问题描述
我需要一个数组,数组中的每个项目就是这样一个字节数组,但我不知道该怎么办了:
暗淡作为XX数组XX(0)*为字节* = {&放大器; H12,和放大器; HFF}XX(1)*为字节* = {&放大器; H45,和放大器; HFE}
您可以嵌套或锯齿状的字节数组是这样的:
暗淡myBytes(6)()为字节
这将创建6字节数组空数组。外阵列中的每个元素将是没有
,直到你将数组分配给它,就像这样:
myBytes(0)=新的字节(){&安培; H12,和放大器; HFF}
但是,它很可能是一个更好的主意,使列表
字节数组的,像这样的:
昏暗myBytes作为新的列表(字节())
,直到你把一些字节数组到它这将创建一个字节数组的一个空列表,这会留下空的,像这样的:
myBytes.Add(新的字节(){&安培; H12,和放大器; HFF})
与嵌套阵列,列表(字节())
将自动扩展为你把它保存尽可能多的字节数组。
有关更具体的建议,请告诉我们你想要做的事。
I need an array and each item in the array is an array of bytes like this, but I'm not sure how to do the:
Dim xx as array
xx(0) *as byte* = {&H12, &HFF}
xx(1) *as byte* = {&H45, &HFE}
You can make a nested or "jagged" byte array like this:
Dim myBytes(6)() As Byte
This will create an empty array of 6 byte arrays. Each element in the outer array will be Nothing
until you assign an array to it, like this:
myBytes(0) = New Byte() { &H12, &Hff }
However, it would probably be a better idea to make a List
of byte arrays, like this:
Dim myBytes As New List(Of Byte())
This will create an empty list of byte array, which will stay empty until you put some byte arrays into it, like this:
myBytes.Add(New Byte() { &H12, &Hff })
Unlike the nested array, a List(Of Byte())
will automatically expand to hold as many byte arrays as you put into it.
For more specific advice, please tell us what you're trying to do.
