Question

字符串string s="0xaa 0x01 0x23 0xff"分割字符串后，如何存储到字节数据中？

我只得得出字符串数据，分别存储string[] result={"0xaa ","0x01 ","0x23 ","0xff"}，转化存储到byte[]bb时有问题

Answer 1

string s = "0xaa 0x01 0x23 0xff";
string[] strArray = s.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
byte[] binArray = new byte[strArray.Length];
for (int i = 0; i < binArray.Length; i++)
{
binArray[i] = byte.Parse(strArray[i].Substring(2), System.Globalization.NumberStyles.HexNumber);
}

Answer 2

string[] s = new string[] { "0xaa ", "0x01 ", "0x23 ", "0xff" };

int len = s.Length;

byte[] b = new byte[len];

b.CopyTo(s, 0);
