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 "";
 }
}

希望本文所述对大家的c#程序设计有所帮助。
