问题描述
我正在尝试将此字符串数组转换为字节数组.
I'm trying to convert this string array to byte array.
string[] _str= { "01", "02", "03", "FF"};
to byte[] _Byte = { 0x1, 0x2, 0x3, 0xFF};
我尝试了以下代码,但它不起作用._Byte = Array.ConvertAll(_str, Byte.Parse);
I have tried the following code, but it does not work. _Byte = Array.ConvertAll(_str, Byte.Parse);
而且,如果我可以将以下代码直接转换为字节数组,那就更好了:string s = "00 02 03 FF"
to byte[] _Byte = { 0x1, 0x2, 0x3, 0xFF};
And also, it would be much better if I could convert the following code directly to the byte array :string s = "00 02 03 FF"
to byte[] _Byte = { 0x1, 0x2, 0x3, 0xFF};
推荐答案
这应该有效:
byte[] bytes = _str.Select(s => Convert.ToByte(s, 16)).ToArray();
使用Convert.ToByte
,您可以指定基数从中转换,在你的情况下,是 16.
using Convert.ToByte
, you can specify the base from which to convert, which, in your case, is 16.
如果你有一个用空格分隔值的字符串,你可以使用 String.Split
将其拆分:
If you have a string separating the values with spaces, you can use String.Split
to split it:
string str = "00 02 03 FF";
byte[] bytes = str.Split(' ').Select(s => Convert.ToByte(s, 16)).ToArray();
