[转]C#写封包挂需要用到的一些函数

主要是在处理参数时需要格式化成Hex格式，我自己写了2个函数

    private Byte[] GetBytes(Int32 length, params Int32[] args)
        {
            Byte[] data = new Byte[args.Length * length];
            String str = String.Empty;

            for (int i = 0; i < args.Length; i++)
            {
                Byte[] tempData = BitConverter.GetBytes(args);
                for (int j = 0; j < length; j++)
                {
                    data[i * length + j] = tempData[j];
                }
            }

            return data;
        }

        private Byte[] MergeBytes(params Byte[][] args)
        {
            Int32 length = 0;
            for (int i = 0; i < args.Length; i++)
            {
                Byte[] tempByte = args;
                length += tempByte.Length;
            }

            Byte[] bytes = new Byte[length];

            Int32 tempLength = 0;
            for (int i = 0; i < args.Length; i++)
            {
                Byte[] tempByte = args;
                tempByte.CopyTo(bytes, tempLength);
                tempLength += tempByte.Length;
            }

            return bytes;

        }


使用方式：

        public void SkillAttack(Int32 skillID, Int32 monsterID)
        {
            Byte[] headBytes = new Byte[] { 0x29, 0x00};
            Byte[] skillIDBytes = GetBytes(2, skillID);
            Byte[] fixBytes = new Byte[] { 0x00, 0x00, 0x00, 0x01 };
            Byte[] monsterIDBytes = GetBytes(4, monsterID);

            Byte[] data = MergeBytes(headBytes, skillIDBytes,fixBytes, monsterIDBytes);

            SendPackage(data);
        }
