如何将一串string类型的16进制字符串转成byte[]数组？

[boyyao]

比如如下一串字符串
080003005844967d
要转成
byte[] b = {0x08,0x00,0x03,0x00.......0x7d}

[threenewbee]

string s = "080003005844967d";
byte[] b = new byte[s.Length / 2]
for (int i = 0; i < s.Length; i += 2)
b[i / 2] = Convert.ToByte("0x" + s.SubString(i, 2));

用这个
Convert.ToByte

        static void Main(string[] args)
        {
            string str = @"080003005844967d";
            List<byte> bytes = new List<byte>();
            for (int i = 0; i < str.Length; i += 2) {
                string strTemp = str.Substring(i, 2);
                byte b = Convert.ToByte(strTemp, 16);
                bytes.Add(b);
            }
            byte[] result = bytes.ToArray();
            foreach (byte b in result) {
                Console.WriteLine("0x"+string.Format("{0:X}", b).PadLeft(2, '0'));
            }
        }

string a="fdsfgfsdfsdfsd442342";
char[] b=convert.tochararray(a);
byte[] c=Encoding.Default.GetBytes(b);
