答案 0 :(得分：1)
问题是您在发送回服务器时没有对POST数据进行编码。您可以使用WebUtility.UrlEncode对其进行封尾。
以下是对您的代码的修改：
注意：在using中包装第二个请求函数，就像我为您做的第一个请求一样：

using (var s = hr.GetResponseStream())

using (var r = new StreamReader(s, Encoding.UTF8))
{

//Console.WriteLine(html);
Match mVS = Regex.Match(html, "id=\"__VIEWSTATE\" value=\"(.*?)\"", RegexOptions.Singleline);
