我试图登录并查看视频，这也将是有趣的，看看一种方式来赞许或留下评论，帮助赞赏！编辑：错误发生在HttpWebRequest PosterRequest =（HttpWebRequest）WebRequest.Create（YTRedirect）;

这是很多代码，几乎没有任何有关错误的信息。当然，你可以通过一些堆栈跟踪来缩小范围吗？ – spender

这是一个有点硬从代码告诉，但也许仔细检查中包含什么textBox4.Text：

HttpWebRequest PostestRequest = (HttpWebRequest)WebRequest.Create(textBox4.Text);

在黑暗中只是一个拍没有堆栈跟踪。

我还没有读过任何代码，但从它听起来像确保在URL前加入'http：//'。
