请教：如何用C#获取网页显示的内容？ （不是获取html代码！）
我想用C#获取某个网页上显示的内容（注：不是获取html代码）



我已经用vbs实现了这样的功能,源码如下：

Const ForWriting = 2
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objTextFile = objFSO.OpenTextFile("Kaijiang_xj.txt", ForWriting, True)
Set objIE = CreateObject("InternetExplorer.Application")
'objIE.visible = True
objIE.Navigate("http://www.xjflcp.com/ssc/")
Do While objIE.ReadyState<>4
Loop
Set objDoc = objIE.Document
Set aTables = objDoc.getElementsByTagName("Table")
For Each objTable In aTables
objTextFile.WriteLine objTable.Innertext
Next
objTextFile.Close
objIE.Quit

另存位*.vbs,执行即可。



请问，怎么用C#实现这样的功能？

[解决办法]

C# code

WebBrowser web = new WebBrowser();            web.Navigate("http://www.xjflcp.com/ssc/");            web.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(web_DocumentCompleted);void web_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)        {            WebBrowser web = (WebBrowser)sender;            HtmlElementCollection ElementCollection = web.Document.GetElementsByTagName("Table");            foreach (HtmlElement item in ElementCollection)            {                 File.AppendAllText("Kaijiang_xj.txt", item.InnerText);            }        }
[解决办法]
C# code
//先取网页HTMLstring r; WebRequest myReq = WebRequest.Create("网页URL"); WebResponse myRes = myReq.GetResponse(); Stream resStream = myRes.GetResponseStream(); StreamReader sr = new StreamReader(resStream, Encoding.Default); StringBuilder sb = new StringBuilder(); while ((r = sr.ReadLine()) != null) { sb.Append(r); } //再利用正则表达string regexStr = @"正则表达式"; Match mc = Regex.Match(sb.ToString(), regexStr, RegexOptions.IgnoreCase); this.Label1.Text = mc.Groups[1].Value; myRes.Close();
[解决办法]
C# code
WebClient web = new WebClient();byte [] buffer = web.DownloadData("http://www.xjflcp.com/ssc/");string html = System.Text.UTF8Encoding.UTF8.GetString(buffer);
