Answer 1

using System.Diagnostics;
using System.IO;
using System.Net;

public static string GetPage(string sURL)
{
// 准备请求...
try
{
string sURL;

WebRequest wrGETURL;
wrGETURL = WebRequest.Create(sURL);

WebProxy myProxy = new WebProxy("myproxy", 80);
myProxy.BypassProxyOnLocal = true;

wrGETURL.Proxy = WebProxy.GetDefaultProxy();

Stream objStream;
objStream = wrGETURL.GetResponse().GetResponseStream();

StreamReader objReader = new StreamReader(objStream);

string sLine = "";

sLine = objReader.ReadLine();
if (sLine != null)
return sLine;

return sLine;

}
catch (Exception ex)
{
return ex.ToString();
}
}

调用该方法传入网址
网页内所有内用将以string方式返回
解析字符串就可以得到你要的信息

post
<form id="form1" method="post" action="default.aspx">
<input id="userName"/>
<input id="password" type="password"/>
<input type="submit" value="提交"/>
get
<form id="form1" method="get" action="default.aspx">
<input id="userName"/>
<input id="password" type="password"/>
<input type="submit" value="提交"/>
注意看地址栏变化
