C# socket接收单片机数据问题

Question

单片机通过wifi将采集到传感器的数据传至上位机，单片机是每一秒发送一组数据，如“0xaa，0x55，‘采集到的数据1’，‘采集到的数据2’”
问：怎样才能接收数据并判断第一个是“0xaa“并且第二位是”0x55“时候将”采集到的数据1“和”采集到的数据2“拿出来并整合合，下一秒也是这样循环下去，我现在只能做到接收数据。
private byte[] m_receiveBuffer = new byte[1024];
sock.BeginReceive(m_receiveBuffer, 0, m_receiveBuffer.Length, 0, new AsyncCallback(ReceiveCallBack), null);
private void ReceiveCallBack(IAsyncResult ar)
{
try
{
int REnd = sock.EndReceive(ar);

                string strReceiveData = m_receiveBuffer[0].ToString("X2");
                this.HandleMessage(strReceiveData);
                sock.BeginReceive(m_receiveBuffer, 0, m_receiveBuffer.Length, 0, new AsyncCallback(ReceiveCallBack), null);

        }
        catch (Exception ex)
        {
            throw new Exception(ex.Message);
        }
            }       

private void HandleMessage(string message)
{
message = message.Replace("\0", "");
if (!string.IsNullOrEmpty(message))
{
label6.Text = message;
}

    }

已解决，不过还需要优化，比如延时问题
