将录音上传到ftp

Question

I need to upload audio files recorded from my application .I am unable to upload aac files to ftp. Here is my code to upload

FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(myftppath);

                ftp.Credentials = new NetworkCredential(username,password);

                ftp.UseBinary = true;
                ftp.Method = WebRequestMethods.Ftp.UploadFile;

                FileStream fs = File.OpenRead(audioFilePath);

                byte[] buffer = new byte[fs.Length];
                fs.Read(buffer, 0, buffer.Length);

                fs.Close();

                Stream ftpstream = ftp.GetRequestStream();
                ftpstream.Write(buffer, 0, buffer.Length);
                ftpstream.Close();
                ftpstream.Flush();

The code works for uploading other files like txt,png,mp3 etc but not for aac files. Please help

Answer 1

Your code seems to be correct. You may try this,

1. If you are running the app on simulator,check if your OS has permission to write file to ftp.
2. Install your app on real device and try to upload using the same code.

If none works then find out the exact cause of error using try block.
