UTF8 编码 C# Webrequest

Question

我正在尝试发出一个网络请求并用希伯来语发送一个帖子数据，但服务器端得到它像“?????” 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，服务器将发布数据作为“???? ???-????????? ????” 但我应该对“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);
