FTP client in .NET Core

Question

Can I download file / list files via FTP protocol using netcoreapp1.0?

I know, I can use FtpWebRequest or FluentFTP if I target full .net45 framework.

My solution, however, is all based on .NET Standard 1.6 and I don't want to support full framework just to have FTP.

Answer 1

FtpWebRequest is now included to .NET Standard 2.0

FluentFTP library is also compatible with latest .net standard 2.0

Answer 2

FtpWebRequest is now supported in .NET Core 2.0. See GitHub repo

Example usage:

public static byte[] MakeRequest(
    string method, 
    string uri, 
    string username, 
    string password, 
    byte[] requestBody = null)
{
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(uri);
    request.Credentials = new NetworkCredential(username, password);
    request.Method = method;
    //Other request settings (e.g. UsePassive, EnableSsl, Timeout set here)

    if (requestBody != null)
    {
        using (MemoryStream requestMemStream = new MemoryStream(requestBody))
        using (Stream requestStream = request.GetRequestStream())
        {
            requestMemStream.CopyTo(requestStream);
        }
    }

    using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())
    using (MemoryStream responseBody = new MemoryStream())
    {
        response.GetResponseStream().CopyTo(responseBody);
        return responseBody.ToArray();
    }
}

Where the value for the method parameter is set as a member of System.Net.WebRequestMethods.Ftp.
