kiewic / ftpclient Goto Github PK

Hello! :) I'm student in Republic of Korea. First, My English may hinder your understanding.
I saw the FTP Client in your github. I use Unity-UWP. The ftp client sample project works very well. I'd like to add the ability to import a Ftp file list. What should I do? Please reply :)

I'm using the FTPClient in a Xamarin Forms project aimed solely at Windows UWP. I'm trying to upload an image taken by the camera (but scaled before saving to about 150kB). I'm using the following code to do the upload and I can confirm that the FTP server responds ok after the initial connection, but the upload fails with what looks like a timeout error. Have you seen anything like this?

 private async Task UploadAsync(string filename, string path)
        {
            string ftpUser = "XXXX";
            string ftpPass = "XXXX";
            string ftpUrl = "ftp://xxxxx/" + filename + ".jpg";

            Uri uri = new Uri(ftpUrl);

            FtpClient client = new FtpClient();

            await client.ConnectAsync(
                new HostName(uri.Host),
                 uri.Port.ToString(),
                ftpUser,
                ftpPass);

            byte[] data = null;

            await Task.Run(() =>
             {
                 data = File.ReadAllBytes(path);
             });

             await client.UploadAsync(uri.AbsolutePath, data);
            }
    }

I then get this error after about 25 seconds:

Exception thrown: 'System.Runtime.InteropServices.COMException' in mscorlib.ni.dll
WinRT information: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
