public bool Upload(string filename)
{
FileInfo fileInf = new FileInfo(filename);
string uri = "ftp://" + ftpServerIP + "/" + fileInf.Name;
FtpWebRequest reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(uri)); reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword); reqFTP.KeepAlive = false; reqFTP.Method = WebRequestMethods.Ftp.UploadFile; reqFTP.UseBinary = true; reqFTP.ContentLength = fileInf.Length; int buffLength = 2048; byte[] buff = new byte[buffLength];
int contentLen; FileStream fs = fileInf.OpenRead();
try
{
Stream strm = reqFTP.GetRequestStream();
// 每次读文件流的2kb
contentLen = fs.Read(buff, 0, buffLength); // 流内容没有结束
while (contentLen != 0)
{
// 把内容从file stream 写入 upload stream
strm.Write(buff, 0, contentLen); contentLen = fs.Read(buff, 0, buffLength);
} strm.Close();
fs.Close();
return true;
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message, "Upload Error");
return false;
} }
以上代码FTP的URL为IP地址时通过，为域名时，在执行到 Stream strm = reqFTP.GetRequestStream();
时会报以下错误
“应 PASV 命令的请求，服务器返回了一个与 FTP 连接地址不同的地址”
何解？
private static void UploadFile(string localFile)
{
FileInfo fi = new FileInfo(localFile);
FileStream fs = fi.OpenRead();
long length = fs.Length;
FtpWebRequest req = (FtpWebRequest)WebRequest.Create("ftp://" + FtpAddress + FtpRemotePath + fi.Name);
req.Credentials = new NetworkCredential(FtpUid, FtpPwd);
req.Method = WebRequestMethods.Ftp.UploadFile;
req.UseBinary = true;
req.ContentLength = length;
req.Timeout = 10 * 1000;
try
{
Stream stream = req.GetRequestStream();
int BufferLength = 2048;
byte[] b = new byte[BufferLength];
int i;
while ((i = fs.Read(b, 0, BufferLength)) > 0)
{
stream.Write(b, 0, i);
}
stream.Close();
stream.Dispose(); }
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
} }
reqFTP.UsePassive = true;
错误信息：操作超时 reqFTP.UsePassive = false;
错误信息：应 PASV 命令的请求，服务器返回了一个与 FTP 连接地址不同的地址还是 Stream stream = req.GetRequestStream();
这句代码报错
所以出现以下错误：
“应 PASV 命令的请求，服务器返回了一个与 FTP 连接地址不同的地址”请教这个问题该如何解决？

用公网IP请求时，返回的是内网IP，才报：
“应 PASV 命令的请求，服务器返回了一个与 FTP 连接地址不同的地址”这个问题不知道该如何解决？
一使用代理，MS的这个类根本就没有办法使用了。
改用Xceed.Ftp的上传，发现能连接，但无法传送数据。FTP生成0KB的文件用Xceed.Ftp的DEMO试了下 发现连接上后连目录列表都载不下来
