I've just been migrating the systems at work to a new host and it's mostly .NET 2.0 stuff, among the lot is some code which uploads images to a server, which for some strange reason has decided to stop working after 3 years and start uploading gobbledygook instead.
I decided to bypass the old clunky FTP class and just use FtpWebRequest
instead, and thought I'd post here how easy it is (and for future reference! ha).
There are four input variables here: requestUriString
, filePath
, username
, and password
.
requestUriString
should be in the format ftp://10.10.10.10/path/filename.jpg
where the IP is your FTP hostname. The root of this FTP request will be the root of your FTP user account. If you want to upload the image to a directory, include that path in the Uri. Finally, put the desired filename on the end of your request Uri.
filePath
should be the path to your local file, this is used by File.ReadAllBytes( ... ), and is only for getting the data from the local machine.
username
and password
are your FTP login credentials.
The following is an example of how you can quickly and easily upload files using FtpWebRequest
.
public static bool UploadExample(string requestUriString, string filePath,
string username, string password)
{
bool success = true;
try
{
var request = (FtpWebRequest)WebRequest.Create(requestUriString);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential(username, password);
// we read the bytes directly, not with a StreamReader
var fileContents = File.ReadAllBytes(filePath);
request.ContentLength = fileContents.Length;
var requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
// we don't need to use the return type
// unless we want to make checks
request.GetResponse();
}
catch (WebException)
{
success = false;
}
return success;
}
Much easier than using/writing a clunky ol' FTP class yourself, no?
