求C#模拟网页自动注册源代码以研究（如果有图片验证最好。呵呵）。如果有的，发送邮件到[email protected]分，如果多人只能开新贴给分。

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
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
//新建一个CookieContainer来存放Cookie集合
HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create(url);
//新建一个HttpWebRequest
myHttpWebRequest.ContentType="application/x-www-form-urlencoded";
myHttpWebRequest.ContentLength=indata.Length;
myHttpWebRequest.Method="POST";
myHttpWebRequest.CookieContainer=myCookieContainer;
//设置HttpWebRequest的CookieContainer为刚才建立的那个myCookieContainer
Stream myRequestStream=myHttpWebRequest.GetRequestStream();
StreamWriter myStreamWriter=new StreamWriter(myRequestStream,Encoding.GetEncoding("gb2312"));
myStreamWriter.Write(indata);
//把数据写入HttpWebRequest的Request流
myStreamWriter.Close();
myRequestStream.Close(); //关闭打开对象
HttpWebResponse myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();
//新建一个HttpWebResponse
myHttpWebResponse.Cookies=myCookieContainer.GetCookies(myHttpWebRequest.RequestUri);
//获取一个包含url的Cookie集合的CookieCollection
Stream myResponseStream=myHttpWebResponse.GetResponseStream();
StreamReader myStreamReader=new StreamReader(myResponseStream,Encoding.GetEncoding("gb2312"));
outdata=myStreamReader.ReadToEnd();
//把数据从HttpWebResponse的Response流中读出
myStreamReader.Close();
myResponseStream.Close();
Console.WriteLine(outdata);
//显示"登录"
//拿到了Cookie，再进行请求就能直接读取到登录后的内容了
myHttpWebRequest=(HttpWebRequest)WebRequest.Create(url);
myHttpWebRequest.CookieContainer=myCookieContainer;//*
//刚才那个CookieContainer已经存有了Cookie,把它附加到HttpWebRequest中则能直接通过验证
myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();
myHttpWebResponse.Cookies=myCookieContainer.GetCookies(myHttpWebRequest.RequestUri);
myResponseStream=myHttpWebResponse.GetResponseStream();
myStreamReader=new StreamReader(myResponseStream,Encoding.GetEncoding("gb2312"));
outdata=myStreamReader.ReadToEnd();
myStreamReader.Close();
myResponseStream.Close();
Console.WriteLine(outdata);

这个是提交的数据类：
using System.Collections;
using System.IO;
public class RequestData
{
ArrayList arr=new ArrayList();
public RequestData()
{
}
public string GetData()
{
string r="";
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
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
