识别套接字消息（扩展名）在十进制和十六进制之间切换

Question

这是another question.

扩展中的问题

我想知道：

1. 如果代码显示为workSocket.dataBuffer[3]，则它等于workSocket.dataBuffer[0x33]，对吗？但是从enter link description here，33转换为51，因此workSocket.dataBuffer[0x33]对应workSocket.dataBuffer[51]？

2. 下面的代码执行了很多| =比较和移位字节＆lt;＆lt ;.这些比较的用途是什么？

3. 如果我想将workSocket.m_Ch1设为40，将workSocket.m_Ch2设为40，那么输入workSocket.dataBuffer应该是什么？

代码如下：

workSocket.UniqueNum = (uint) (((workSocket.dataBuffer[0xb9] << 8) | workSocket.dataBuffer[0xb8]) | -2147483648);
workSocket.Information = 0;
workSocket.Information |= (uint) ((workSocket.dataBuffer[0x1b] & 12) << 8);
workSocket.Information |= (uint) ((workSocket.dataBuffer[40] & 12) << 6);
workSocket.Information |= (uint) ((workSocket.dataBuffer[0x76] & 12) << 4);
workSocket.Information |= (uint) ((workSocket.dataBuffer[0x1b] & 3) << 4);
workSocket.Information |= (uint) ((workSocket.dataBuffer[40] & 3) << 2);
workSocket.Information |= (uint) (workSocket.dataBuffer[0x76] & 3);
workSocket.Information |= 0xc0000000;

num2 = (workSocket.dataBuffer[0x10] << 8) + workSocket.dataBuffer[15];
if (num2 > 10)
      {
       workSocket.m_Ch1 = ((float) (num2 + 190)) / 228f;
      }
else
      {
       workSocket.m_Ch1 = 0f;
      }
num2 = (workSocket.dataBuffer[0x1f] << 8) + workSocket.dataBuffer[30];
if (num2 > 10)
      {
      workSocket.m_Ch2 = ((float) (num2 + 0x99)) / 236f;
      }
else
      {
      workSocket.m_Ch2 = 0f;
      }
