c# - Upload directory of files to FTP server using WebClient

Question

I have searched and searched and cannot find a way to do this. I have files in a directory I want to upload. The file names change constantly so I cannot upload by file name. Here is what I have tried.

using (WebClient client = new WebClient())
{
    client.Credentials = new NetworkCredential("User", "Password");
    foreach (var filePath in files)
        client.UploadFile("ftp://site.net//PICS_CAM1//", "STOR", @"PICS_CAM1");
}

But I am getting a compiler error:

The name 'files' does not exist in the current context

Everything I have researched says this should work.

Does anyone have a good way to upload a directory of files via WebClient?

Answer 1

You have to define and set the files. If you wanted to upload all files in a certain local directory, use for example Directory.EnumerateFiles.

Also the address argument of WebClient.UploadFile has to be a full URL to a target file, not just a URL to a target directory.

IEnumerable<string> files = Directory.EnumerateFiles(@"C:localfolder");

using (WebClient client = new WebClient())
{
    client.Credentials = new NetworkCredential("username", "password");

    foreach (string file in files)
    {
        client.UploadFile(
            "ftp://example.com/remote/folder/" + Path.GetFileName(file), file);
    }
}
