例如： int bytesRead = 0; int bytesToRead = 1024; byte[] input = new byte[bytesToRead]; while (bytesRead...<bytesToRead){ bytesRead += in.read(input,bytesRead,bytesToRead - bytesRead); } 上面这段代码就是没有考虑到有可能流会中断导致读取的数据永远读不出来...，所以要防止这种事情出现需要先测试read()的返回值，然后再增加到byteRead中 如下所示： int bytesRead = 0; int bytesToRead = 1024; byte[] input...= new byte[bytesToRead]; while (bytesRead<bytesToRead){ int result = in.read(input,bytesRead,bytesToRead
blockSize]; int bytesRead; int downloadedBytes = 0; while (downloadedBytes < totalFileSize) { int bytesToRead...); connection.setRequestProperty("Range", "bytes=" + downloadedBytes + "-" + (downloadedBytes + bytesToRead...InputStream inputStream = connection.getInputStream(); bytesRead = inputStream.read(buffer, 0, bytesToRead
System.Threading.Thread.Sleep(20); byte[] _data = new byte[_serialPort.BytesToRead...while (num++ < Overtime) { if (_serialPort.BytesToRead...System.Threading.Thread.Sleep(10); } if (_serialPort.BytesToRead...{ ret = _serialPort.Read(ReceiveData, 0, _serialPort.BytesToRead
bytSend.Length); Thread.Sleep(100);//确保数据发送及解析时间 int n = SPort.BytesToRead...CRC去 SPort.Write(bytSend, 0, bytSend.Length); Thread.Sleep(100); int n = SPort.BytesToRead
byte[] buffer = new byte[blockSize]; int bytesRead; while (downloadedBytes < totalFileSize) { int bytesToRead...); connection.setRequestProperty("Range", "bytes=" + downloadedBytes + "-" + (downloadedBytes + bytesToRead...InputStream inputStream = connection.getInputStream(); bytesRead = inputStream.read(buffer, 0, bytesToRead
