．NET中获取客户端HTML代码

/// <summary>
/// 传入URL返回网页的html代码
/// </summary>
/// <param name="Url">URL</param>
/// <returns></returns>
public static string getUrltoHtml(string Url)
{
errorMsg = "";
try
{
System.Net.WebRequest wReq = System.Net.WebRequest.Create(Url);
// Get the response instance.
System.Net.WebResponse wResp =wReq.GetResponse();
// Read an HTTP-specific property
// Get the response stream.
System.IO.Stream respStream = wResp.GetResponseStream();
// Dim reader As StreamReader = New StreamReader(respStream)
System.IO.StreamReader reader = new System.IO.StreamReader(respStream, System.Text.Encoding.GetEncoding("gb2312"));
return reader.ReadToEnd();

}
catch(System.Exception ex)
{
Chinaz.com

errorMsg = ex.Message ;
}
return "";
}

你可以用这个函数获取网页的客户端的html代码，然后保存到.html文件里就可以了。
