流量高位数据转换，谁做过，请指导下

以下是低位的数据转换过程，大家看看高位怎么转换啊
If index = 1 Then '流量累积值低位数据转换
  A(0) = "&H" + CStr(Hex(recive(3)))
  A(1) = "&H" + CStr(Hex(recive(4)))
  A(2) = "&H" + CStr(Hex(recive(5)))
  A(3) = "&H" + CStr(Hex(recive(6)))
   
  '先用一个临时数组倒序数组A
  Dim B(3) As Byte
  Dim p As Integer
  For p = 0 To 3
  B(p) = A(3 - p)
  Next p
  CopyMemory Resultl, B(0), 4
  dd = Resultl
  Text1.Text = CStr(recdata) '显示返回命令
  End If

A(0) = "&H" + CStr(Hex(recive(3)))
  A(1) = "&H" + CStr(Hex(recive(4)))
  A(2) = "&H" + CStr(Hex(recive(5)))
  A(3) = "&H" + CStr(Hex(recive(6)))
-----------------------------------------
这一段代码写的很无语
直接A(0) = recive(3)不就行了吗？
最多写成A(0) = cByte(recive(3))
这一通类型转换真够累人的
