Tcp粘包处理+无脑处理

　　大家都知道tcp会粘包的，比如你用1m去接收，它正常的单条数据是220，那么就会产生 5 到 6 个粘包体，我们只能打标识，用结束字符去分割处理。我写的一个类，仅供大家参考。

public void Split(byte[] receiveData){
//整体的标识
            List<int> end_index = new List<int>();
            ///循环该粘包总体数据
            for (int i = 0; i < receiveData.Length; i++)
            {
                //最后4位直接检索
                if (i + 3 == receiveData.Length)
                    break;
                //先找到粘包的结束标识
                if (receiveData[i] == 0xaa && receiveData[i+1] 
                    == 0xaa && receiveData[i+2] == 0xaa && receiveData[i+3] == 0xaa)
                {
                    end_index.Add(i + 3);//结束的标识
                }
            }
            for (int i = 0; i < end_index.Count; i++)
            {
                //判断是否有未结束的数据
                if (redis_buffer_byte.Length != 0)
                {
                    // 未结束的 + 第一个结束标识
                    byte[] RealData = new byte[end_index[i] + redis_buffer_byte.Length];
                    redis_buffer_byte.CopyTo(RealData, 0);
                    receiveData.Skip(end_index[i])
                                     .Take(end_index[i]+i).ToArray()
                                        .CopyTo(RealData, redis_buffer_byte.Length);
                    //清空剩余byte
                    redis_buffer_byte = new byte[] { };
                    if (RealData.Length == 108 || RealData.Length == receiveData.Length)
                        return;
                    TCP_AddWireless(RealData);
                }
                else
                {
                    //不证明是最后一个
                    if (i != end_index.Count -1)
                    {
                        // 前一个标识 + 后一个标拾
                        byte[] RealData = new byte[end_index[i+1] - end_index[i]];
                        //receiveData.CopyTo(RealData,end_index[i]);
                        Array.Copy(receiveData,end_index[i],RealData,0, RealData.Length);
                        if (RealData.Length == 108)
                            return;
                        TCP_AddWireless(RealData);
                    }
                    else
                    {
                        //添加到剩余粘包队列中
                        byte[] RealData = new byte[receiveData.Length - end_index[i]];
                        redis_buffer_byte = RealData;
                    }
                }
            }
}

　　这样调试起来还是很费劲的，如果是无脑的话哈哈哈，你用这个吧。

public void Split_TcpData(byte[] receiveData)
      {
          for (int i = 0; i < receiveData.Length; i++)
          {
              if (i + 3 == receiveData.Length)
                  break;
              if (receiveData[i] == 0xee && receiveData[i + 1]
                  == 0xee && receiveData[i + 2] == 0xee && receiveData[i + 3] == 0xee)
              {
                  for (int y = i; y < receiveData.Length; y++)
                  {
                      if (y + 3 == receiveData.Length)
                          break;
                      if (receiveData[y] == 0xaa && receiveData[y + 1]
                          == 0xaa && receiveData[y + 2] == 0xaa && receiveData[y+ 3] == 0xaa)
                      {
                          byte[] RealData = new byte[y - i + 4 ];
                          Array.Copy(receiveData, i, RealData, 0,RealData.Length);
                          if (RealData.Length > 146  &&  RealData.Length < 184)
                          {
                              TCP_AddWireless(RealData);
                          }
                      }
                  }
              }
          }
      }
