C# 一个最简单的GET，返回网页源码

引用：

using System.IO;
using System.Net;

 

代码：

        /// <summary>
        /// Get网址，返回网页源码
         /// </summary>
        /// <param name="webUrl">需要Get的网址。例：http://www.baidu.com</param>
        /// <param name="charset">目标网页的编码集。便：utf-8，gb2312</param>
        /// <returns></returns>
        public string GetWeb(string webUrl, string charset)
        {
            WebRequest request = WebRequest.Create(webUrl);
            WebResponse response = request.GetResponse();
            Stream s = response.GetResponseStream();
            StreamReader sr = new StreamReader(s, Encoding.GetEncoding(charset));//编码格式
             string webHtml =  sr.ReadToEnd();//返回Html
            sr.Dispose();
            sr.Close();
            s.Dispose();
            s.Close();
            return webHtml;
        }

调用：

MessageBox.Show(GetWeb("http://www.baidu.com", "gb2312"));

MessageBox.Show(GetWeb("http://cn.yahoo.com/index.html", "utf-8"));

 

 

 

方法二：

        /// <summary>
        /// Get网址，返回网页源码
        /// </summary>
        /// <param name="url">需要Get的网址。例：http://www.baidu.com</param>
        /// <param name="charset">目标网页的编码集。便：utf-8，gb2312</param>
        /// <returns></returns>
        /// 示例
        /// MessageBox.Show(GetHttpWebRequest("http://www.baidu.com", "gb2312"));
        /// MessageBox.Show(GetHttpWebRequest("http://cn.yahoo.com/index.html", "utf-8"));
        public string GetHttpWebRequest(string url, string charset)
        {
            Uri uri = new Uri(url);
            HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(uri);
            myReq.UserAgent = "User-Agent:Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705";
            myReq.Accept = "*/*";
            myReq.KeepAlive = true;
            myReq.Headers.Add("Accept-Language", "zh-cn,en-us;q=0.5");
            HttpWebResponse result = (HttpWebResponse)myReq.GetResponse();
            Stream receviceStream = result.GetResponseStream();
            StreamReader readerOfStream = new StreamReader(receviceStream, System.Text.Encoding.GetEncoding(charset));
            string strHTML = readerOfStream.ReadToEnd();
            readerOfStream.Close();
            receviceStream.Close();
            result.Close();
            return strHTML;
        }
