C# .NET - FtpRequest

My task is , read the data from temp file and copy to FTPpath.
when the file is getting copied to FTP, it should be readonly or not accesible ( other source sholudn't be able to access the file). once the file is copied to FTP it can be accessed by other source .
I have tried both UsePassive =true& false, KeepAlive =true& false


FtpWebRequest reqFTP;
reqFTP.UsePassive = false;
reqFTP.KeepAlive = true;

The Properties u have used , should work m not sure why it is not working for u , could u please post the complete code if possible, alternatively u can go through these post from different site , having complete step by step process

The UsePassive command doesn't work for the purpose you want it to. It simply requests the FTP server that you connected at first place, to listen on a port instead of the command. 

See MSDN for more information on this command - http://msdn.microsoft.com/en-us/library/system.net.ftpwebrequest.usepassive.aspx

Back to your original question, it is for your clients to decide when they should download the files from the ftp server (perhaps, a text file indicating that the upload is complete?). You can only mark it readonly with the default read access though. 

A simpler option over the FTPRequest is using the WebClient. See the following example. 

using (System.Net.WebClient client = new System.Net.WebClient())
{
      client.Credentials = new System.Net.NetworkCredential("scott", "pass123));
      client.UploadFile(Path.Combin(ftpServer, filename), "upload", filename);
}

Hope this helps.
