我想用表单应用程序将数据发布到网站。我在上课

     string name = pst.Text;
    WebClientEx Wex = new WebClientEx(name);
在课堂上:

public class WebClientEx : WebClient
    {
        public CookieContainer _cookies = new CookieContainer(); 

       public string Newpost;
       public  WebClientEx(string name)
       {
           name = Newpost;

       }
Im使用此方法发布数据:

public string getPost()
       {         
            WebClientEx client = new WebClientEx();
            CQ dom = CQ.Create(Page);
                  data.Add("value", Newpost);
然而,Newpost总是空的。你能帮我吗?

我想你想做什么

public  WebClientEx(string name)
   {
       Newpost = name;
   }
