Upload file on FTP

Question

I want to upload file from one server to another FTP server and following is my code to upload file but it is throwing an error as:

The remote server returned an error: (550) File unavailable (e.g., file not found, no access).

This my code:

string CompleteDPath = "ftp URL"; string UName = "UserName"; string PWD = "Password"; WebRequest reqObj = WebRequest.Create(CompleteDPath + FileName); reqObj.Method = WebRequestMethods.Ftp.UploadFile; reqObj.Credentials = new NetworkCredential(UName, PWD); FileStream streamObj = System.IO.File.OpenRead(Server.MapPath(FileName)); byte[] buffer = new byte[streamObj.Length + 1]; streamObj.Read(buffer, 0, buffer.Length); streamObj.Close(); streamObj = null; reqObj.GetRequestStream().Write(buffer, 0, buffer.Length); reqObj = null;  

Can you please tell me where i am going wrong?

Answer 1

Please make sure your ftp path is set as shown below.

string CompleteDPath = "ftp://www.example.com/wwwroot/videos/";  string FileName = "sample.mp4";  WebRequest reqObj = WebRequest.Create(CompleteDPath + FileName); 

The following script work great with me for uploading files and videos to another servier via ftp.

FtpWebRequest ftpClient = (FtpWebRequest)FtpWebRequest.Create(ftpurl + "" + username + "_" + filename); ftpClient.Credentials = new System.Net.NetworkCredential(ftpusername, ftppassword); ftpClient.Method = System.Net.WebRequestMethods.Ftp.UploadFile; ftpClient.UseBinary = true; ftpClient.KeepAlive = true; System.IO.FileInfo fi = new System.IO.FileInfo(fileurl); ftpClient.ContentLength = fi.Length; byte[] buffer = new byte[4097]; int bytes = 0; int total_bytes = (int)fi.Length; System.IO.FileStream fs = fi.OpenRead(); System.IO.Stream rs = ftpClient.GetRequestStream(); while (total_bytes > 0) {    bytes = fs.Read(buffer, 0, buffer.Length);    rs.Write(buffer, 0, bytes);    total_bytes = total_bytes - bytes; } //fs.Flush(); fs.Close(); rs.Close(); FtpWebResponse uploadResponse = (FtpWebResponse)ftpClient.GetResponse(); value = uploadResponse.StatusDescription; uploadResponse.Close();

Here are sample code to upload file on FTP Server

    string filename = Server.MapPath("file1.txt");     string ftpServerIP = "ftp.demo.com/";     string ftpUserName = "dummy";     string ftpPassword = "dummy";      FileInfo objFile = new FileInfo(filename);     FtpWebRequest objFTPRequest;      // Create FtpWebRequest object      objFTPRequest = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/" + objFile.Name));      // Set Credintials     objFTPRequest.Credentials = new NetworkCredential(ftpUserName, ftpPassword);      // By default KeepAlive is true, where the control connection is      // not closed after a command is executed.     objFTPRequest.KeepAlive = false;      // Set the data transfer type.     objFTPRequest.UseBinary = true;      // Set content length     objFTPRequest.ContentLength = objFile.Length;      // Set request method     objFTPRequest.Method = WebRequestMethods.Ftp.UploadFile;      // Set buffer size     int intBufferLength = 16 * 1024;     byte[] objBuffer = new byte[intBufferLength];      // Opens a file to read     FileStream objFileStream = objFile.OpenRead();      try     {         // Get Stream of the file         Stream objStream = objFTPRequest.GetRequestStream();          int len = 0;          while ((len = objFileStream.Read(objBuffer, 0, intBufferLength)) != 0)         {             // Write file Content              objStream.Write(objBuffer, 0, len);          }          objStream.Close();         objFileStream.Close();     }     catch (Exception ex)     {         throw ex;     }
