c＃SslStream.EndRead返回零字節

Question

我的服務器程序，部署在很多產品環境上運行良好，在我們所期望的不運行的機器上購買。

在這個機器上，當我們調用SslStream.BeginRead，那麼當SslStream.EndRead調用0的回報，如果我們不關閉流，並再次調用SslStream，有扔一個例外。

private void Read() 
    { 
     try 
     { 
      if (this._IsClosed) 
      { 
       return; 
      } 
      this._Stream.BeginRead(this._Buffer, 0,  BufferManager.Default.OutterReadBufferSize, this.EndRead, null); 
     } 
     catch (Exception ex) 
     { 
      _Logger.WarnFormat("Begin Read, session:{0}, {1}", this._Id, ex); 
      this.Close(); 
     } 
    } 





private void EndReadTaskAction(object ar) 
    { 
     try 
     { 
      int len = this._Stream.EndRead((IAsyncResult)ar); 
      int used = 0; 
      if (len <= 0) 
      { 
       _Logger.WarnFormat("EndReadTaskAction len less or equal zero, len={0}, session={1}", len, _Id); 
       this.Close(); 
       return; 
      } 

      if (this._HasPartialPacket) 
      { 
       if (this._PartialReadedLenth < PacketConstants.HeadLength) 
       { 
        int needToRead = PacketConstants.HeadLength - this._PartialReadedLenth; 
        if (needToRead > len) 
        { 
         Buffer.BlockCopy(this._Buffer, used, this._Buffer, GetCurrentPartialReadIndex(), len); 
         this._PartialReadedLenth += len; 
         Read(); 
         return; 
        } 
        Buffer.BlockCopy(this._Buffer, used, this._Buffer, GetCurrentPartialReadIndex(), needToRead); 
        len -= needToRead; 
        used += needToRead; 
        this._PartialReadedLenth += needToRead; 
       } 
       int packetLength = PacketHelper.GetPacketLength(this._Buffer, this._PartialReadIndex); 
       int howMuchNeedToRead = packetLength - this._PartialReadedLenth;

       { 
        Buffer.BlockCopy(this._Buffer, used, this._Buffer, GetCurrentPartialReadIndex(), len); 
        this._PartialReadedLenth += len; 
        Read(); 
        return; 
       } 
       Buffer.BlockCopy(this._Buffer, used, this._Buffer, GetCurrentPartialReadIndex(), howMuchNeedToRead); 
       ProcessPackage(this._Buffer, this._PartialReadIndex, packetLength); 
       len -= howMuchNeedToRead; 
       used += howMuchNeedToRead; 
      } 
      this._HasPartialPacket = false; 
      this._PartialReadedLenth = 0; 
      while (true) 
      { 
       if (len <= 0) 
       { 
        break; 
       } 

       if (len < PacketConstants.HeadLength) 
       { 
        Buffer.BlockCopy(this._Buffer, used, this._Buffer, this._PartialReadIndex, len); 
        this._PartialReadedLenth = len; 
        this._HasPartialPacket = true; 
        break; 
       } 
       int packetLength = PacketHelper.GetPacketLength(this._Buffer, used); 
       if (len < packetLength) 
       { 
        Buffer.BlockCopy(this._Buffer, used, this._Buffer, this._PartialReadIndex, len); 
        this._PartialReadedLenth = len;

       } 
       ProcessPackage(this._Buffer, used, packetLength); 
       used += packetLength; 
       len -= packetLength; 
      } 
      if (_isBeginRead) 
      { 
       Read(); 
      } 
     } 
     catch (Exception ex)

您在部署的服務器上表示您沒有任何問題，並且在新計算機中出現問題，請檢查所有dll的include和它的依賴關係，.net框架運行時。

希望它可以幫助..
