Introduction:
In this article,i am going to explain about how to copying/Transfering files from local machine to netftp server.

Main:

Sample Code,

string netftpUserID1 = "";//netftp UserId string netftpPassword1=""//netftp password FileInfo fileInf = new FileInfo(C:\Sample.txt); string uri = "ftp://" + netftp.netprogramminghelp.com + "/" + fileInf.Name; netftpWebRequest reqnetftp; // Create netftpWebRequest object from the Uri provided reqnetftp = (netftpWebRequest)netftpWebRequest.Create (new Uri("netftp://" + netftp.netprogramminghelp.com + "/" + fileInf.Name)); // Provide the WebPermission Credintials reqnetftp.Credentials = new NetworkCredential(netftpUserID1, netftpPassword1); // By default KeepAlive is true, where the control connection // is not closed after a command is executed. reqnetftp.KeepAlive = false; // Specify the command to be executed. reqnetftp.Method = WebRequestMethods.netftp.UploadFile; // Specify the data transfer type. reqnetftp.UseBinary = true; // Notify the server about the size of the uploaded file reqnetftp.ContentLength = fileInf.Length; int buffLength = 500447300; byte[] buff = new byte[buffLength];   int contentLen; // Opens a file stream (System.IO.FileStream) to read the file // to be uploaded FileStream fs = fileInf.OpenRead(); try { // Stream to which the file to be upload is written Stream strm = reqnetftp.GetRequestStream(); // Read from the file stream 2kb at a time contentLen = fs.Read(buff, 0, buffLength); // Till Stream content endswhile (contentLen != 0) {   // Write Content from the file stream to the netftp Upload // Stream   strm.Write(buff, 0, contentLen); contentLen = fs.Read(buff, 0, buffLength); }   strm.Close(); fs.Close();   } catch (Exception ex) {   throw new Exception(ex.Message); }

Conclusion:
Hope this helps,
Happy Coding.
