HTTP後切斷字符串

Question

我正在使用以下代碼來執行HTTP Post。這在大多數情況下工作正常，但切斷我的字符串在一定的長度約4300字符串字符。我怎樣才能解決這個問題？我有一種預感，認爲這與所有未發佈的數據相關，並且在發佈期間中斷。我怎樣才能解決這個問題？

ASCIIEncoding encoding = new ASCIIEncoding(); 
       // Create a request using a URL that can receive a post. 
       WebRequest request = WebRequest.Create("<URL>"); 
       // Set the Method property of the request to POST. 
       request.Method = "POST"; 
       // Create POST data and convert it to a byte array. 
       string postData = "json=" + json; 
       //string postData = "json=blah"; 
       byte[] byteArray = Encoding.UTF8.GetBytes(postData); 
       // Set the ContentType property of the WebRequest. 
       request.ContentType = "application/x-www-form-urlencoded"; 
       // Set the ContentLength property of the WebRequest. 
       request.ContentLength = byteArray.Length; 
       // Get the request stream. 
       Stream dataStream = request.GetRequestStream(); 
       // Write the data to the request stream. 
       dataStream.Write(byteArray, 0, byteArray.Length); 
       // Close the Stream object. 
       dataStream.Close(); 
       // Get the response. 
       WebResponse response = request.GetResponse(); 
       // Display the status. 
       //Console.WriteLine(((HttpWebResponse)response).StatusDescription); 
       // Get the stream containing content returned by the server. 
       dataStream = response.GetResponseStream(); 
       // Open the stream using a StreamReader for easy access. 
       StreamReader reader = new StreamReader(dataStream); 
       // Read the content. 
       retVal = reader.ReadToEnd(); 

       // Clean up the streams. 
       reader.Close(); 
       dataStream.Close(); 
       response.Close();

那個Uri.EscapeDataString（json）做了詭計。
