Webclient UploadValues编码

Question

我在URL中创建POST并将响应作为字符串获取，如下所示：

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子项来接受cookie，所以我创建了这个类：

 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，当我获得html属性时，某些字符会变为：� necess�rio，它应该是É necessário。

任何想法都错了吗？

你正在使用“拉丁语1”字符（葡萄牙语，也许？），所以你应该选择：

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