模拟登陆过程应该很简单，由WebBrowser自动完成（前提myWebBrowser.Navigate参数组成好就行了），难的就是怎么知道获取所有的好友ID，这个很困难，不过可以通过Fiddler抓包很容易就知道了，这里就是一个页面存放者该ID( GetFriends)下所有好友的ID。

自动留言，虽此留言板是通过JS动态生成的，查看源码没有留言文本框以及提交ID，但通过Ie developer toolbar可以看出此文本框是有ID的，而且WebBrowser可以获取由JS动态生成的这些留言本的所有的ID，可以正常的使用HtmlElement获取Document元素，然后执行OnClick事件提交表单。

此方法还有个就是采用了多线程处理循环事件，因为我们提交表单，需要在WebBrowser成功加载完才能执行。

System.Threading.AutoResetEvent obj = new System.Threading.AutoResetEvent(false);

public void btnSubmit_Click(object sender, EventArgs e)

{

obj.Reset();

while (obj.WaitOne(100, false) == false) { Application.DoEvents(); }

//WaitOne 在子程序执行Set才继续执行循环

}
