c# - UTF8 编码 C# Webrequest

Question

我正在尝试发出网络请求并发送希伯来语的帖子数据但服务器端得到它就像“??????”而不是希伯来语。

    WebRequest request = WebRequest.Create(MyserverClient.Url + Constants.TaskUpdatePropertyURL);
((HttpWebRequest)request).AllowAutoRedirect = false;
((HttpWebRequest)request).KeepAlive = true;

request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded;";
request.Headers.Add("Pragma: no-cache");
request.Headers.Add(string.Format("Cookie: {0}", Client.phpId));
    request.Headers.Add(string.Format("requesttoken: {0}", requestToken));

    string postData = "Some Non-english text";      
    using (Stream dataStream = request.GetRequestStream())
{
    byte[] byteArray = Encoding.UTF8.GetBytes(postData);                
    dataStream.Write(byteArray, 0, byteArray.Length);               
    dataStream.Close();
}

    try{
     HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                // Get the stream containing content returned by the server.
         Stream dataStream2 = response.GetResponseStream ();
                // Open the stream using a StreamReader for easy access.
        StreamReader reader = new StreamReader (dataStream2);
                // Read the content. 
        responseFromServer = reader.ReadToEnd ();
    }
 return responseFromServer;

        } 

正如我所说，对于非英语服务器，服务器获取的帖子数据为“???? -??????????????”但我应该是“一些非英文文本”有什么建议吗？？

尝试这样的事情:

StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8);
