Question

c#通过WebClient获取的网页内容无法显示在控制台上

try {

WebClient wc = new WebClient();
var htmlcode = wc.DownloadString("http://www.anjuke.com/");
var regex = new Regex("<div class=\"cities_boxer\">[\\s\\S]*</div>");
if (regex.IsMatch(htmlcode))
{
var div = regex.Match(htmlcode).Groups["div"].Value;
Console.WriteLine(div);

}

Console.ReadLine();
}
catch(WebException webEx) {

Console.WriteLine(webEx.Message.ToString());

}
我是想把获取到的内容用正则表达式筛选一下，请大神帮忙看看哪里出了问题？

您好，这样的：如果纯粹是下载网页，没必要用socket
WebClient webClient = new
WebClient();
webClient.Credentials =
CredentialCache.DefaultCredentials;
byte[] data = null;
string pageHtml =
"";

try
{
data = webClient.DownloadData(uri);

Encoding loadCode = Encoding.GetEncoding("gb2312");
pageHtml =
loadCode.GetString(data);
}
