Hi Ravi, Use the method below I've created for you: ---------------------------------------------------------- bool uploadFile(string FTPAddress, string filePath, string fileName, string username, string password) { try { FtpWebRequest request = (FtpWebRequest) WebRequest.Create(FTPAddress + "/" + fileName); request.Method = "STOR"; request.Credentials = new NetworkCredential(username, password); request.UseBinary = true; request.Timeout = -1; request.KeepAlive = true; byte[] buffer = File.ReadAllBytes(filePath); Stream requestStream = request.GetRequestStream(); requestStream.Write(buffer, 0, buffer.Length); requestStream.Close(); Console.WriteLine("Uploaded Successfully"); return true; } catch (Exception exception) { //Handle Exception return false; } } ---------------------------------------------------- Haven't tried it yet but I hope I'll work. Mark it as answer if it helps. Cheers!

First we need to import the below namespaces Hide Copy Code using System.IO; using System.Net; Then we need to declare four variables as below: Hide Copy Code String sourcefilepath = “@absolutepath”; // e.g. “d:/test.docx” String ftpurl = “@ftpurl”; // e.g. ftp://serverip/foldername/foldername String ftpusername = “@ftpusername”; // e.g. username String ftppassword = “@ftppassword”; // e.g. password Note: Please replace @absolutepath, @ftpurl, ftpusername, @ftppassword with your actual values. Copy the below code and paste in your class: Hide Copy Code private static void UploadFileToFTP(string source) { try { string filename = Path.GetFileName(source); string ftpfullpath = ftpurl; FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath); ftp.Credentials = new NetworkCredential(ftpusername, ftppassword); ftp.KeepAlive = true; ftp.UseBinary = true; ftp.Method = WebRequestMethods.Ftp.UploadFile; FileStream fs = File.OpenRead(source); byte[] buffer = new byte[fs.Length]; fs.Read(buffer, 0, buffer.Length); fs.Close(); Stream ftpstream = ftp.GetRequestStream(); ftpstream.Write(buffer, 0, buffer.Length); ftpstream.Close(); } catch (Exception ex) { throw ex; } } The final point will be calling the above procedure by using the below code on whatever event you want the operation to be performed. UploadFileToFTP( sourcefilepath ); And we are done... Points of Interest I got an opportunity to learn about the below classes: FtpWebRequest WebRequestMethods NetworkCredential
