c#如何获取网页的内容

Question

套接字。我以前为了刷学校某网站写了个，分享给大家看看~~C#很多东西一个好出就是简单。。using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.IO;namespace httpSeg
{
    class httpWebSeg
    {
        private string url;
        private string postData;
        public httpWebSeg(string u, string p="")
        {
            this.url = u;
            this.postData = p;
        }
        public Stream getResponse(CookieContainer cookies)
        {
            HttpWebRequest request;
            if (postData != "")
            {
                string str = @url + "?" + @postData;
                request = (HttpWebRequest)WebRequest.Create(@str);
            }
            else {
                request = (HttpWebRequest)WebRequest.Create(@url);
            }
            request.CookieContainer = cookies;
            request.Credentials = CredentialCache.DefaultCredentials;
            request.Accept = @"*/*";
            request.Host = @"10.1.1.200:8080";            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream responseStream = response.GetResponseStream();            return responseStream;        }
        public Stream postResponse()
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(@url);
            Encoding encoding = Encoding.GetEncoding("utf-8");
       
            byte[] bytesToPost = encoding.GetBytes(postData);
            request.ContentType = "application/x-www-form-urlencoded";
            request.Method = "POST";
            request.Accept = @"*/*";
            request.Host = @"vote.future.org.cn";
            //request.ContentLength = 5;
            Stream requestStream = request.GetRequestStream();
            requestStream.Write(bytesToPost, 0, bytesToPost.Length);
            requestStream.Close();
            Stream responseStream = request.GetResponse().GetResponseStream();
         
            return responseStream;
        }    }
}这个就是能下载网页代码，然后LZ用XML解析应该就可以了。。

希望楼主可以把源代码发给我研究一下 [email protected]  万二分的感激

Answer 3

 public static string GetHtml(string url, Encoding ec)
        {
            try
            {
                WebRequest request = WebRequest.Create(url);//实例化WebRequest对象
                WebResponse response = request.GetResponse();//创建WebResponse对象
                Stream datastream = response.GetResponseStream();//创建流对象
                StreamReader reader = new StreamReader(datastream, ec);
                string str = reader.ReadToEnd();
                response.Close();
                reader.Close();
                datastream.Close();
                return str;//读取数据
            }
            catch (Exception e)
            { return ""; }
        }
获取html源代码然后正则解析
