在Winform下向PHPcms2008后台提交（POST）数据！~或者能够告诉我PHPcms2008提交文章那部分的实现思路

各位高人~我是搞c#的  由于需求要做一个程序 ，能够把一些文章通过PHPcms2008添加文章模块，自动添加！本来在.NET板块提问的 可半天没人理我就跑这里来希望各位高人指点！
具体内容我就直接把.NET板块的问题贴过来了  先谢了  在winform下，准备向PHPcms2008后台文章系统自动提交文章（有个简单的采集器，有文章来源），看了好多关于WebClient和HttpWebRequest提交表单的文章，测试过一部分页面也都能实现。 
但是怎么也不能成功的向PHPcms2008  POST数据。使用HTTP头信息工具查看到的POST值很诡异，没有见过！ 
手动填写标题和正文内容并提交，捕捉到的POST请求如下： 
http://www.xxxxxx.org/admin.php?mod=phpcms&file=content&action=add&catid=24&modelid=1 POST /admin.php?mod=phpcms&file=content&action=add&catid=24&modelid=1 HTTP/1.1
