Programmatically Upload a File to FTP Server in .Net

[EDN Admin]

The following code snippet could be used to upload files to an FTP site. It uses the FtpWebRequest and FtpWebResponse classes from the System.Net namespace.

Using System.Net:

//Also include any other required namespaces here.

FtpWebRequest ftpRequest;
FtpWebResponse ftpResponse;

try
{
//Settings required to establish a connection with the server
this.ftpRequest = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://ServerIP/FileName"));
this.ftpRequest.Method = WebRequestMethods.Ftp.UploadFile;
this.ftpRequest.Proxy = null;
this.ftpRequest.UseBinary = true;
this.ftpRequest.Credentials = new NetworkCredential("UserName", "Password");

//Selection of file to be uploaded
FileInfo ff = new FileInfo("File Local Path With File Name"); //e.g.: c:\\Test.txt
byte[] fileContents = new byte[ff.Length];

//will destroy the object immediately after being used
using (FileStream fr = ff.OpenRead())
{
fr.Read(fileContents, 0, Convert.ToInt32(ff.Length));
}

using (Stream writer = ftpRequest.GetRequestStream())
{
writer.Write(fileContents, 0, fileContents.Length);
}
//Gets the FtpWebResponse of the uploading operation
this.ftpResponse = (FtpWebResponse)this.ftpRequest.GetResponse();
Response.Write(this.ftpResponse.StatusDescription); //Display response
}
catch (WebException webex)
{
this.Message = webex.ToString();
}
