How to upload file to FTP server using C#

.Net .Net 3.0 / 3.5 .Net 4.0 Windows Forms

From .net framework 2.0 onwards .net supports FTP operations. Like HttpWebRequest and HttpWebResponse, for FTP operations, FtpWebRequest and FtpWebResponse classes are available, under System.Net namespace. Here is the code snippet, which will help you to upload a file to FTP server, using C#.

string url = "";
var ftpWebRequest = WebRequest.Create(url) as FtpWebRequest;
ftpWebRequest.Method = WebRequestMethods.Ftp.UploadFile;
ftpWebRequest.Credentials = 
    new NetworkCredential("username", "password");
byte[] fileData = GetFileData(@"C:\sample.txt");
using (var requestStream = ftpWebRequest.GetRequestStream())
    requestStream.Write(fileData, 0, fileData.Length);
var response = ftpWebRequest.GetResponse() as FtpWebResponse;


And here is the GetFileData function, which will return byte array from File.

using (var sr = new StreamReader(filename))
    return ASCIIEncoding.ASCII.GetBytes(sr.ReadToEnd());

From the response object, you can get the information about the status of the operation. You can either use StatusCode enum property or StatusDescription property. You can find more information about the status code enumeration on MSDN

Happy Coding :)
