c＃Tcp客戶端傳輸文件與sslStream

我嘗試發送帶有TCP客戶端的sslStream的文件。文件大約是250kb。當我不寫dataLength流，服務器關閉連接我的事情，因爲最大接收緩衝區大小。當我寫入流的dataLength，我沒有例外，但服務器有一個類型的錯誤（連接優雅地關閉）。一個原因是，由於Tcp客戶端關閉事件，服務器無法接收我發送的數據;這是我的代碼。服務器代碼丟失，我知道，它已經在德爾福與印插座庫writen 這裏是我的代碼c＃Tcp客戶端傳輸文件與sslStream

TcpClient sendClient = new TcpClient(serverName, port); 
     LingerOption lingerOption = new LingerOption(true, 20); 
     sendClient.LingerState = lingerOption; 
     using (SslStream sendStream = new SslStream(sendClient.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null)) 
     { 

      try 
      { 

       sendStream.AuthenticateAsClient(serverName, null, SslProtocols.Ssl2, true); 


       sendStream.Write(Encoding.UTF8.GetBytes("Login\r\n" + username + "\r\n" + password + "\r\n")); 
       sendStream.Flush(); 
       int bytesResp = -1; 
       byte[] buffer = new byte[1024]; 

       bytesResp = sendStream.Read(buffer, 0, buffer.Length); 

       string response = Encoding.UTF8.GetString(buffer, 0, bytesResp); 

       if (response.Trim() == "OK") 
       {

          Array.Clear(data, 0, data.Length);

我不知道它是否會有所幫助，但我也有類似的問題，使用（）{}由於某種原因，它關閉了sslstream。所以去除可能

using (SslStream sendStream = new SslStream(sendClient.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null)){}

到

SslStream sendStream = new SslStream(sendClient.GetStream(), false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null);
