實現bt下載客戶端，組件有全部源碼和示例，太繁瑣了，就寫了1個簡單處理下載的例子，

組件包含內容挺豐富的，可以自己學著寫。

簡化示例：

private void button1_Click(object sender, EventArgs e)
        {
            string savePath = @"D:\123"; //文件保存路徑
            int dPort = 6881; //端口號
            int maxUp = 10; //最大上傳
            int maxDown = 1000000; //最大下載

            OpenFileDialog ofd = new OpenFileDialog(); //打開種子文件 對話框
            if (ofd.ShowDialog(this) == DialogResult.OK)
            {
                torrent = Torrent.Load(ofd.FileName); //讀入文件
                richTextBox2.AppendText("magnet:?xt=urn:btih:"   Torrent.Load(ofd.FileName).InfoHash.ToString().Replace("-", "")); //轉換為磁力鏈接 顯示

                TorrentFile[] fi = Torrent.Load(ofd.FileName).Files; //文件列表
                for (int i=0;i< fi.Count();i  )   richTextBox3.AppendText(fi[i].Path "\n");
                //下載
                manager = new TorrentManager(torrent, savePath, new TorrentSettings());
                engine = new ClientEngine(new EngineSettings(savePath, dPort));
                engine.Settings.GlobalMaxUploadSpeed = maxUp;
                engine.Settings.GlobalMaxDownloadSpeed = maxDown;
                engine.Register(manager);
                manager.Start();
                //開線程 顯示下載信息
                WorkThread = new Thread(DoWork);
                WorkThread.Start();
            }
        }
