downloadString 乱码

[sohighthesky]

using (WebClient web = new WebClient())
                {
                    data =web.DownloadString(url);
                }

这个当url为http://www.baidu.com是就是好的，但是http://www.cnblogs.com/却是乱码
有没办法解决？
想得到是网页的源代码，或者不用WebClient 这个类也可以

using (WebClient web = new WebClient())
{
    web.Encoding = System.Text.Encoding.UTF8;
    data =web.DownloadString(url);
}

WebRequest hwr = WebRequest.Create(@"http://www.cnblogs.com") ;
            HttpWebResponse hwp = hwr.GetResponse() as HttpWebResponse;
            string text;
            StreamReader sr;
            string code = hwp.ContentType;
            //得到编码了
            code = code.Split('=')[1];
            Stream rep = hwp.GetResponseStream();
            switch (code)
            {
                case "utf-8":
                     sr= new StreamReader(rep, Encoding.UTF8);
                     text = sr.ReadToEnd();
                    break;
                case "gb2312":
                    sr = new StreamReader(rep, Encoding.GetEncoding("gb2312"));
                    text = sr.ReadToEnd();
                    break;
                default:
                    break;
            }

改一下。。。不应该用switch的。。。

WebRequest hwr = WebRequest.Create(@"http://www.baidu.com") ;
            HttpWebResponse hwp = hwr.GetResponse() as HttpWebResponse;
            string text;
            StreamReader sr;
            string code = hwp.ContentType;
            //得到编码了
            code = code.Split('=')[1];
            Stream rep = hwp.GetResponseStream();
            sr = new StreamReader(rep, Encoding.GetEncoding(code));
            text = sr.ReadToEnd();

C# code

WebRequest hwr= WebRequest.Create(@"http://www.cnblogs.com") ;
HttpWebResponse hwp= hwr.GetResponse()as HttpWebResponse;string text;
StreamReader sr;string code= hwp.ContentType;//得到编码了 code= code.Split('=')[1];
Stream rep= hwp.GetResponseStream();switch (code)
{case"utf-8":
sr=new StreamReader(rep, Encoding.UTF8);
text= sr.ReadToEnd();break;case"gb2312":
sr=new StreamReader(rep, Encoding.GetEncoding("gb2312"));
text= sr.ReadToEnd();break;default:break;

用webbrower最好，能够自动识别编码，

webrequest webclient都需要设置编码，但是网站编码不是统一的，所以有的会有乱码。

乱码一般都是编码不同引起的

[wzp144650]

为什么不用webrequset呀？

[/Quote]是个人都知道

[wuyq11]

WebClient client = new WebClient();
string s = client.DownloadString("http://www.cnblogs.com");
Console.WriteLine(Encoding.UTF8.GetString(Encoding.Default.GetBytes(s)));
获取网页字符编码
Match m= Regex.Match(s, "<meta([^<]*)charset=([^<]*)\"", RegexOptions.IgnoreCase | RegexOptions.Multiline);
string CharSet = m.Groups[2].Value;
