C# HttpWebResponse和编码（奇怪字符）

我的问题是，当我将帖子发送到表单时，它们是错误的字符

我发送扩展ASCII码：

█████████

发帖后我得到：

–––ˆ–ˆ–ˆ–ˆ–ˆ–ˆ–ˆ–ˆ

我的代码：

req = (HttpWebRequest)HttpWebRequest.Create("http://forum.com/);
    req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705;)";
    req.Method = "POST";
    req.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
    req.Headers.Add("Accept-Language: en-us,en;q=0.5");
    req.Headers.Add("Accept-Encoding: gzip,deflate");
    req.Headers.Add("Accept-Charset: ISO-8859-1;q=0.7,*;q=0.7");
    req.KeepAlive = true;
    req.Headers.Add("Keep-Alive: 300");
    req.Referer = "http://www.google.com/";

    req.ContentType = "application/x-www-form-urlencoded";
    req.CookieContainer = _cookieJar;
    req.ServicePoint.Expect100Continue = false;

    byte[] bytedata =
        Encoding.GetEncoding("iso-8859-1").GetBytes("subject=" + HttpUtility.UrlEncode(subject.Replace("_", " ")) +
                           "&description=" + HttpUtility.UrlEncode(description));

    Stream requestStream = req.GetRequestStream();
    requestStream.Write(bytedata, 0, bytedata.Length);
    requestStream.Close();

    try
    {
        response = (HttpWebResponse)req.GetResponse();
    }
    catch (Exception ex)
    {
        MessageBox.Show("oh noes...");
    }
                break;

现场编码为ISO-8859-1。

我做到了：

private string Encode(string text)
        {
            text = HTMLEncodeSpecialChars(text);
            return HttpUtility.UrlEncode(text);
        }

        public string HTMLEncodeSpecialChars(string text)
        {
            StringBuilder sb = new System.Text.StringBuilder();
            foreach (char c in text)
            {
                if (c > 127) // special chars
                    sb.Append(String.Format("&#{0};", (int)c));
                else
                    sb.Append(c);
            }
            return sb.ToString();
        }

你说“后发”你得到了奇怪的字符。你的意思是服务器用这种方式解释字符吗？或者你的客户端，当你读取响应时，得到了奇怪的字符。你是否检查了

bytedata

数组以验证你发送的字节是ISO-8859-1？你说你收到的在我看来非常像UTF-8…妈ybe是另一个例子。我有如下字符串：█████████ & 我讨厌扩展ASCII…然后我使用HttpUtility.UrlEncode对文本进行编码。我得到这样的结果：%e2%96%88%e2%96%88%e2%88%e2%96%88%e2%96%88%e2%96%88%e2%96%88%e2%96%88+26+I+hate+extended+ASCII…这是错误的。应该是这样的（我用fiddler和google chrome阅读）：%26%239608%3B%26%239608%3B%26%239608%3B%26%239608%3B%26%239608%3B%26%239608%3B%26%239608%3B%26%239608%3B+%26+I+hate+extended+ASCII
