C#获取网页源代码的方法

本文实例讲述了C#获取网页源代码的方法。分享给大家供大家参考。具体如下：

public string GetPageHTML(string url)
{
try
{
 HttpWebRequest wr = WebRequest.Create(url) as HttpWebRequest;
 wr.Method = "get";
 wr.Accept = "*/*";
 wr.Headers.Add("Accept-Language: zh-cn");
 wr.Headers.Add("UA-CPU: x86");
 wr.Headers.Add("Accept-Encoding: gzip, deflate");
 wr.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Embedded Web Browser from: http://bsalsa.com/; InfoPath.2; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)";
 wr.KeepAlive = true;
 wr.ServicePoint.Expect100Continue = false;
 wr.AllowAutoRedirect = false;
 HttpWebResponse wre = wr.GetResponse() as HttpWebResponse;
 StreamReader sreader = new StreamReader(wre.GetResponseStream(), Encoding.GetEncoding("GBK"));
 string sHtml = sreader.ReadToEnd();
 wre.Close();
 return sHtml;
}
catch
{
 return "";
}
}
