Webclient UploadValues 编码

Question

我在 URL 中创建了一个 POST 并得到了这样的字符串形式的响应：

var responseBytes = client.UploadValues("www.example.com", requestData.Body);
var html = Encoding.UTF8.GetString(responseBytes, 0, responseBytes.Length);
html = HttpUtility.HtmlDecode(html);

我创建了一个 WebClient 子节点来接受 cookie，所以我做了一个 class:

 public class CookieWebClient : WebClient
{
    public CookieContainer CookieContainer { get; }

    public CookieWebClient()
    {
        CookieContainer = new CookieContainer();
        Encoding = Encoding.UTF8;
    }

    public CookieWebClient(CookieContainer cookieContainer)
    {
        CookieContainer = cookieContainer;
    }

    protected override WebRequest GetWebRequest(Uri address)
    {
        var request = base.GetWebRequest(address) as HttpWebRequest;
        if (request == null) return base.GetWebRequest(address);
        request.CookieContainer = CookieContainer;
        return request;
    }
}

如您所见，我在构造函数中设置了编码。但是当我得到 html 属性时，一些字符会出现：� necess�rio，它应该是 É necessário。

有什么想法吗？

您正在使用 "Latin 1" 个字符（可能是葡萄牙语？），所以您应该使用：

var html = Encoding.GetEncoding("ISO-8859-1")
                   .GetString  (responseBytes, 0, responseBytes.Length);
