Question to upload file by using Restsharp C# to owncloud server? Thanks

[Carvin Chen]

Hello, everyone!

I am learning the cloud computing and trying to write a little programm that uploads a local file from PC to owncloud server (Ubuntu 16.04). 

I am using visual studio + open source lib restsharp in c# as development environment and have tried many different functions since a week. But it dosent work.., i didnt see any files have been uploaded onto the owncloud server (path), also no error informations...so it seems like unsuccessful..

The big part of my code is below and i really hope, someone could help me to understand, why my code dosent work and maybe some example that work well? 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Text.RegularExpressions;

using System.Threading.Tasks;

using RestSharp;

using RestSharp.Extensions.MonoHttp;

using RestSharp.Authenticators;

using RestSharp.Extensions; //For SaveAs function, example: client.DownloadData(request).SaveAs(path);

using System.IO;

using System.Net;

using System.Globalization;

namespace myOwncloudProj

{

    class Program

    {

        static void Main(string[] args)

        {

            try {

                var client = new RestClient();

                string cloudUsr = "user";

                string cloudPw = "pw";

                string pathToSave = @"D:\path\to\files\";

                client.BaseUrl = new Uri("http://192.168.xxx.xxx/owncloud/remote.php/webdav/");

                client.Authenticator = new HttpBasicAuthenticator(cloudUsr, cloudPw);

                UploadToCloud(client, "tmp.docx", pathToSave);

DownloadToPC(client, "tmp.docx", pathToSave);

            }

            catch (FileNotFoundException ex)

            {

                Console.WriteLine(ex.Message);

            }

            // Verzeichnis existiert nicht

            catch (DirectoryNotFoundException ex)

            {

                Console.WriteLine(ex.Message);

            }

            catch (WebException webExcp)

            {

                // If you reach this point, an exception has been caught.

                Console.WriteLine("A WebException has been caught.");

                // Write out the WebException message.

                Console.WriteLine(webExcp.ToString());

                // Get the WebException status code.

                WebExceptionStatus status = webExcp.Status;

                // If status is WebExceptionStatus.ProtocolError, 

                //   there has been a protocol error and a WebResponse 

                //   should exist. Display the protocol error.

                if (status == WebExceptionStatus.ProtocolError)

                {

                    Console.Write("The server returned protocol error ");

                    // Get HttpWebResponse so that you can check the HTTP status code.

                    HttpWebResponse httpResponse = (HttpWebResponse)webExcp.Response;

                    Console.WriteLine((int)httpResponse.StatusCode + " - "

                       + httpResponse.StatusCode);

                }

            }

            catch (Exception e_cld)

            {

                Console.WriteLine("An error occurred: '{0}'", e_cld);

            }

            Console.ReadLine();

        }

        //Upload file to owncloud server

        public static void UploadToCloud(RestClient ocClient, string fileName, string ocLocal)

        {

            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

            //Check if the file exists on PC

            string localFile = ocLocal + fileName;

            if (File.Exists(localFile) == true)

            {

                Console.WriteLine("local file exits on pc. \n");

                //Check if the file exits on server *********

                //Or upload it directlly

                var requestUpLoad = new RestRequest("/", Method.POST);

                requestUpLoad.AddHeader("Content-Type", "application/octet-stream");

                byte[] dataToUpload = File.ReadAllBytes(localFile);

                requestUpLoad.AddFile("tmpFile", dataToUpload, "tmp.docx");

                Console.WriteLine("Size of file to upload: " + dataToUpload.Length.ToString() + "\n");

                //ocClient.Execute(requestUpLoad);

                var cloudResponse = ocClient.Execute(requestUpLoad);

                Console.WriteLine("Resp: " + cloudResponse.ContentType + "\n");

                Console.WriteLine("Content: " + cloudResponse.Content + "\n");

                Console.WriteLine("Upload has been finished. \n");

            }

            else

            {

                Console.WriteLine("\n" + fileName + " is not found on pc. \n");

            }

        }

    }

}

Hey David,

Trying replace this line

requestUpLoad.AddFile("tmpFile", dataToUpload, "tmp.docx");

Enter code here...

with the following

requestUpLoad.AddParameter("application/octect-stream", dataToUpload, ParameterType.RequestBody);

I recent ran into a similar problem
