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。
