Need help changing max upload speed while seeding

Hey!

I need some help changing the MaxUploadSpeed after/while seeding please.

This is basically the code I am using to start seeding. It’s more like an on demand seeding option so one can click Seed and only then the seeding will start:

private async void button_Seeding_Click(object sender, EventArgs e)
        {
            // Give an example of how settings can be modified for the engine.
            var settingBuilder = new EngineSettingsBuilder
            {
                AllowPortForwarding = true,
                AutoSaveLoadDhtCache = true,
                AutoSaveLoadFastResume = true,
                AutoSaveLoadMagnetLinkMetadata = true,
                AllowLocalPeerDiscovery = true,
                MaximumConnections = 300,

            };

            var torrent = await Torrent.LoadAsync(torrentfile);
            dhtEngine = new DhtEngine(new IPEndPoint(IPAddress.Any, 0));
            TorrentEngine = new ClientEngine(settingBuilder.ToSettings());
            manager = await TorrentEngine.AddAsync(torrent, currentinstalldir);
            manager.TorrentStateChanged += Manager_TorrentStateChanged1;

            await dhtEngine.StartAsync();
            await manager.StartAsync();
        }

private void Manager_TorrentStateChanged1(object sender, TorrentStateChangedEventArgs e)
        {
            while (manager.State == TorrentState.Seeding)
            {
                manager.LocalPeerAnnounceAsync();
                manager.DhtAnnounceAsync();

                label_seeding.Text = manager.State + "... " + ConvertBytesToMegabytes(manager.Monitor.UploadSpeed).ToString("0.00" + " MB/s");
               
            }
        }

From here the torrent starts seeding at full speed as expected, but I would like to make use either a textbox or NumericUpDown in Windows Forms to be able to change the max upload speed while seeding. I just don’t know where and how to implement this. Any help will be much appreciated!

Ah yeah, the joys of writing code in comments instead of an IDE.

    var settingsBuilder = new TorrentSettingsBuilder (manager.Settings);
    settingsBuilder.MaximumUploadSpeed = uploadSpeedInBytesPerSecond;
    var settings = settingsBuilder.ToSettings ();
    await manager.UpdateSettingsAsync (settings);

@uponatime2019 had it right - you need to call .ToSettings() on the builder. Sorry for the confusion!

NOTE: If you constantly create a new ‘SettingsBuilder’ without passing in the old settings, you’ll lose any settings you set previously. You should always initialise the TorrentSettingsBuilder (or EngineSettingsBuilder) with a copy of the settings you want to modify/update. This is typically TorrentManager.Settings or ClientEngine.Settings.

So i used this which i found in another thread:

public async Task UpdateUploadSpeed(int uploadSpeedInBytesPerSecond)
        {
            TorrentSettings setmaxupload = new TorrentSettingsBuilder
            {

                MaximumUploadSpeed = uploadSpeedInBytesPerSecond,

            }.ToSettings();
            await manager.UpdateSettingsAsync(setmaxupload);
        }

The on the numeric up down button I am using this:

private async void numericUpDown1_ValueChanged(object sender, EventArgs e)
        {

            int uploadSpeedInBytesPerSecond = Convert.ToInt32(Math.Round(numericUpDown1.Value * 1000000, 0));
            await UpdateUploadSpeed(uploadSpeedInBytesPerSecond);
        }

I used numericUpDown1.Value * 1000000 to get from bytes to megabytes. Hope that works. I still need to test it though. Running on a mobile network now so cannot test really 😦
