byte类型是分不清0和00的。所以这个需求不成立

nt main(void) 4{ 5 unsigned char array[4] = {"0x0","0x0","0x02","0xe7"}; 6 unsigned long num; 7 num = 0; 8 for(int i=0;...

利用System.Convert.ToByte方法可以将 0x开始的十六进制格式字符串转换成byte类型值。例如 string s = "0x55";byte b = System.Convert.ToByte(s, 16);Console.WriteLine(b); //输出85s = "0xff";b = System.Convert.ToByte(s, 16);Console.Writ...
