求高手给我解释一下这几个方法是什么意思
index是个全局变量，初始值为0

public  short readShort(byte[] dis)
        {
            int firstByte = dis[index++];
            int secondByte = dis[index++];
            return (short)(firstByte & 0xff | secondByte << 8);
        }

        public  byte readByte(byte[] dis)
        {
            return (byte)(dis[index++] & 0xff);
        }

        public  int readInt(BinaryReader dis)
        {
            
            int a = dis.Read();
            int b = dis.Read();
            int c = dis.Read();
            int d = dis.Read();
            if ((a | b | c | d) < 0)
                throw new Exception();
            else
                return (d << 24) + (c << 16) + (b << 8) + (a << 0);
        }

        public  char readChar(BinaryReader dis)
        {
            int a = dis.Read();
            int b = dis.Read();
            if ((a | b) < 0)
                throw new Exception();
            else
                return (char)((b << 8) + (a << 0));
        }

对位运算符不了解 。学习

[24K純帥]

介个都是用二进制读取int,short,char

[yinsuxia]

顶起来，难道没人能给解释解释？？

[昵称很不好取]

把存放在byte数组中的字节序列，转换为小端模式的数值
