c#用httpwebrequest实现自动发帖为什么会出现这种情况？中间有continue，源代码在下面，求教育大婶们！

//以下俩句不可缺少

reader.Close();

if (text.IndexOf("发布成功") > 0)
{
MessageBox.Show("发布成功！");
txtTitle.Text = "";
rtxtContent.Text = "";

}
else
{
MessageBox.Show("发布成功！");

}
}

how ???????

[dennis_ben]

看到相应报文中间的100 continue没，这个是不该有的，抓包后发现我的ack都不是一样的，发送一个大的http包是要分片的，分偏后每个片的ack应该是相同的，这样发过去后才知道这是一个包，不然服务器会当成几个包处理，就出现了100 continue，请教大神怎么处理这种情况！

[WM_JAWIN]

System.Net.ServicePointManager.Expect100Continue = false;

执行一次即可。

[dennis_ben]

这是+100continue异常后的结果，但是下面那个是发帖的报文，不是登陆要加的username和pw，显示成功了但找不到帖子，我是在天涯上发的帖子： POST /compose.jsp?item=funinfo&sub=%E5%85%A8%E9%83%A8 HTTP/1.1 Content-Type: application/x-www-form-urlencoded Host: bbs.tianya.cn Content-Length: 224 Connection: Keep-Alive title=test&text=sdgsdgdfgdgd&categoryId=0&blogControl=99&passwordProtedted=&passWord=&editBlogControl=99&postFormId=&newLetterId=&blog_pic_id=&pic_path=&activity=&id=&relative_optype=&isVip=false&jf_vip_em=true&requestToken=HTTP/1.1 200 OK Server: nginx Date: Mon, 11 Aug 2014 07:36:29 GMT Content-Type: text/html; charset=UTF-8 Transfer-Encoding: chunked Connection: close Vary: Accept-Encoding

感谢大家对我学习疑问提供的帮助！

没有Cookie信息

[梦吟情诗]

这种方式没有直接用WebBrowser来发贴好控制

[dennis_ben]

有cookie的，webbrowser拖控件不太好吧！

[WM_JAWIN]

你给出来的数据上没有cookie,你说有的话，那肯定是参数错了

[dennis_ben]

还是用webbrowser做了一个！散分了！
