.Net/C# - getting list of files and then downloading to local drive

I'm back again!

public class Program
    {
        public Logger logger;
        public string localFilePath = @"C:\Users\hbuuutaag\Documents\Code Tests\Test";

            
        public static void Main(string[] args)
        {
            Program program = new Program();
            var task = Task.Run((Func<Task>)program.Run);
            task.Wait();
            
        }

        public async Task Run()
        {
                      
            using (var dbx = new DropboxClient("API TOKEN"))
            {
                logger = NLog.LogManager.GetLogger("logger");

                var full = await dbx.Users.GetCurrentAccountAsync();
                logger.Info("{0} - {1}", full.Name.DisplayName, full.Email);

                var listOfFolders = await dbx.Files.ListFolderAsync(string.Empty, true);

                FolderMetadata dropboxFolderInfo = new FolderMetadata();
                FileMetadata dropboxFileInfo = new FileMetadata();


                foreach (var item in listOfFolders.Entries)
                {
                    try
                    {
                        if (item.IsFile)
                        {
                            dropboxFileInfo = (FileMetadata)item;
                            
                            logger.Info("Processing " + dropboxFileInfo.PathLower.ToString());
                            
                            using (var response = await dbx.Files.DownloadAsync(dropboxFileInfo.PathLower.ToString()))
                            {
                                using (FileStream fileStream = File.Create(localFilePath))
                                {
                                    (await response.GetContentAsStreamAsync()).CopyTo(fileStream);
                                    
                                    logger.Info("Downloaded " + dropboxFileInfo.PathLower.ToString() + " successfully");
                                    
                                }

                            }
                        }
                    }
                    catch (Exception ex)
                    {
                        logger.Error(ex.ToString() + "\t" + dropboxFileInfo);
                    }
                }

I'm iterating through the list of folders successfully, but when I try to pass the file name in to the download handler it's downloading one document with Wingdings galore! Probably missing something super basic...

Thanks in advance!

  • I see you've already found the methods for downloading a file, and it sounds like you are getting the file data successfully. If the download call failed it would raise an exception.

    It sounds like you're having an issue viewing the file though, perhaps due to reading it with an incorrect encoding. How are you viewing/accessing the downloaded file? Depending on the file type/encoding you may need to open it with a different application and/or encoding setting. (I can't offer support for configuring third party applications though of course.)

      Wasn't sure what I was doing incorrectly but managed to get it sorted - the issue was using the .PathLower rather than .Name attributes.

      Thanks again for the quick response Greg! :)
