Upload file to server using FTP

Introduction

using this article i have demonstrate how to upload text file on ftp server. 

Background

I am programmer having 3+ year of experience in web as well as window development.

Using the code 

upload a file using FTP details, one should know the server’s FTP URL, FTP username and FTP password and specific FTP folder which is hold all file in ftp  

I have set all ftp and file details from database. Code given blow 

IDictionary<string, string> ftpDetails = new Dictionary<string, string>();  
ftpDetails.Add("FTPUrl", dataSet.Tables[2].Rows[0]["FtpUrl"].ToString());
ftpDetails.Add("FTPUserId", dataSet.Tables[2].Rows[0]["FtpUserId"].ToString());
ftpDetails.Add("FTPPassword", dataSet.Tables[2].Rows[0]["FtpPassword"].ToString());
ftpDetails.Add("FTPFolderName", dataSet.Tables[2].Rows[0]["FolderName"].ToString());
ftpDetails.Add("FileName", "FileName"); 
 

All value set in dictonary objects after then call method which is implented the ftp uploading funtionality.

UploadFileOnFtp(ftpDetails);

I have implemented the funtionality for file uploading on ftp server.

private static void UploadFileOnFtp(IDictionary<string, string> ftpDetails)
       {
           try
           {
               FileInfo fileInfo = new FileInfo(ftpDetails["FileName"]);
               string uri = "ftp://" + ftpDetails["FTPUrl"] + "/" + ftpDetails["FTPFolderName"] + "/" + fileInfo.Name;
               FtpWebRequest  ftpWebRequest = (FtpWebRequest)FtpWebRequest.Create(new Uri(uri));
               ftpWebRequest.Credentials = new NetworkCredential(ftpDetails["FTPUserId"], ftpDetails["FTPPassword"]);
               ftpWebRequest.KeepAlive = false;
               ftpWebRequest.Method = WebRequestMethods.Ftp.UploadFile;
               ftpWebRequest.UseBinary = true;
               ftpWebRequest.ContentLength = fileInfo.Length;
               int buffLength = 2048;
               byte[] buff = new byte[buffLength];
               int contentLen;
               FileStream fileStream = fileInfo.OpenRead();
               Stream stream = ftpWebRequest.GetRequestStream();
               contentLen = fileStream.Read(buff, 0, buffLength);
               while (contentLen != 0)
               {
                   stream.Write(buff, 0, contentLen);
                   contentLen = fileStream.Read(buff, 0, buffLength);
               }
               stream.Close();
               fileStream.Close();

           }
           catch (Exception ex)
           {
               LogManager.WriteErrorLog(ex);
               throw;
           }
           finally
           {
               LogManager.WriteTraceLog(trace.ToString());
           }
       }   

The final process whichwill be calling the above procedure by using the below code on whatever event you want the operation to be performed
