如何在FTP服务器上复制文件？我的目标是将ftp://www.mysite.com/test.jpg复制到ftp://www.mysite.com/testcopy.jpg.要重命名文件,我会使用：
var request = (FtpWebRequest)WebRequest.Create("ftp://www.mysite.com/test.jpg");
request.Credentials = new NetworkCredential(user,pass);
request.Method = WebRequestMethods.Ftp.Rename;
request.RenameTo = "testrename.jpg"
request.GetResponse().Close();
FtpWebResponse resp = (FtpWebResponse)request.GetResponse();
解决方法
试试这个：
static void Main(string[] args)
{
CopyFile("countrylist.csv","MySample.csv","username","password#");
}
public static bool CopyFile(string fileName,string FileToCopy,string userName,string password)
{
try
{
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp.mysite.net/" + fileName);
request.Method = WebRequestMethods.Ftp.DownloadFile;
request.Credentials = new NetworkCredential(userName,password);
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
Upload("ftp://ftp.mysite.net/" + FileToCopy,ToByteArray(responseStream),userName,password);
responseStream.Close();
return true;
}
catch
{
return false;
}
}
public static Byte[] ToByteArray(Stream stream)
{
MemoryStream ms = new MemoryStream();
byte[] chunk = new byte[4096];
int bytesRead;
while ((bytesRead = stream.Read(chunk,chunk.Length)) > 0)
{
ms.Write(chunk,bytesRead);
}
return ms.ToArray();
}
public static bool Upload(string FileName,byte[] Image,string FtpUsername,string FtpPassword)
{
try
{
System.Net.FtpWebRequest clsRequest = (System.Net.FtpWebRequest)System.Net.WebRequest.Create(FileName);
clsRequest.Credentials = new System.Net.NetworkCredential(FtpUsername,FtpPassword);
clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
System.IO.Stream clsStream = clsRequest.GetRequestStream();
clsStream.Write(Image,Image.Length);
clsStream.Close();
clsStream.Dispose();
return true;
}
catch
{
return false;
}
}
这会将文件下载到流中,然后上载它.
