使用WebClient
[font=宋体][size=2][color=#000000] 想要把某个网址存为HTML，[/color][/size][/font][url=http://www.92.la/][font=宋体][color=#000000]上海SEO公司[/color][/font][/url][color=#000000][font=宋体][size=9pt]提示大家可以使用WebClient。[/size][size=9pt] 第一个找到的方法：[/size][/font][/color]
[font=宋体][color=black][size=9pt] string url = [color=black]"[/color][/size][url=http://bafang.in/][size=3][color=black]http://bafang.in[/color][/size][/url][/color][color=black][size=9pt]";[/size][/color][/font]
[size=9pt][font=宋体][color=black][color=black] [/color]string fileName = "Download.html";[/color][/font][/size]
[size=9pt][font=宋体][color=black] WebClient client = new WebClient();[/color][/font][/size]
[size=9pt][font=宋体][color=black] Byte[] htmlData = client.DownloadData(url);[/color][/font][/size]
[size=9pt][font=宋体][color=black] string html = Encoding.UTF8.GetString(htmlData);[/color][/font][/size]
[size=9pt][font=宋体][color=black] StreamWriter sw = new StreamWriter(fileName);[/color][/font][/size]
[size=9pt][font=宋体][color=black] sw.Write(html);[/color][/font][/size]
[size=9pt][font=宋体][color=black] sw.Close();编码设定透过Encoding.UTF8.GetString方法来把byte型态的阵列转换为UTF8编码的String。[/color][/font][/size]
[size=9pt][font=宋体][color=black] 另一种方法：[/color][/font][/size]
[size=9pt][font=宋体][color=black] client.Encoding = Encoding.UTF8;[/color][/font][/size]
[size=9pt][font=宋体][color=black] string html = client.DownloadString(url);[/color][/font][/size]
[size=9pt][font=宋体][color=black] client.Encoding设定的是WebClient上传和下载的String编码设定。[/color][/font][/size]
[size=9pt][font=宋体][color=black] 后来发现还有最短的，不用再另外用StreamWriter存成html：[/color][/font][/size]
[size=9pt][font=宋体][color=black] client.DownloadFile(url, fileName);[/color][/font][/size]
[size=9pt][font=宋体][color=black] 使用WebReguest、HttpWebResponse：[/color][/font][/size]
[size=9pt][font=宋体][color=black] WebRequest request = WebRequest.Create(url);[/color][/font][/size]
[size=9pt][font=宋体][color=black] HttpWebResponse response = (HttpWebResponse)request.GetResponse();[/color][/font][/size]
[size=9pt][font=宋体][color=black] Stream dataStream = response.GetResponseStream();[/color][/font][/size]
[size=9pt][font=宋体][color=black] StreamReader reader = new StreamReader(dataStream);[/color][/font][/size]
[size=9pt][font=宋体][color=black] string html = reader.ReadToEnd();[/color][/font][/size]
[size=9pt][font=宋体][color=black] reader.Close();[/color][/font][/size]
[size=9pt][font=宋体][color=black] dataStream.Close();[/color][/font][/size]
[size=9pt][font=宋体][color=black] response.Close();虽然比较繁複，不过相对的使用WebReguest、HttpWebResponse可以设定比较多参数(Ex:Timeout)，也可以看到完整的流程：对一个URL送出request，把response存为HTML。[/color][/font][/size]
