【Red_angelX】:
自己看HttpWebRequest就可以了

【lovepp2004】:
呵呵。无图片验证无所谓。我想看看怎么实现。呵呵

【tl_pear】:
学习

【zhangliu_521】:
Red_angelX(八戒) 说得对.
各个网站也不一样 很难做到通用

看HttpWebRequest
POST数据

用单独的网站做练习.先搞定一个再说

【mudong303】:
这个东西我做过 就是 HttpWebRequest 很简单 就是设置下head 用post到指定地址就可以啦
不过cookie是个难点，取得图片和取得首页 到登陆完成 cookie要维持，还有不同的网站，登陆前后获取cookie和cookie个数都有所不同

【lovepp2004】:
呵呵。有代码的发奥。我也先去看看httpwebrequest了。哈哈

这个是提交的数据类：

 using System.IO;
 
 public class RequestData

 ArrayList arr=new ArrayList();
 public RequestData()
  {
 
 }

 for(int i=0;i<arr.Count;i++)
  {
 data d=(data)arr[i];
 if(r.Length>0)r+="&";
 r+=d.Field+"="+d.Value;
 }
 return r;
 }
 
 public void AddField(string Field,string Value)
  {
 data a=new data();
 a.Field=Field;
 a.Value=Value;
 
 arr.Add(a);
 }
 
 struct data
  {
 public string Field,Value;
 }
 
 
 }

可以参考

呵呵，都不用c#,直接用javascript就可以了
自己做一个form把要填的内容在form里初始化好，把action设置成目标地址，不停的submit就可以了
