Question

我写下面的函数将文件上传到ftp.it正常工作但我需要上传文件名。我认为ftp服务器应该写文件名作为回应，我是对的吗？

   public static string UploadFileToFTP(string source,string destination)
{
    string filename = Path.GetFileName(source);
    string ftpfullpath = @ConfigurationManager.AppSettings["ftp_url"].ToString();
    FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath+@destination);
    ftp.Credentials = new NetworkCredential(ConfigurationManager.AppSettings["ftp_user"].ToString(), ConfigurationManager.AppSettings["ftp_pass"].ToString());
    string[] jj = ftp.Headers.GetValues(0);
    ftp.KeepAlive = true;
    ftp.UseBinary = true;
    ftp.Method = WebRequestMethods.Ftp.UploadFileWithUniqueName;

    FileStream fs = File.OpenRead(@source);
    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();
    FtpWebResponse response = (FtpWebResponse)ftp.GetResponse();

    return ConfigurationManager.AppSettings["ftp_http_url"].ToString() + @destination + "/" + response.ToString();//response.?
}

Answer 1

您只需阅读Response信息流

即可

string fileName = new StreamReader(response.GetResponseStream()).ReadToEnd();

或更好

string fileName;
using(s = new StreamReader(response.GetResponseStream())) {
    fileName = s.ReadToEnd();
}

我不确定为什么你全部“裸露”并且使用WebClient，这可以通过使用byte[]的三个LOC解决，它返回using (WebClient webClient = new WebClient()) { webClient.Credentials = new NetworkCredential( ConfigurationManager.AppSettings["ftp_user"].ToString(), ConfigurationManager.AppSettings["ftp_pass"].ToString()); byte[] response = webClient.UploadFile("ftp://address.toserver.com", WebRequestMethods.Ftp.UploadFileWithUniqueName, "PathToLocalFile"); var fileName = Encoding.UTF8.GetString(response); }响应：< / p>
