一款asp.net教程 采集远程服务器数据

'using system;
using system.collections.generic;
using system.text;
using system.net;
using system.io;

namespace thief
{
class program
{
static void main(string[] args)
{

try {
webclient mywebclient = new webclient();

mywebclient.credentials = credentialcache.defaultcredentials;//获取或设置用于对向internet资源的请求进行身份验证的网络凭据。

byte[] pagedata = mywebclient.downloaddata("https://www.111cn.net");//从指定网站下载数据

string pagehtml = encoding.default.getstring(pagedata); //如果获取网站页面采用的是gb2312，则使用这句

//string pagehtml = encoding.utf8.getstring(pagedata); //如果获取网站页面采用的是utf-8，则使用这句

console.writeline(pagehtml);//在控制台输入获取的内容

using (streamwriter sw = new streamwriter("c: estouput.html"))//将获取的内容写入文本
{
sw.write(pagehtml);
}

console.readline(); //让控制台暂停,否则一闪而过了
}

catch(webexception webex) {
console.writeline(webex.message.tostring());
}
}
}
