Using fiddler a notice that in body I have this: System.byte [].

But if a User addFile to upload a get the error:

Error in call to API function "files/upload": Bad HTTP "Content-Type" header: "multipart/form-data; boundary=-----------------------------28947758029299". Expecting one of "application/octet-stream", "text/plain; charset=dropbox-cors-hack".

Could the problem be this line?

request.RequestFormat = DataFormat.Json;

Your request format is not JSON, and I wonder if that's causing RestSharp to try to convert the byte array to a string (yielding "System.byte []").

Skimming the source code, I actually don't think this is causing your issue, but I'd still recommend removing that line.

I remove that line, but the problem persists. I think need to upload as "application/octet-stream". This make any sense?

Problem solved with the code below.

WebClient client = new WebClient();
                    client.BaseAddress = "https://content.dropboxapi.com/2/";
                    client.Headers.Add("Content-Type", "application/octet-stream");
                    client.Headers.Add("Authorization", string.Format("Bearer {0}", token.access_token));
                    var meta = "{\"path\": \"/backups/" + fileName + "\",\"mode\": \"overwrite\",\"autorename\": true,\"mute\": false} ";
                    client.Headers.Add("Dropbox-API-Arg", meta);
                    var result = client.UploadData("files/upload", WebRequestMethods
                        .Http.Post, bytes);
