[C#]解决读写包含汉字的txt文件时乱码的问题 (4)                 byte byte4 = 0;

                int nByte = stream.ReadByte();

                byte1 = Convert.ToByte(nByte);

                byte2 = Convert.ToByte(stream.ReadByte());

                if(stream.Length >= 3)

                {

                    byte3 = Convert.ToByte(stream.ReadByte());

                }

                if(stream.Length >= 4)

                {

                    byte4 = Convert.ToByte(stream.ReadByte());

                }

                //根据文件流的前4个字节判断Encoding

                //Unicode {0xFF, 0xFE};
