将 String[] 转换为 byte[] 数组 [英] Convert String[] to byte[] array

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();
