模拟表单发送数据.
我用下面的方法抓取网页,但是有的网站是看不到参数的,那么在DataPost中就无法写了啊.
HttpWebRequest   MyRequest1   =   (HttpWebRequest)WebRequest.Create( "http://www.anywho.com/qry/wp_fap ");
ServicePointManager.DefaultConnectionLimit   =   5;
string   DataPost1   =   " ";
ASCIIEncoding   myEcoding1   =   new   ASCIIEncoding();
byte[]   Byte1   =   myEcoding1.GetBytes(DataPost1);
MyRequest1.ContentType   =   "application/x-www-form-urlencoded ";
MyRequest1.Method   =   "post ";
MyRequest1.ContentLength   =   DataPost1.Length;
Stream   NewStream1   =   MyRequest1.GetRequestStream();
NewStream1.Write(Byte1,   0,   Byte1.Length);   //sending   request   to   the   web,   if   network   unavailable,   will   jump   to   catch   throws...
NewStream1.Close();


示例网站:http://www.anywho.com/qry/wp_fap
在LastName里输入smith,   zipcode输入11233,search之后它的URL还是http://www.anywho.com/qry/wp_fap,   那么就没有办法获取search之后的网页内容了啊

------解决方案--------------------
比如
<form action= 'url ' method = 'post '>
<td name=name value= 'test '> </td>
<input name=input>
</form>
参数形势就是name=test&input=输入
------解决方案--------------------
用抓包工具直接看发送的数据
