C# Library - Uploading file to Server By FTP

How to Upload Files with FTP

In my previous article I explained about ASP.Net - Upload file & Download file from folder, Verification and Validation Upload File Type and File Size - ASP .Net. 

In this article I will explain how to upload file to FTP server with valid credentials. To upload a file using ftp you show have following details like FTP URL, FTP UserName, FTP Password. To achieve the file uploading task we have three inbuilt classes in .Net:-

• FtpWebRequest
• WebRequestMethods
• NetworkCredential

Find the source code below:-

string  vStatus = UploadFileToFTP.UploadFileToFTPST(vFileName, vFilePath);

-----

public class UploadFileToFTP

    {

        public static string UploadFileToFTPST(string pFileName, string pFilePath)

        {

            var vFTPLocation = ConfigurationManager.AppSettings["DBServerFTP"]; //<add key="DBServerFTP" value="ftp://192.168.1.108"/>

            var vFTPUser = ConfigurationManager.AppSettings["DBServerFTPUser"]; //<add key="DBServerFTPUser" value="lepton"/>

            var vFTPPwd = ConfigurationManager.AppSettings["DBServerFTPPwd"]; //<add key="DBServerFTPPwd" value="lepton"/>

           

            // Getting object used to communicate with the server.

            FtpWebRequest vFTPRequest = (FtpWebRequest)WebRequest.Create(vFTPLocation + "/" + pFileName);

            vFTPRequest.Method = WebRequestMethods.Ftp.UploadFile;

            // Loggin-In Anonymously and passing user eMailId as password

            vFTPRequest.Credentials = new NetworkCredential(vFTPUser, vFTPPwd);

            // Copy the contents of the file to the request stream.

            StreamReader sourceStream = new StreamReader(pFilePath + "\\" + pFileName);

            byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());

            sourceStream.Close();

            vFTPRequest.ContentLength = fileContents.Length;

            Stream requestStream = vFTPRequest.GetRequestStream();

            requestStream.Write(fileContents, 0, fileContents.Length);

            requestStream.Close();

            FtpWebResponse response = (FtpWebResponse)vFTPRequest.GetResponse();

            return response.StatusDescription;

        } 

    }
