問題描述
我搜索并發(fā)現(xiàn)了其他問題，但沒有一個解決我的問題.我正在嘗試使用示例 MSDN 代碼通過 FTP 上傳文件.我收到遠程服務器返回錯誤:(550)文件不可用(例如，找不到文件，無法訪問)錯誤:ftpstream.Close();
I'm searched and found other questions on this but none have solved my issues. I'm trying to upload a file via FTP using sample MSDN code. I get the The remote server returned an error: (550) File unavailable (e.g., file not found, no access) error on this line: ftpstream.Close();
string inputfilepath = @"C:DWF est.txt";
string ftpfilepath = "/abc/def/hij/klm/nop/test.txt";
string ftphost = "my-ser-ver1:2121";
//here correct hostname or IP of the ftp server to be given
string ftpfullpath = "ftp://" + ftphost + ftpfilepath;
FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath);
ftp.Credentials = new NetworkCredential("user", "pass");
//userid and password for the ftp server to given
ftp.KeepAlive = true;
ftp.UseBinary = true;
ftp.Method = WebRequestMethods.Ftp.UploadFile;
FileStream fs = File.OpenRead(inputfilepath);
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();
我已經(jīng)仔細檢查了 URI 是否有空格，但沒有.我可以使用具有相同用戶登錄名的 filezilla 完成此任務.沒有奇怪的默認目錄已經(jīng)是我的 URI 的一部分.可以肯定的一件事是我正在連接到一個 unix 服務器，所以也許我缺少一個設置?
I have double checked the URI for blank spaces and there are none. I am able to complete this task using filezilla with the same user login. There is no oddball default directory that is already part of my URI. One thing for sure is that I am connecting to a unix server so maybe there is a setting I am missing?

推薦答案
這成功了.顯然 CWD 命令行為在從 .NET 3.5 遷移到 4.0 時發(fā)生了變化.
This did the trick. apparently the CWD command behavior changed in the move from .NET 3.5 to 4.0.
