无法使用monotorrent下载torrent (“无法连接，因为目标计算机主动拒绝”)

Question

我正在尝试使用monotorrent下载torrent。我刚刚从它的github repository下载了一个示例程序，并进行了必要的更改。

它正在尊重的位置上创建大小为0字节的所有文件，并且没有任何进展。在运行堆栈跟踪时，我发现它抛出了一个异常，声明为no connection could be made because the target machine actively refused it。这是一个已处理的异常。我只能在堆栈跟踪中看到这一点。

在我的windows操作系统上，可以通过uTorrent程序下载same torrent。

I have set upped the Git repository for my project here

这是我所有的代码。这是不完整的代码吗？我还需要添加什么？

Answer 1

这可能是因为有问题的跟踪器阻止了像你正在开发的这样的未知客户端。尝试使用Monotorrents自己的工具创建torrent，并将其上传到公共跟踪器，如kat.ph

Answer 2

如果有任何帮助的话，我刚刚成功地将MonoTorrent集成到了我自己的项目中。我基本上放弃了使用网站上的示例代码从头开始编写自己的代码，而是使用git代码库中的SampleClient。我敢打赌，你可以很容易地修改它来满足你的需求，所以试着让它旋转一下。我仍然会说，你得到“连接被拒绝”-errors的原因是因为你试图在跟踪器上不允许torrent-他们不知道的应用程序参与的torrent。您说您已经尝试了几个torrents，但这些可能都使用相同的跟踪器。

HTH。
