FTP音频文件上传在C＃中不起作用

Question

This is the code I'm using that tries to upload an audio file to the FTP server. It does not work for normal .txt files, neither for .mp3 or .wav files. What am I doing wrong?

using (WebClient client = new WebClient())
{
    client.Credentials = new NetworkCredential(App.FTP_UserID, App.FTP_Password);
    ftpPath = "ftp://" + App.FTP_IP + App.FtpLIDUploadPath + "/";
    client.UploadFile(ftpPath, "STOR", LocalFilePath + LocalFileName);
}

Answer 1

WebClient wc = new WebClient();
wc.Credentials = new NetworkCredential(username, password);
wc.UploadFile("ftp://ftp-server/directory/filename.ext", Local full path);

This should work.
