How to rename a file after upload

Question

I have to upload file using Ftp protocol on server, and rename uploaded file after uploading.

I can upload it, but don't know how to rename it.

Code looks like this:

FtpWebRequest requestFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServer + "/" + "httpdocs/webroot/" + destination + "/" + fileName));
requestFTP.Proxy = null;

requestFTP.Credentials = new NetworkCredential(ftpUser, ftpPassword);
requestFTP.Method = WebRequestMethods.Ftp.UploadFile;
FileStream fStream = fileInfo.OpenRead();
int bufferLength = 2048;
byte[] buffer = new byte[bufferLength];
Stream uploadStream = requestFTP.GetRequestStream();
int contentLength = fStream.Read(buffer, 0, bufferLength);
while (contentLength != 0)
{
  uploadStream.Write(buffer, 0, contentLength);
  contentLength = fStream.Read(buffer, 0, bufferLength);
}
uploadStream.Close();
fStream.Close();

requestFTP = null;

string newFilename = fileName.Replace(".ftp", "");
requestFTP.Method = WebRequestMethods.Ftp.Rename; // this like makes a problem
requestFTP.RenameTo(newFilename);

Error I'm getting is

Error 2 Non-invocable member 'System.Net.FtpWebRequest.RenameTo' cannot be used like a method.

Solution

RenameTo is a property, not a method. Your code should read:

// requestFTP has been set to null in the previous line
requestFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServer + "/" + "httpdocs/webroot/" + destination + "/" + fileName));
requestFTP.Proxy = null;
requestFTP.Credentials = new NetworkCredential(ftpUser, ftpPassword);

string newFilename = fileName.Replace(".ftp", "");
requestFTP.Method = WebRequestMethods.Ftp.Rename;
requestFTP.RenameTo = newFilename;
requestFTP.GetResponse();

both Method and Rename are strings. They are not functions.

C# doesn't provide a direct rename method. You should copy the file with a new name in the server and delete the old file.

Typically this approach is used to signify to polling applications that the file has finished uploading. The joys of FTP.

Tnx, but I really need to copy file with some tmp name, and after that to rename it to it's native name.

Why not just answer the OP instead?
