Dropbox API Support & Feedback
Find help with the Dropbox API from other developers.
This Code is working fine with console application, but I am getting error with windows service saying Configuration system failed to initialize(System.Configuration.ConfigurationErrorsException was caught)
private static async Task Backup() { using (var dbx = new DropboxClient("<REDACTED>")) { string folder = "DropboxUpload"; string file = "setup.exe"; string content = @"D:\Share\setup.exe"; log.Info("Chunk upload file..."); // Chunk size is 100 mb. const int chunkSize = 2 * 1024 * 1024; using (var stream = new FileStream(content, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)) { int numChunks = (int)Math.Ceiling((double)stream.Length / chunkSize); byte[] buffer = new byte[chunkSize]; string sessionId = null; for (var idx = 0; idx < numChunks; idx++) { log.Info("Start uploading chunk {0}" +idx); var byteRead = stream.Read(buffer, 0, chunkSize); using (MemoryStream memStream = new MemoryStream(buffer, 0, byteRead)) { if (stream.Length <= chunkSize) { // here i am getting exception await dbx.Files.UploadAsync(new CommitInfo("/" +folder + "/" + file), body: memStream); } else if (idx == 0) { var result = await dbx.Files.UploadSessionStartAsync(body: memStream); sessionId = result.SessionId; } else { UploadSessionCursor cursor = new UploadSessionCursor(sessionId, (ulong)(chunkSize * idx)); if (idx == numChunks - 1) { await dbx.Files.UploadSessionFinishAsync(cursor, new CommitInfo("/" + folder + "/" + file), memStream); log.Info("BackUp Completed...!!!"); } else { await dbx.Files.UploadSessionAppendV2Async(cursor, body: memStream); } } } } } } }
