Question

我在C＃中使用HttpRequest进行网站互动我可以阅读页面内容但是当我尝试将一些信息发回服务器时，一切正常但不是页面中TextArea s的价值...
我试图为其设置的文字是波斯语（波斯语），我接收的页面设置为 Windows-1256 编码。。

问题是textarea的内容没有像我在波斯语中所期望的那样显示！

更新：以下是我用来发送请求的代码：

public static string PostMultipart(string URL, List<RequestParameterInfo> parameters, List<string> cookies, string referer, string acceptLanguage, string acceptCharset, object KeepAliveValue)
{
   HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(URL));
   var boundary = "---------------------------7dc283270344";
   var messageBytes = Encoding.UTF8.GetBytes("--" + boundary);

   foreach (var item in parameters)
   {
      var prefixBytes = Encoding.UTF8.GetBytes("\n");
      var itemBytes = item.ToBytes();
      var postfixBytes = Encoding.UTF8.GetBytes("\n--" + boundary);

      var startIndex = messageBytes.Length;
      Array.Resize<byte>(ref messageBytes, messageBytes.Length + itemBytes.Length + prefixBytes.Length + postfixBytes.Length);

      prefixBytes.CopyTo(messageBytes, startIndex);
      itemBytes.CopyTo(messageBytes, startIndex + prefixBytes.Length);
      postfixBytes.CopyTo(messageBytes, startIndex + prefixBytes.Length + itemBytes.Length);
     }

     var lastPostfixBytes = Encoding.UTF8.GetBytes("--");
     var startIndex2 = messageBytes.Length;
     Array.Resize<byte>(ref messageBytes, messageBytes.Length + lastPostfixBytes.Length);
     lastPostfixBytes.CopyTo(messageBytes, startIndex2);




     request.Headers.Clear();
     request.Accept = "application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, */*";
     request.Headers.Add(HttpRequestHeader.Pragma, "no-cache");
     request.ContentLength = messageBytes.Length;

     request.Referer = referer;
     request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3)";
     request.ContentType = "multipart/form-data; boundary=" + boundary;
     request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip, deflate");
     request.Headers.Add(HttpRequestHeader.AcceptLanguage, acceptLanguage);

     if (!string.IsNullOrWhiteSpace(acceptCharset))
         request.Headers.Add(HttpRequestHeader.AcceptCharset, acceptCharset);

     if (KeepAliveValue is Boolean)
         request.KeepAlive = (bool)KeepAliveValue;
     else
         request.Headers.Add(HttpRequestHeader.KeepAlive, (string)KeepAliveValue);

     request.Expect = null;

     request.CookieContainer = new CookieContainer();
     foreach (var item in cookies)
         request.CookieContainer.SetCookies(new Uri(URL), item);

     request.AllowWriteStreamBuffering = true;
     request.Method = "POST";

     using (var strm = request.GetRequestStream())
     {
         strm.Write(messageBytes, 0, messageBytes.Length);
     }

     string resPage = "";
     using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
     {
         using (StreamReader srResponse = new StreamReader(response.GetResponseStream()))
         {
             resPage = srResponse.ReadToEnd();
         }
     }

     return resPage;
 }

更改您的Form元素以使用正确的编码：

<form method="post" accept-charset="Windows-1256" />

或<form accept-charset="utf-8" />

<强>更新

request.ContentType = "multipart/form-data; charset: utf-8; boundary=" + boundary;

UTF-8不适用于TextArea内容
